Title: Our First Build - Billings Banckert 516
Post by: Phil22 on June 11, 2019, 10:35:16 AM
Hi Everyone,

Great to now be active on the MBM Forum. Looking around at the wealth of shared experience is an inspiration. My GF and I hope to make our own contributions as we embark on our first build, a Billings Banckert 516.

Growing up by the sea, river tugs have always caught my eye the most. For me their shape is perfect, having a definite timeless quality.

This project is something we are working on together; I've some carpentry skills and can make tea, my better half is good with science and is not easily frustrated (this will come in handy as the build plans are let's say 'challenging'). Neither of us has any experience with electronics, this is something we'd like to learn more about to get running lights on board.

Hmmm...

There seems to be something amiss with the link to your pictures.  If you want them to appear in your post, do this (I assume you have uploaded your pics to the MBM image site)  -

Select the image you want to post, then click on Embed Codes under the picture.  In the Full Image section, put your cursor over the BBCode line and a small box saying Copy should appear.  Click on this, then go to your message and paste that where you want the picture to appear.  I did all that and...

Good luck with the build.  Keep asking questions, there will always be answers and the rest of us will learn something as well.

Title: Help to bond ABS to Plywood - Billings Banckert 516
Post by: Phil22 on June 14, 2019, 03:35:28 PM
Hi All,


Does anyone have a recommended way of bonding ABS to plywood? A number of threads mention epoxy and yellow glue for example. We are currently living in Japan and having tested 6 types of both flexible and stiff drying Japanese glues, so far nothing has stuck. The ABS has been roughed up but the bonds have simply peeled off even after 48 hours of drying. Any brand names would be appreciated that we could order online.


Thanks,
Phil

Stabilit express (stability express more commonly marketed as). Don't know if you can get it in shops in far east. I had to order from Germany via eBay.

Hey Rich, thank you so much for the reply.
We've done some initial searches here but would probably have to order from Germany too it looks like.
Appreciate your help  :-))

No worries. Always fancied a banckert, but the wood puts me off these days, and they're getting expensive here when I see them. Do you know tamiya make a liquid solvent for abs to abs, you'll get that easy peasy.

Thanks again Rich, will look out for that here (Tokyo). I was really surprised as so far I've not found any model shops which carry boats and parts. There are plenty of car, planes, helis and drones to be found. Wonder if there are any other Mayhemers here. We ordered the Banckert from a stockist a fair way from the capital (too far to visit).


Today was the first day working with the laser cut wood in the kit. Although it starts off pretty scorched on the underside, with a bit of light sanding it comes up nice. We've already decided that the plans are merely a loose guide. With a square and some creative license. pleasing results can be had. Here are some more pics of today's efforts.


(https://www.modelboatmayhemimages.co.uk/images/2019/06/15/8.jpg)
Heated a spike on the stove and made a pilot hole before using a 2mm bit and finishing the rest by hand.

Post by: Ralph on June 15, 2019, 08:24:08 PM
Built a Banckert years ago. It's a nice wee kit. I added a bow trusted to mine cos I'd never tried one before but it handled well without using the thruster. I think I replaced some of the plywood with styrene sheet to get a better finish without all the filling and sanding.


I'd be surprised if a 2 part epoxy doesn't bond ply to roughened ABS but acrylic glues stick just about anything to anything else - Stabilit Express as has been suggested or the one I use at the moment is called Super Crylic.


Good luck with your build.  Ralph
Title: Re: Our First Build - Billings Banckert 516
Post by: Phil22 on June 16, 2019, 12:57:53 PM
Thanks Ralph for the reply and info about Super Crylic. In your experience, how is it to sand and shape post curing?

Today we removed a little more out of the deck and sured up the frame that sits below with corner pieces and a cross-brace. This part of the deck has around a 2mm curve front to aft so it might be a bit of challenge to get the balsa insert to bend that much. We'll see.

Wow Billings Banckert with the ABS hull was my first modelboat way back in time and before laser cuts. Still have it but it needs some TLC.
If you are on FB try to look up Mr Nobuhisa Watanabe he is located in Tokyo and do "play" with modelboats he may be able to point you in the right direction for modelboat parts in Tokyo.

Post by: Ralph on June 16, 2019, 08:14:54 PM
Acrylic glues set very hard so they take a bit of work to sand smooth.  Riffler files are good to take off the worst in awkward places then finish off with wet & dry.

Hey Pat, yes I have the 511 fittings kit (I believe it is all the brass fittings and lifebelts etc.) Some very nice detailed bits included. Looking forward to adding those on.
Title: Re: Our First Build - Billings Banckert 516
Post by: Phil22 on June 22, 2019, 09:02:33 AM
We had a little time today to work on the Banckert. Having received some kind advice from a local builder "Sugi-san" in Japan, we are now in the process of getting our hands on some epoxy. The Japanese name for it is: セメダイン ハイスーパー30 (Cemedine High Super 30).

Reading up on the build, I'd noted people mentioning that the wood isn't square in the kit. So far we've found it to be fine although offering it to the curved hull becomes the brain teezer. Test fitting part of the forward structure showed that the starboard side gets pushed out of square at the front by the desk's molding. The side will go back to square but we saw the whole piece edge away (about 4mm) from the intended position. We've put a 2mm bead under the wheelhouse floor to make sure we retain square during assembly. The deck may need a bit of light persuasion.

Some light sanding to remove the mild laser burn

Title: Recommended Gear - Billings Banckert 516
Post by: Phil22 on June 24, 2019, 12:23:06 PM
Hi All,

For our Banckert project we'd like to ask for recommendations regarding running gear.
We haven't any experience to go off (yet), and so would ask what fellow MBMayhemers feel would be a solid basic setup (easily maintained). 

We have a few things in our minds at this point:

1. to achieve a scale-like speed (nothing overly fast for a tug)
2. a simple motor without gearing (very interested in brushless)
3. a brass prop
4. not planning to tow anything (we know "but it's a tug!")
25. way on down the line (ability allowing) we may 'attempt' adding in a self-contained bilge pump

So far we have the stuffing tube which came with the kit and that is all. So we really are starting from the beginning.
We appreciate that a 'solid basic setup' will mean different things to different people, we hope to get a better idea based on wisdom of this brilliant forum.

Cheers!

I believe that Billings kits come with fittings these days and not as separate purchases
This kit from CMB is a bargain at £180

Post by: Subculture on June 26, 2019, 11:13:42 AM
A good epoxy or modified acrylic glue will work fine for wood to ABS. Modified acrylics come under many brand names, and consistencies, Stabilit express is one, as is Deluxe materials Super Crylic, Devcon Plastic Welder I and II, Uhu Plus Acrylit, Loctite do a range, as do Starloc adhesives (very competitive prices).

For epoxy my favourite is JB weld marine, as it sands well, and being pigmented is easy to see where you have any where you don't want it.

Most of the glues will sand back, although some epoxies and modified acrylics can be a little chewy, the trick is to mask off areas you don't want overspill on, then apply the glue, that minimises any clean-up required.

Post by: Subculture on June 26, 2019, 11:22:51 AM
With regards to the motor, can you tell me the prop size? I'm guessing it'll be about 40-50mm for a tug that size and scale?
Title: Re: Our First Build - Billings Banckert 516
Post by: Phil22 on June 26, 2019, 02:04:27 PM
Thank you @Subculture for your information and advice. Very interested in the epoxy containing pigment. We were recommended this prop by a UK seller: Raboesch 40mm 3 Blade R/H C-Type.
The hull is 65cm long, 16cm wide (1:50)
Title: Re: Our First Build - Billings Banckert 516
Post by: Subculture on June 26, 2019, 04:56:13 PM
Raboesch tend to be roughly square props e.g. the pitch is roughly equal to the diameter. That tends to work very well with electric motors and is efficient. So I would aim for a shaft speed of between 4-5000rpm, which should give plenty of go, with a bit in reserve if needed.

A 28mm to 35mm brushless outrunner will run a prop that size direct drive all day long with no issues, depending on system voltage you'll want an outrunner that works at either (6v) 700kv or (12v) 350kv.

I'd go for a 6 volts system or 2s lipo/Life and a 700 kv motor e.g. https://hobbyking.com/en_us/turnigy-aerodrive-dst-700-brushless-outrunner-motor-700kv.html

Esc, something like this is a bit overkill, but not expensive and capable.

Post by: Subculture on June 26, 2019, 05:38:22 PM
Shouldn't experience any issues with those materials. You need to be careful with modified acrylic on some clear plastics like polycarbonate and PMMA as it can craze them. Epoxy is pretty much inert on anything, but the bond is completely mechanical, so the plastic surfaces need to be well keyed before bonding.
Title: Re: Our First Build - Billings Banckert 516
Post by: Martin [Admin] on June 26, 2019, 05:53:31 PM
 
Agreed but some ABS / 'hard plastic' single part glues have high solvent content and if used too liberally or the ABS is very thin..... !   {:-{
Title: Re: Our First Build - Billings Banckert 516
Post by: Subculture on June 26, 2019, 06:38:03 PM
All the glues I listed are twin component adhesives, Martin. You can't fuse wood to ABS, it has to be bonded.

@Subculture a million thanks for the information and ideas, this is perfect. With your explanation and links along with Andy and Martin's info we have a great base to do some spending (a-hem, I mean research)!! Yeah, will look into these products so we can try to understand them more and how they go together. We were really happy to receive the voltage information, this is something we were wondering about a lot.

Spent a few hours each evening this week continuing to work on the wooden bits. Also we got our hands on some Japanese epoxy for the ABS to plywood.

Used a square sanding block as a guide while coming along with the sides of this section. This was helpful in giving 3 points of contact while glueing

So far the laser-cut pieces have been great, only requiring some light sanding here and there. The rear deck was the first time something didn't quite go together flush. Rather than using some filler, we opted to cut, realign then slot in a fillet.

Title: Re: Our First Build - Billings Banckert 516
Post by: Phil22 on July 20, 2019, 03:09:38 AM

Began work on the rear deck railings (thanks to tips on the forum about working off a separate board). The stanchions in our case are not moveable post bend due to the tolerances which are impressive =P. The final plunge as to where to make the bends was a good percentage of guesswork. Also rather than have two stanchions at the very back corners (as in the plans), we'd seen other builders bringing them forward a few mil which allows the bend to flow into them better.


(https://www.modelboatmayhemimages.co.uk/images/2019/07/20/41.jpg)


One point that has required a bit of thought is the curved front of the main structure. After spending a good week trying to soften up the piece (clamping it to the model, clamping it to a paint tin, steaming it, bending it as much as we dared, offering it cash) the edges where it marries up to the sides of the cabin didn't look at all like they would hold.


(https://www.modelboatmayhemimages.co.uk/images/2019/07/20/42a.jpg)


The sweep of the deck was too much strain on the piece. Tip our hats to those builders who managed this as designed.


(https://www.modelboatmayhemimages.co.uk/images/2019/07/20/43a.jpg)


Tried cutting out the same shape from a thin plastic binder cover but we weren't happy with that. The flexibility was there but the meeting of the end joints was pants...


Solution: Shallow out the deck curve. Layered and shaped a chunk of MDF to bond the piece to properly.


(https://www.modelboatmayhemimages.co.uk/images/2019/07/20/44.jpg)


The MDF needs a little more work to make everything flush. The section of the removed forward deck shows the original curve versus our modified one. XD

Just a point of question, is that replacement shaped MDF former heavy? and will you paint the exposed surfaces?.......


Some MDF material + water moisture causes severe  <*< swelling of the MDF

Post by: Phil22 on July 20, 2019, 08:40:01 AM
Thanks very much Derek. The MDF piece doesn't have much weight to it at all. It's comparable to a piece of balsa the same size. To keep the weight down though, it'll get hollowed out with the dremel a touch. The MDF has received coats of wood glue during shaping and when ready it'll get a few coats of primer before painting. This should seal it up enough  ;)

Our tug is starting to look more like the box =) The wooden parts have been really enjoyable to put together. While the instructions could be a whole lot better, it is definitely rewarding to think carefully about each step and work out what needs doing.
 
This probably won’t be of use to most but on the offhand here are the local (Tokyo) materials we are using.
 
Tin = Undercoat
Bottle = Quick drying wood glue (Excellent stuff)
Box = 2 Part epoxy as recommended by Sugi-san (check out his Banckert on Youtube). Goes off in around 30 minutes but needs 24hrs to cure. Dries clear.
(https://www.modelboatmayhemimages.co.uk/images/2019/07/28/45.jpg)
 
The epoxy did a great job of maintaining the bend in the stiff plywood. Fashioned a small ply form and left it clamped for 48 hrs.
(https://www.modelboatmayhemimages.co.uk/images/2019/07/28/46.jpg)


Worked on the basic shell of the rear cabin. As early on we removed the bevel from the bridge floor, the fit is a little out, meaning the rear cabin sits a touch high. This will be an easy fix in simply putting the bridge on a new 3mm base.
(https://www.modelboatmayhemimages.co.uk/images/2019/07/28/47.jpg)
 
(https://www.modelboatmayhemimages.co.uk/images/2019/07/28/48.jpg)
 
 
All the wooden fittings that make up the funnel and main mast sections shaped, sanded and ready to assemble.
(https://www.modelboatmayhemimages.co.uk/images/2019/07/28/49.jpg)
 
 
There is a vent at the base of the funnel which we couldn’t identify at all in the kit. It looks like a part is stuck on over the plywood. Looking online either people have gone with plain wood or got creative. We chose creative and built in louvered fins using the fitment beading.

 (https://www.modelboatmayhemimages.co.uk/images/2019/07/28/53.jpg)
 
 
Also, there are areas on 3 sides of the funnel in the plans that receive parts (vents). Same issue, couldn’t identify so repeated as above, this time with toothpicks.

Title: Billings Banckert 516 - LED help request
Post by: Phil22 on August 04, 2019, 01:12:08 PM
Being our first build, we made the decision early on not to put in freeing ports going on the assumption that if it is that choppy, we'd not sail that day. In the standard Banckert kit, the rear deck has no coaming. So we've opted to build up the rear deck cover a few mil and add in some coaming for a bit of a safety margin. The rear deck definitely does look better flush but we'll go with caution this time. Perhaps we'll achieve this (and freeing ports) with a future build after acquiring more experience.   

Reworked rear deck cover. This is the first piece to receive some wood filler - still needs sanding flat.

The contact point for the main mast is less than 8mm square. Envisioning the day when it gets knocked and breaks prompted the use of a dowl "bamboo toothpic" (very strong). These are also excellent for accurately applying glue.

Prepped 2 initial holes in the funnel for LED wiring

OK hands-up, we are approaching a part that we literally have no experience with. Basic electronics =P. We would really appreciate some help in creating something like either setup below. Thinking to base off a 9V battery, would this work?

2 navigation LEDs, 1 internal bridge LED, 2 LEDs on the V bracket (funnel section) *all LEDs 3mm

Idea A

A chain of 5 white LEDs connected to an on/off switch, a fuse and a battery. Coat 2 LEDs with marker pens (1 green, 1 red) for the navigation lights.

Idea B

1 red LED, 1 green LED and 3 white LEDs connected to an on/off switch, a fuse and a battery. This would be a parallel circuit (we think...). Google mentions different colours of LED require different voltages so with understand 3 different resistor types may be needed.

We've had a go (don't laugh) at producing some circuit diagrams to try and explain

Might want to feed the three white led's in parallel too, with dropping resistors for each- makes it easier to fault find if one goes duff.

Thanks a lot Subculture! That was another of the questions we had.
Regarding the gauge of wire. What would be the thinnest (recommended) option for this simple setup?
Title: Re: Our First Build - Billings Banckert 516
Post by: Subculture on August 06, 2019, 08:54:06 PM
Small  low power LED's only draw 10-20ma at most, so really the finest wire is suitable e.g. 0.1mm2  would be perfectly okay, and can be hidden by slotting masts etc.

Work on the bridge has progressed a little this week. It looks like the plans have the bridge's ceiling extending out on three sides. We've seen other builders getting the sides flush which we think looks better, so went for this approach.

  (https://www.modelboatmayhemimages.co.uk/images/2019/09/01/70.jpg)


As we took the bevel off the bridge's deck early in the build, to get to the kit fitting correctly again we added a new base trim.

The bridge roof section has a high 'faff level'.

  (https://www.modelboatmayhemimages.co.uk/images/2019/09/01/72.jpg)

Decided to build it off the model having made an outline on a plastic sheet. Didn't fancy trying to glaze this part from the inside either.
Used a couple of other parts to raise the piece up around 6mm. Taping it all down then gave us the ability to slide in the side sections and get them glued. These thin window sections won't take much of a chamfer as there isn't much material around the sills.

The upper window section has been the most challenging part of the build so far. The plans are far too general.

Not sure which species of wood is used for the heavily curved parts but the fact that grain runs vertically (at least in our kit), so far 2 of 5 parts (1mm thick) have snapped while coaxing them into the shape required. Last pic: part A snapped and was unsalvageable, part B snapped and was rescued, mostly thanks to the wood filler.

This has been the only real disappointment with the kit. The other plywood parts have largely been great to work with.

Coming along nicely.  And I guess we have all found parts in kits which were only suitable for the bin. If we are lucky they are straightforward to reproduce from our own materials. You seem to be coping well with the occasional rogue, and the whole boat is looking good. Well done.   :-)) :-))

Dry wood will only bend so far.  Usual practice in modelling circles is to soak, or steam and set in place.  I don't think the destructions are necessarily at fault for not saying that because it's such a common thig to do when working with wooden parts in models.  But in your case I would probably have done the same thing -and just used polystyrene instead!  I guess that sounds a bit hard though!  It looks a brilliant biuld though.  A Bankert has been taunting me in my local shop for ages, not for best part of £300 though!

£300 for the kit only or for a full build price? FYI Kitstop (Address: 20 Oxton Rd, Birkenhead CH41 2QJ, UK) quoted me £180 for the kit.

Progress since the last comment has mostly involved filling and sanding. From last year I started collecting useful Banckert build images which have been invaluable so far. The range of detailing ideas from various modelers is great to see.

Work has continued on the handrails and this time we’ve had some good results with the slow drying epoxy over solder.

The front of the bridge in official pics has a rounded section front-center not shown in the instructions.

First off roughly cut the rails to size, measured out the distance between stanchions on a board (we tried 32mm to allow for the radius bend later).

(https://www.modelboatmayhemimages.co.uk/images/2019/10/09/91b.jpg)
 
Trimmed and filed off the excess material then moved the handrails back and forth the draw the epoxy into the stanchions. 

Propped the piece up with a square while drying. Used a crank handle to bend the piece around then prepped light pilot holes in the plywood.


(https://www.modelboatmayhemimages.co.uk/images/2019/10/09/92.jpg)


Moving onto the side rails followed the same process this time over two days to give the epoxy time to go off before working on the opposite ends.


(https://www.modelboatmayhemimages.co.uk/images/2019/10/09/90.jpg)


(https://www.modelboatmayhemimages.co.uk/images/2019/10/09/93a.png)


(https://www.modelboatmayhemimages.co.uk/images/2019/10/09/94b.png)


So far they’ve stood up well to the forces exerted while bending into shape. This approach has been much easier / neater than first making holes in the plywood THEN getting each section to fit.

Found that chopping a little off the larger stanchions stops them from bending when being tickled with the hammer. (Same length as the shorter ones works best)


(https://www.modelboatmayhemimages.co.uk/images/2019/10/09/95.jpg)

The epoxy approach when putting together the railing sections has proved much easier for us than using solder.

For our build we wanted something a little unique, we extended the rear cabin a touch to create a (theoretical) platform to access to the funnel mounted ladder.

Steady work on the handrails has continued over this past week. They’re almost done bar buttoning up a few small areas.  Daunting at first, but with thought and some trial and error we are happy with the results for a first effort.  We’ve picked up a few new skills and tips along the way ; )


Port and starboard handrails from the deck to the bridge


(https://www.modelboatmayhemimages.co.uk/images/2019/10/27/112.jpg)


(https://www.modelboatmayhemimages.co.uk/images/2019/10/27/113.jpg)


A cutting mat provides a great visual aid when putting bends in the required spots


(https://www.modelboatmayhemimages.co.uk/images/2019/10/27/114.jpg)


The ladder is supported by a small piece of ply under the top step - helpful during mockup as for each rail there is only one point of contact at the stanchion


(https://www.modelboatmayhemimages.co.uk/images/2019/10/27/115.jpg)


As not to have open joints on the stanchions these extra details were fitted


(https://www.modelboatmayhemimages.co.uk/images/2019/10/27/116.jpg)


The full set of brass parts


(https://www.modelboatmayhemimages.co.uk/images/2019/10/27/118.jpg)


The instructions have the rails of this section (left side) going into the rear cabin wall. For ease of fitting and for something different we made them this way (right side - pre-trimmed 'P' shaped part)

The intention so far was to go with a brushless motor (like this: https://hobbyking.com/en_us/turnigy-aerodrive-dst-700-brushless-outrunner-motor-700kv.html?___store=en_us (https://hobbyking.com/en_us/turnigy-aerodrive-dst-700-brushless-outrunner-motor-700kv.html?___store=en_us)) but I’ve since read that brushless struggle a bit a low revs. Would a brushed motor be more suited for this build?

I’ve since read that brushless struggle a bit a low revs. Not wishing to build a speed-tug, would a brushed motor be more suited for this build?

They're referring to cogging at very low rpm, which applies to sensorless set-ups. This is pretty much eliminated on modern brushless esc's.

On a boat this makes little to no difference, as the prop is essentially a fluid clutch e.g. it slips. Cogging can cause issues on model cars that like to run slow e.g. rock crawlers, where lots of torque is required and lots of sensitivity at low throttle settings.

In short I wouldn't let it concern you.

Whilst on the subject of epoxy, I find a coat of epoxy resin on wooden parts, mixed with a little bit of talcum powder, seals and strengthens everything beautifully before priming. Once the epoxy is lightly cut back (the talcum powder is optional but helps the sanding), it seals and smooths the grain giving a smooth surface more like the plastic parts
Title: Re: Our First Build - Billings Banckert 516
Post by: JimG on October 27, 2019, 08:44:01 PM
Instead of talcum powder I use Microballoons, costs more but I find it sands better and gives a really good finish. (won't smell as good when sanding though)

Post by: Subculture on October 27, 2019, 09:32:12 PM
I once used some microballoons as a substitute for fumed silica when thickening some epoxy to use as a gelcoat- that was an experiment, but a big mistake. When I was post finishing the mould I ended up with lots of tiny pock marks, which I believe were the microballoons so I only tend to use them for areas which won't be sanded back.
Title: Re: Our First Build - Billings Banckert 516
Post by: JimG on October 28, 2019, 10:20:36 AM
Sounds like you were using a lot more microballoons than I would use to seal and fill the surface of wood. Some of the earlier microballoons (especially the brown phenolic type) were larger than those available today (the white type seem to be very small) so could have lead to a pock marked surface. When I have used them to produce a sanding sealer only a small quantity was needed as they are there to fill the grain of the wood not to give a thick layer. When sanded I have not seen any pock marks on the surface, with the surface  ending up as smooth as styrene sheet.

If you could see the pock marks with the naked eye then it was probably air bubbles in the mixture.  Microballoons are, as the name implies, very small indeed and you cannot distinguish them in the epoxy matrix.  However they do stiffen the mixture, which makes it a lot harder to get air bubbles out, so you need to be quite gentle mixing them in.  But they do make sanding so much easier, and with care and good luck you can get a baby's bum finish as witnessed by Jim.

Any excess epoxy on the handrails easily came off with a scrape from a craft knife, while leaving the joint intact. There are 5 or 6 more details to go on for the rigging then its on to hull strengthening and prep for the electronics.

Wasn’t air. The little marks showed once I compounded the tools. Only the part of the tool which had the micro balloons showed the marks. On something that is going to be painted it’s no big deal, but this was a tool to mould from. It was still usable, but I made a mental note not to use microballoons for that purpose.

Well, we thought the brass bits were all wrapped up. Not quite, but it’s okay as they’ve turned out to be real fun to make.

The last parts (watch this space….) are for the mast rigging. Puzzling on how best to attach the lines, a few ideas were tried out including creating various hooks and looping the wire back on itself. None of which looked particularly neat. Finally we settled on chopping up unused stanchions and soldering the trimmed hole sections to the ends.

To stop the nano-bits from moving about while soldering they where each threaded onto some spare wire then taped down like so.

After 3 months away from the build and out of winter hibernation, the Banckert has officially been pulled back out from under the bed. Game on!

First off, I put together a list of everything that still needs doing (that I’m aware of). This I’m sure, will fall into some kind of clearer order as the work continues. Secondly, I took stock of the remaining unassembled and unused parts. It is starting to look more like the box - on the outside ; P

Been working on the wooden deck rails and moorings this week. Some tapering of the bollards is required to allow for vertical fitment against the hull.

For the curved pieces, we tried lightly scoring the underside of the rails then applied a coat of wood glue.

(https://www.modelboatmayhemimages.co.uk/images/2020/03/15/DSCN2520.jpg)

This seemed to work ok but the scores are kinda visible and not sure on their durability. Previously other members have mentioned heating or soaking. What are some recommended processes to setup for each approach?

Title: Re: Our First Build - Billings Banckert 516
Post by: SailorGreg on March 15, 2020, 10:33:04 PM
The scores can probably be filled with a small amount of wood filler and if your glue is good then the curved bits should be as durable as the rest of the rail.

However, if you want to try something else, you can steam small pieces like this in a microwave.  Wrap the piece in a few layers of kitchen towel then soak in water. Pop it into an unsealed plastic bag and put it in the microwave for 2 minutes. Take it out (it will be HOT - wear gloves) and push into place and clamp it there until dry/cool.  The grain will have been raised a bit but some gentle sanding will get rid of that.

Another alternative is to laminate several layers of veneer.  Make up a blank with the same profile as the rail and cut as many strips of veneer as it takes to build up the right thickness.  Lay them in place with glue, clamp down and leave to dry.

I still think this is an outstanding first build.

Hi All,

We'd really appreciate the help of the forum members with guidance on the stuffing tube and prop setup. Looking around we've not yet found many answers as we are still in fact unsure of the questions. We understand that all builds are unique and have their own requirements. I think what we are needing is a crash/sink course (hopefully not lol) in what is what.

The Banckert kit contains:

- Brass stuffing tube 98mm x 6mm (5mm inside diameter) x 1
- Brass prop shaft 135mm x 3.5mm diameter (3mm thread diameter - 10mm of thread) x 1
- Brass nut x 1
- Plastic prop x 1 (not intending to use)

:: Stuffing Tube - Propeller Shaft ::

We want to put in a 40mm brass prop (4 blade), the one we've seen online here in Tokyo has a 4mm (M4) thread.

- Is the kit's stuffing tube 98mm x 6mm (5mm inside dim) suitable to take a prop shaft connected to a 4mm prop?
- Is there a minimum gap or internal clearance needed within the stuffing tube and the prop shaft?
- Should the stuffing tube be any longer?


:: O-rings :: Warning REAL NEWBIE Q's here

- (Hesitate to ask this one) Are they required on both ends of the prop shaft?
          Does the nut next to the prop work with the grease to stop water ingress?

- Where are o-rings placed and how are they kept in place?

:: Play ::


I've read various things about play in the prop shaft. Some articles say a bit is needed, others warn of it as the prop hull or both may be damaged especially when reversing.

The hull is still intact, we'll keep it this way until we are certain we know how to proceed on with this area.

Unsure of the name of this part below. It has a 6mm internal diameter

The skeg (right terminology??) is around 5mm wide at the point where the stuffing tube should exit.

There's a lot in this post and probably the most crucial thing to get right. Your experience on how to tackle this part of the build would be sincerely welcome.

Thank you for any info or advice shared.

The first thing to discuss is that there don't appear to be any bearings in the end of the stuffing tube.  Your shaft is clearly smaller than the internal diameter of the tube, so you need a bearing at each end of the tube.  If you haven't already done so, can you search through your fittings and see if there are two brass/bronze collars that look like they would be a tight push fit in each end of the tube and are a snug fit around the shaft?  If you try and fit things as they stand you will end up with a very noisy, leaky arrangement (o-rings notwithstanding).  If you cannot find any bearings, I suggest you buy a ready made tube with bearings included (which will almost certainly include a new shaft, but that's better than no bearings at all).  There are plenty available on the internet, such as these (https://www.cornwallmodelboats.co.uk/acatalog/Caldercraft-Standard-4mm-Thread-Prop-Shafts-M4.html).

On the subject of o-rings - no, you don't need them.  Assuming you get some bearings of the right size in each end of the tube, a little bit of waterproof grease will see you home and dry (!).  You could usefully put a brass washer between the locking nut and the end of the tube, and similarly on the inboard end for when you run in reverse.

Play in the propshaft - you need a tiny bit of play, enough that when you push and pull you can feel there is a little movement, but not so much that you can actually see it move.  You are looking for as tight a fit as you can without there being any binding as the shaft rotates.

And this hardware should be fine with a 40mm prop.  If you get the bearings in place.

Hope that all helps.

Greg

HI
There should be 2 brass/bronze collars looking like that one in this photo (Taken from my fittings bag for Banckert) the shall be pressed into the tube.

Our huge thanks to @SailorGreg and @tica

The info which you both shared has helped in our understanding enormously!!!! You've also raised our confidence with this aspect of the build.

As you mentioned Greg and as Carsten pointed out in the photo, those 2 bearings are present in the kit for the stuffing tube. We had no idea as there are many little brass details not listed in the manual. All good now ; )

For the prop-shaft requiring a tiny bit of play. I image this could be something we can hear more than see when assembling the components. A kind of small "knock" maybe?

Now that we understand more about what is what, we are thinking to go with a smaller size (M3) prop and use the kit's parts unless we can find a brass 4 blade (38~40mm) on a 3mm thread.


Thank you again you've really helped a lot.

Regarding the propeller, Prop Shop (https://www.prop-shop.co.uk/products.php?cat=standard-scale) do a huge range, but their standard threads are M2 or M4.  However, if you are really keen, they will probably do you a one-off with a M3 thread.

I first thought, M3, you'll be lucky but Cornwall model boats stock plenty of M3 props, including those for a kort nozzle, from Raboesh etc. If your prop tube (no American terminology) is 6mm OD though I would personally recommend changing to M4 slimline and fitting the built-in oiler/greasing point also.

The microwave wood bending tip from SailorGreg is working well. Should have the handrails wrapped soon. Thank you to Greg and Rich for the links and pointers.

Here are a few progress shots.

Added 5mm of combing to the access hatch. This went together really smoothly as cutting the long pieces on the proud side allowed for the model to cut into the ends, effectively locking them in place. They'll get some kind of protective coat before gluing them.

To the underside of the hatch we fit these five grabs.

Two of the rope guides are in. The one on the stern still needs a mounting point

We've worked on a few things since the last post. Used up more of the bits from the supplied fittings kit.

The winch is assembled. Trimmed down the levers a touch.

It was the the first time to try out Tamiya Epoxy Putty, found it to be excellent. Watched a few YouTube vids and a top tip is keep your hands wet when rolling and forming it into shape. Dries out great and then easy to file/sand. Used here to fix the tow rope guide to its wooden base.

Some lighting shots. Still in two minds on the best way to approach this. Probably practice with a few more circuit designs before deciding.

Decided to try our hand at laying a wooden deck. Created templates then used strips of 2mm x 5mm.

Used some graphite to darken one edge of each piece for contrast. (Photo shows a test piece with both edges darkened. The effect was too heavy - one edge only looks better!)

My girlfriend made an absolutely cracking job of the forward deck.

Can move on to shaping tomorrow.

We finished up shaping the deck sections this week. Initially the idea was to have the superstructure sit in various cutouts in the sections, remaining in contact with the plastic from where all of the measurements/fitment have been made so far. It half worked but did leave some gaps that kept catching the eye. This led to some reworking to now have the superstructure and rear hatch resting on the new deck. All the bits will get epoxied down later on after coats of stain and varnish.

Today began trimming the hull down to match up with the deck.

She looks a treat Phil and Co  :-)) The cardboard template idea is good but I recommend that if retained, you seal it well against moisture to prevent expansion and warping.

Hello Phil. Pleased to find this thread on coming back to the forum after some time. As I am probably locked down for months due to my missus being highly vulnerable, I went up in the loft and dug out all my half-finished and yet-to-start projects. One of these is my Billings Banckert, which as far as I can work out I actually started somewhere around 1985!! I got it complete except for  some detailing and had it powered up and on the water with a 27 MHz set. For a variety of reasons it has been  consigned to the loft for years, until the start of the lockdown. It took a helluva lot of cleaning!
I have kept the old 6v Monoperm motor with the original prop as it worked very well on the water. I am replacing the r/c with a modern 2.4GHz set, new battery pack obviously, and a solid state speed controller to replace the old resistance unit. I have had to get the old stuff out through the top deck cutouts, which has been a bit of a job, but the new stuff is all smaller and easier to get in.
I have only had a relatively small amount of detailing to do, masts and aerials, top deck railings and fittings, etc., but all I have to work from is the drawing and two photos that I cut from the original box. I see from your photos that you have started the railings from the top, can I just offer a couple of observations?
 The pipes to the fire monitors are a right pig because they have to be bent in three planes, and you have to make the port one a mirror image of the starboard one, which is easier said than done. On mine , part of the monitor-deck railings had to be cut away for the pipes to go through, and I also found it very difficult to get their entries into the base of the funnel evenly lined up.. What probably made things worse was the 25-year -plus gap between making the port one and making the starboard one!
 Hopefully your instructions will remind you, but don't forget to fit the access rungs onto the deckhouse side that go from adjacent to the wheelhouse doors up to the deck in front of the funnel - BEFORE you fit the other railings. I didn't realise I had missed them till all the railings were fixed in place, which makes it very, very difficult to fit them , and that's what I am currently struggling with.
  I'm looking forward to following your build. I think your modelling standards are probably higher than mine, which makes me a bit embarrassed to attach photos, but what the hell, mine will be the best I can manage. And I think I might be able to stake a claim for the longest time to complete a model! :-)

Thanks very much for your help @ballastanksian and @SteveH, really appreciate the advice from yourselves and this brilliant forum.

Bought some wood stain for the decking, going to see how that turns out today. The wood will get sealed with clear varnish top and bottom before being epoxied to the ABS. There is some undulation (by design) in the ABS, need to buy more clamps for the task.

"And I think I might be able to stake a claim for the longest time to complete a model! :-)" LOOOL, thank you for sharing your experience Steve, would be great to see photos of your Banckert. Noted your recommendation on access rungs, cheers. Our superstructure parts aren't yet connected so access is still OK. Due to making the small platform to the funnel mounted ladder, there is about a 5-rung offcut which might get used for the deckhouse ladder. About the pipes to the fire-monitors, while not true to the build, we decided to leave them out pretty early on. I did have a go but like you said they are a pig. Skill limit met. Maybe I'll have another go down the line. BTW PM me if you need any more reference info.

RE: Vents on the funnel, I owe Billing's an apology. Previously, we could not find the parts for the funnel vents at all. The other day I spotted them on the decals sheet.... ;)
Also the thread on the supplied propshaft is M4 (not M3). Now verified with an M4 bolt.

Bilge keel question.
The clip below is of a superb Banckert build by a Japanese modeler. His bilge keel placement we guess looks on the money from what we have read which is:

- length around 1/3 of the hull
- positioned 45 degrees from their mounting points on the hull
- they need to be above the hull's baseline

Bilge keel shot at (02:54) https://www.youtube.com/watch?v=ImoP06JkoA8

Would appreciate any information on tackling these. Thanks in advance.
