Title: Another Slo-Mo !
Post by: Hagar on August 25, 2008, 07:02:24 PM
Well I bit the bullet and made a choice. My first build is going to be a Slo-Mo-Shun thingie! BUT just because I'm like what I am, Its going to be from scratch. And if I did me sums right in 1/8 scale!!!
So. To get things started, I needed a plan. This was duly found and the maths done and a new plan printed out. Due to the resulting size of the model, this left me with a pile or A4 pages that had to be sorted out. That done the paper patterns where transfered over to thickish card, and cut out. These in turn were set up on a chunk of 6mm birch ply and chopped out into the rough shapes. As they get cut to size, sanded and trimmed, they get placed on the build board. Just come in from doing nr, 3 and 4. The bow and the second one being done yesterday, after I built the board.

Now for a few questions:
How do you post photos here and what is the preferred size? Once I got that figured out I'll be posting a few pixes of the build as it grows from a bit of plywood to a hopefully beautiful boat.

One thing to set down first is that it will be first and formost a statice model but there will be a motor and radio going in her. More on that later, but a few points arise from this wish.
I was thinking of doing the bottom in alu. as she was built. In an attempt to save a bit of weight, would it be prudent to skip the bottom planking, or sheeting in this case, and glue the alu direct onto the hulls ribs? Maybe a better idea to clad the bottom just like the real one? Does any body, some of you on the other side of the pond maybe, have access to pictures of the bottom? My searches on the net has found a good deal of top side photos, but none of the bottom.
Any good suggestions on which type of glue to fix alu to wood with. Aralldit?

Like I have said, this is my first build, so be kind.

I have read pretty much all the master build posts, (and have infact ordered a set of plans for the 63ft rescue boat that Bluebird is doing such a great job on).

Also if any one that has built a Slo-Mo is more than welcome to send me a message to let me know who I can rib for dimensions of some of the things I have no idea about!!

Cheers!

Found a pretty great gallery, with boatloads  ::) of photos of Slo-mo IV. masses of detail pics too.

I noticed that the port side of the rear section, is straight, but the starboard side has a long curved section that comes up to the water line. Any one got a take on that?
I se that the rear bulkhead of the sponsens has also a large round opening (a hole). Having now seen this I took another look at some of the other phots I have found to see if this was also a feature of the boat when running, It is! Anyone got any suggestions as to why this hole is there?

One last question: Has Slo-mo been one to death?

Well  thus far I have printed the plans for the ribs, cut them in 6mm birch ply and as of today, covered the top with 1,5mm birch ply.
Had a nasty moment when it came to cutting the opening for the cockpit and motor compartment.

Here are a few photos:
Take a pile of cardboard, and cut the paterns for the ribs:
(http://img.photobucket.com/albums/v462/IanM2760/Boats/slo-mo-1web.jpg)

Cut them out of ply and fix to a build board:
(http://img.photobucket.com/albums/v462/IanM2760/Boats/slo-mo-2web.jpg)

Get some ribs on, make note to buy more clamps:

Post by: Hagar on September 03, 2008, 09:44:12 PM
Once the glue has cured, the under decking can go on, Being a coward, I opted to do it in four parts, as I just could not figure out how to di it in one piece:
(http://img.photobucket.com/albums/v462/IanM2760/Boats/slo-mo-7web.jpg)

So far so good:
(http://img.photobucket.com/albums/v462/IanM2760/Boats/slo-mo-13web.jpg)

Now there are a few pictures missing as my telephone was recharging...
Now the top is skined and ready for a bit of filler and a sand paper rubdown.

Had a bit of fun making a prop shaft for it. My new shaft is 4mm Piano wire. which was actually 4.1mm. Not nice when the hole in the bearing is 4mm. After a bit of spinning in some emmery, is went in with out to much violence.

Now I just have to cut it to lenght and thread the end.
Title: Re: Oh no! Another Slo-Mo !
Post by: Hagar on September 04, 2008, 10:09:47 PM
Well things are going along nicely, well I think so.

There is now a hole in my boat, Fortunatly it's in the right place... Hopefullly:
(http://img.photobucket.com/albums/v462/IanM2760/Boats/slo-mo-14web.jpg)

Also got the hull cut away from the building board. That was hard work!
(http://img.photobucket.com/albums/v462/IanM2760/Boats/slo-mo-15web.jpg)

This now enables me to shape the bottom stringers to make the bottom.

Nice looking build mate a guy i met at the local lake has one with a zen in it,its from an old dumas kit he bought in the states years ago.Been a true scale model it doesnt run great its fast but turns are very poor he reckons.Def not as fast or agile as my semi scale rockett hydro.Heres a  pic of his shes a nice boat ,keep up the good work.

Post by: Hagar on September 13, 2008, 05:14:35 PM
Thanks for that Martin, begining to think that no one was looking!
Do you have that link I sent to you to that gallery with all those photos. My PC is dead and I'm on the misseseses at the moment. Most inconveinent as all my plans and what not are on mine!
Story so far is that the hull is skined in ply, and is getting near the point of the mahogany planking.
Got the tail fin sorted, I had printed the pattern for that, Now waiting for the glue to dry....

Still a bit stumped as to fixing the aluminium on the bottom and transom. Any body with ant advise?
If some one could advise me as to an aproximate size for a stearing wheel would also be helpful. Either the size of the billing boats one or the real one, the I can size it up to 1/8.

One last question for now. Alu speedboad rudders, any good suggestions to a web shop for those? I can find loads in plastic.

More photos later, got to find a cable, mrs pc dont have a bluetooth port!
Title: Re: Oh no! Another Slo-Mo !
Post by: martno1fan on September 13, 2008, 05:46:45 PM
Which gallery mate?,as for rudders i dont know because you will be wanting a scale one ?.try this guy for decals he will cut some realistic ones the correct size hes a top guy.He will also know where to get the steering wheel and his prices are good.

Post by: martno1fan on September 13, 2008, 06:26:10 PM


the sloping side at the rear is called a non trip side i have two on mine they are to stop the boat tripping over itself in a  turn as the boat turns water shoots up the angled non trip rather than hitting a flat side which would slow you down and also maybe cause a flip.Yours has one i asume because its meant to turn right only.

Thanks Martno. Now I think about it I think it was Mark I sent that link to with the gallery. But what the hey. It was in the link you sent so luck played out.
Thanks for the link to the guy with the decals too. I have a pile of waterside paper, so I was thinking of doing them my self to, but after I have  >>:-( and :'( and  >>:-( some more I might just drop him a line!
Title: Re: Another Slo-Mo !
Post by: martno1fan on September 14, 2008, 01:44:20 PM
No worries mate Jim who makes those decals is a nice guy and he can make anything you want and you couldnt beat his prices here and shipping at a guess will be arround £4 -£6  thats all it cost me for a 2 ft tube full of decals last time i had some delivered from the states.Back to your build what power plant are you planning for it ?.I you plan on running her id consider a slightly oversised rudder as they seem to have a very wide turning circle been scale they dont seem to scale down and run that well at least the one i mentiond earlier doesnt according to the owner.Just something to be aware of if you plan on running it fast as id hate to see you run it up the bank and ruin your great work ;).

In my neck of the woods, in Denmark, there are very few places you can run a gas boat, so I am thinking brushless. Not 100% on that though. I rather like the idea of a gas motor. (If money grew on trees I'd drop on of those v8's into it. Why? cause on one makes a V12 {-) ).
As for the size of the motor to put in it I am totally clueless! Its 104cm long, about 35-40cm wide (I think, cant be chuffed to go out and measure it). Weight wise, no idea as half of it is laying om the bench, waiting to be made or stuck on.

I've made a start on the planking, so its going along. but no pictures yet. I've taken a few, just cant post them yet as I cant get them off my phone onto the PC.
Title: Re: Another Slo-Mo !
Post by: martno1fan on September 15, 2008, 10:26:39 PM
You could shoehorn a stock 260 zenoah or maybe a 230 zen rather than a 260 would be better.Or go nitro maybe?.Sounds about the same size as the one in the pics,he has a modded zen in his but its over powered and struggles to turn mind you it struggles at half speed too.Electric sounds a good idea if noise is an issue but i have no clue with those lol.

Nice turn of speed there martno. Personally I have no objection to a bit of motor sound, but unfortunatly there are not a lot of places I can run a IC motor boat here.
The Slo-mo pictures that you posted; was that built from a kit?
Thunderboats is a pretty good site, but the join up page is down at the moment. Slomoshun.com is still rather incompleat, and I still need to get some info - photos of a good few things yet, also some further info.
Like was the rudder on the tail fin, conected to the rudder, or was it controlled seperatly? I've seen it refered to as a trimer, so maybe not connected to the rudder. The Actual profil of the tail is simple enogh to figure out, but the section is a bit blurry. Looks like the bottom gets thicker at the back end, but the top is thin all the way frount to back....

If you can think of any other good sourses for Slo-mo stuff, prey tell.

Post by: martno1fan on September 20, 2008, 02:49:57 PM
Hi mate yes the slo mo was a dumas kit very rare nowadays,probably worth some money now.Dont know why he runs it id have it on display,it doesnt handle great (doesnt turn well) according to him although ive only seen it run on video.I will keep an eye out for info for you mate.

Try this site mate,look for a guy called Dave Weagle he knows lots about these boats hes a mate of mine shoot him a pm im sure he can help hes seen most of these boats in real life,the full size ones i mean.Hes built quite a few himself from scratch and from kits hes more into scale ones than me and knows his stuff.

Post by: Hagar on September 28, 2008, 07:20:34 PM
Latest up date:
The top is now planked with mahogani, Rough sanded and looking OK if I say so myself. Pictures to follow. Just got to figure a way of getting them onto the pc....
Tail fin is also done, and the trim rudder attached.
Started on the motor cover. This is the worst part for me, as the only real guide I have is photos on the internet. It looks a bit wiered at the moment, but then its only halv done.

Still being a bit of a coward about clading the Alu onto the bottom and sides...

Getting to think of details. Like do I paont it as a slo-mo. or do I paint it a bit different and just call it a three point hydroplan? Hm....

Mart,
On the real boat; the motor cover, was that made of aluminium or wood? The one I did in wood looks like, er.... not that great, shall we just say! Think that its a do over!

Been trying to find some info on the net but not to much around on that part of the boat. Looks like it might be metal, with all the rivets on it. Logic says that a wooden one would be a bit impractical. Any views on that?

I am at the moment e-mailing the photos on my phonr to SHMBO's PC. So might have some thing in a few days I can post!!!
Title: Re: Another Slo-Mo !
Post by: martno1fan on September 29, 2008, 06:42:31 PM
Hi mate i can find out for you,let me know any more info you need as i know a guy in the states who knows all about these boats ,in fact he knew Roger Newton i believe who as you know was very involved in not only working on the real hydros years back but rebuilt a few for the hydro museum,he was also the man that brought these boats to rc for the first time.My thinking is as yours that the cover and canopy was probably metal of some kind.

Right then! After a bit of fiddleing with the old e-mail accounts I got some photos off the phone and onto the PC, them on Photobucket. Phew!

A start to the planking. Seems as good a place as any to start:
(http://img.photobucket.com/albums/v462/IanM2760/Boats/20092008082.jpg)

Then a bit more:
(http://img.photobucket.com/albums/v462/IanM2760/Boats/23092008086.jpg)
Just wipede the front off with a damp cloth to get the dust off.
One side down one to go. I did think about the 5 a side rule then thought Naaaa, go for it!

All of a sudden (like after a week and a few days) the top was done. Just needs a good sanding down. (yawn).
(http://img.photobucket.com/albums/v462/IanM2760/Boats/29092008090.jpg)

The tiny inconspicuos tail finn is just sitting there at the moment, cant make up my mind as to glue it or screw it so it can come off for transport...
(http://img.photobucket.com/albums/v462/IanM2760/Boats/29092008092.jpg)


A quick step back to have a look at things. The scaffold in the motor bay was the first attempt at building the motor cover. Failed with flying colours I might add!
(http://img.photobucket.com/albums/v462/IanM2760/Boats/29092008089.jpg)

Thanks for asking, mart. As it happens I could really use an idea of the size of the steering wheel and maybe a good picture of the dashboard. Metal does seem the most logical, just got to get my head around the nosecone for it. Im off to the museum gallery!
Title: Re: Another Slo-Mo !
Post by: martno1fan on September 29, 2008, 09:14:29 PM
Its looking really nice mate top job i think you can still squeeze some floatation in there? cut some pool noodles to fit where you can.As soon as i get info on the cover ill let you know ill also ask for some dash photos if he hasnt any they dont exist lol.

Wow that was quick he got back to me he says he thinks they were glass fibre and used metal straps and rivets to join them,he says none of the cowls looked dented on the orriginals so they must have been glass fibre.Theres some great pics of the slo mo shun dash on the museum site heres a link to some.

Found a yard of closed cell pipe insulation which I managed to get into most of the bow and sponsens, so hopefully it wont go straight to the bottom when it sinks. (theres confidence for you)!

Post by: boatmadman on September 30, 2008, 09:31:18 AM
Hi,

Looking very nice. I saw you wiped the wood with a damp cloth, I would recommend not to do that, it raises the grain of the wood and will need more sanding.

Use white spirit on a cloth, it cleans, degreases and de dusts all at the same time.

Boat mad: Its not sanded fine yet, Had just ripped the top down to get rid of some glue ouse and the excess cardboard from between the planks. But thanks for the tip. My old wood shop teacher said that if you dampen the wood to raise the grain, then sand it, when it drys again it will be like a babies bum. Fair enough, but he said nowt on how to stop it smelling!

A tip from a guy I know suggests using West pack epoxy to fix the Aluminium on the bottom/sides. Any one got any experiance with that?

PS Hemple do a clear to pak varnish "Diamond" anybody tried it. Said to be glass clear. UV resistant and hard as nails. Thinking of using it ot finnish off with.
Title: Re: Another Slo-Mo !
Post by: Hagar on October 03, 2008, 01:54:18 PM
Right then! Things are getting interesting...
Motors, This boat started out as a dislpay build, but you all now how these ideas end up {-)
If I wanted to get any form of speed out of this thing, what size of motor should I be thinking of. I know I should of had that sorted before I threw it together, but like I said, it started out as a display.
Right you will need some info.
Weight (!) at the moment it weighs in at 2500g (5 1/2 lb in old money) To this you should add a lick of paint and a splattering of poly to keep it looking nice, and around 300g alu plate that has yet to get stuck on the bottom.
So; we now know that its a brick.
Total lenght is 1004cm and is 46cm across the hips.
Now for the real tricky bit: The hatch/motor room.... The opening in the top is a miserly 12,5 cm.
I would prefer not to chuck bits out of the top! (thus rodgering my loverly mahgany planking).

So lets have a few suggestions on what I can use to shove the thing through the water.
Drives? Rudders? Suggestions are welcome on this area too. Turn finns? will I be needing those to.

My little project has now become a nautical "Pimp my ride".   O0
Title: Re: Another Slo-Mo !
Post by: martno1fan on October 03, 2008, 02:05:28 PM
Are you thinking of electric motors or nitro gas etc?,you will need a turn fin on the right not left these things are meant to turn clockwise,never seen one with two fins but it might have been done.you could try one similar to mine and scale it down if needed?.any standard size strut and rudder for surface drive will do the job but what size diam shaft will depend on your powerplant.The one i showed you has a full mod zen 260 in it but a stock one would go well.You will probably go leccy there im not sure but something with about 3 hp equivelant ish should do.Def brushless id say and lipo batterys maybe to save weight,expensive compaired to gas though :-X.

Dam now i have to measure it lol,engine rails need to be 5" apart as for the exact size ill measure it when i get chance.the big problem is fitting the pipe in there ,because your deck is on you might struggle to get things in there maybe?.
Mart
Title: Re: Another Slo-Mo !
Post by: Hagar on October 03, 2008, 08:46:38 PM
Or I could make a custom pipe and take it out the side of the motor bay......
(read get someone to make me one {-) )
I have a weed whacker siting in the shed, that needs a new coil. Might just se if that will fit....
As far as electric motors go they are ok, but its just the 15 hours of charging for ten minuets of fun. This is whats got me thinking of petrol.
Having seen the price of a good nitro motor, a Zen is looking quite cheap!
Title: Re: Another Slo-Mo !
Post by: martno1fan on October 03, 2008, 09:29:27 PM
Forget the weedy motor too heavy and not enough power to get one of these going,your best bet is a zen if you can sort engine rails out in the hull?.Heres a pic of that slo mo with the zen fitted.

Post by: Hagar on October 06, 2008, 08:02:41 PM
Got terminally depressed trying to figure out the motor cover/cockpit.
Turned the boat upside down and have started to play with a little sheet of alu, in 0.5mm to dress the bottom contact surfaces.
Now I just got to find a heap of card board to make patterns with!!!
Title: Re: Another Slo-Mo !
Post by: martno1fan on October 07, 2008, 08:46:27 AM
Whats the reason for the alluminium? if your going to use the boat to run i wouldnt bother to be honest.For the cockpit cant you use blue foam and then glass over it and make a glass one?.
Mart
Title: Re: Another Slo-Mo !
Post by: Hagar on October 07, 2008, 07:20:48 PM
The main reason for the alu, is that the build started as a stand model. So being as I had it I used it. To be honest, it is probably going to sped most of its life sitting on a shelf in the livingroom, so I guess It wont hurt if it looks sort of like the real one.
Got the bottom of the sponsens done today, and it is now sitting until tommorow so the epoxy it 110% cured. Next is the bow plates, followed by the rear side panels, the sides of the sponsens, then the bottom its self.
I might just chicken out with the sides of the sponsens and plank them. I looks like a right pig of a shape to do.
I'll put a photo on come friday.

About the motor covers. I've come much to the same conclusion about doing it in GRP of some sort. Should be fun, never tried that before, but then I've never built a boat before either, so who knows?
Title: Re: Another Slo-Mo !
Post by: Hagar on October 12, 2008, 08:43:27 PM
Well, got the bottoms af the sponsens covered, Not looking to shabby...Photos later, cant get on photobucket at the moment (forgotten the naffin pass wordagain!!!).

Did the lower part of the bow to. Still looking at the sides and thinking how the heck am I going to do that, its just one big long compound curve!!!
Whilst thinking about that I got hold of a poly isulation board and started to mock up a motor cover. Again photos later, just got to get my brain to work and find where I hid th password!

Look forward to seeing the pics mate,by the way i am just starting a plug to make a mould for a hydro based on the rockett i have,Joe at zippkits gave me his blessing to do it so i cant wait to get started.Once i get the plug done and moulded ill start a  thread on it and show the finnished boat running as i have all the hardware and motor here ready for it apart from a  few odds and ends and a motor mount that is lol.

Title: Re: Another Slo-Mo !
Post by: Hagar on October 13, 2008, 06:26:52 PM
Sound good Mart.
Just the one photo for now, showing the Alu on the bottom of the sponsens and prow (?).
(http://img.photobucket.com/albums/v462/IanM2760/Boats/11102008095.jpg)

Dont worry about the clutter on the prow plate, the epoxy was still a bit soft, so Had to figure a way to hold it down.
Made a hatch for the motor bay, more thoughts on that latter...Just need to plank it ???

As my original title for this thread said, before Martin changed it this is "NOT another slo mo", I think of it as "Pimp My Slo-Mo". So its going to be a bit different than all the others. if I wanted one the same as all the others, I would of bought a kit.
One thought does strike me (and quite often). Maybe I should of started my Boat building with a kit and not scratch building!!!

Post by: martno1fan on October 13, 2008, 07:12:19 PM
Hi mate its looking good  :-)),i hope you dont take this the wrong way but if that were mine id keep it for show and build a less scale one for actuall running maybe similar to the one i built from Zippkits they go together ina  few hrs and run great.
Mart
Title: Re: Another Slo-Mo !
Post by: Hagar on October 13, 2008, 09:33:24 PM
None taken Mart. T'was the intention when I started, but you know how things go.
Looking at the cost of a 1/2 descent brushless and a couple of lipo packs to push it through the water is about the same as to good petrol engines!
I'm keeping an open mind.

If you do ever decide on a kit let me know as Joe is a very good friend of mine  ok2,when i start my new project ill keep you posted too.Your boat is going to look awesome im sure and i know what you mean about brushless motors theyre expensive.

Right then. Time for a little update:
The bottom of the sponsens are now plated, as is the lower part of the prow, compleat with sealing strip all the way up.
This is what it looks like without all the markerpen marks and hold downs:

The pretty pattern on the plate is the result of using a wire brush is a 'dremmel'. This will be getting done more finely in the near future.
The plate for the bottom of the main hull is now cut. Even having done it in two parts, ('cause I botched the cutting on the whole part :-X)
You will see that there are hundreds of holes in it if you look close enough.

An other angle, where you can see my next problem, erm, I mean challenge. The sloping sides at the rear of the hull. Made the template, just need to gut the plate. And they have to go on before the bottom. Good thing it aint stuck down yet init!
(http://img.photobucket.com/albums/v462/IanM2760/Boats/19102008100.jpg)
Now this bit is a problem. The sides of the sponsens where the hullbottom becomes the sides. I have now binned soooo many cardboard paterns I'm running out of card. A question: Should I wimp out and plank it, or stick with it and do it in plate alu?
(http://img.photobucket.com/albums/v462/IanM2760/Boats/19102008101.jpg)

Now about those hole all over the place on the hull plates. Bit of help here please, Anyone know where I can get hold of either alu (or same colour pins with heads)? Got loads in brass, but they look a bit off, sittin in an alu panel. So I what some in either alu, or steel. need only be real short, max 10mm. otherwise I'll have to cut them all down!!!

Now for this bit:
(http://img.photobucket.com/albums/v462/IanM2760/Boats/19102008099.jpg)
Would there have been some form of cowling around this point or would it just have been filed in with som form of sealer?

Thats it for now.

Right then. Time for a little up date.
The disaster of a motor cover, went in the bin. the only part to survive was the rather nice nose which was cut off and kept for version 4; version 1 was a wood frame with alu covering and looked like do do! Version 2 was carved from foam. As far as a motor cover it was sea-rap! I thought it looked like the space shuttle and I wont say what the misses said it looked like  :-X
Version 3 was a nose in foam, the rest in wood and plank. Didn't look to bad, sort of. No it looked odd. That died when I tried to cut a hole in it for the exhaust...
So the final version is now like this: Foam nose, covered in GRP, the flair for the cockpit planked formers, with GRP and the bit in the middle, the actual motor cover, cut from aluminium sheet and nailed on with brass pins. It is now sitting with the first coat of paint. When its dry, I'll do a picture or two for you all (both of you) to have a giggle over.

Made the side panels for the rear of the hull. They are hiding under a yard of masking tape while the epoxy sets up. Again when they are exposed I will take a few snaps.
Having eaten the last of the corn flakes, I now have some more card to make patterns from. So I have just made the patterns for the sides of the front of the hull. Oh and the dashboard.
That just needs a few holes in where the instrument would be.

I have a question: Should I detail the top decking; you know, inset hundreds of bits of brass to simulate screws?

I'm off to read up on fiberglassing a hull.

For the dash, I have cut a bit of aluminium sheet, this will get marked up and drilled where the meters should be. Bit of black card or plastic behind and fill the holes with epoxy...
did print out some dials, but at the size they had, the text was just a white blur, so I'm thinking og just marking a whit line for a needle and leaving it at that.

Thanks for the PM.

Maybe if It was a paddle mo, or a Smit-Mo-Shun, there would be a few more comments.

Right then. The sage continues. Been playing silly so-and-so's with the epoxy, and got those aluminium sheet bits stuck down. Well most of them.
Heres the bottom one. And yes it is "nailed down"!

And the rear side sheets:
(http://img.photobucket.com/albums/v462/IanM2760/Boats/slo-mo29.jpg)
Now I know what I can use those Big black things for!
(http://img.photobucket.com/albums/v462/IanM2760/Boats/slo-mo28.jpg)

Now before I go to all the bother of doing the final paint and finish on the tail fin and cock pit, What do you think, do they look OK?
I hope the cock-pit/motor covers are good enough, 'cause I ain't doing them again.

Just to let you all know (both of you) that things are still happening, just rather slowly at the moment.
Have had a few problems with my back, and a boil that had to be removed from my shoulder blade.

The wood is in the process of getting varnished. Three coats thus far, all getting wetsanded flat between coats.

Any idea as to why I keep getting 'dimples' in my varnish. I wipe down with spirit and dry it off before I paint and when it dries... Dimples!

Its Hemples and its new! It gives a great finish, no brush marks, and is good and hard when its cured.

Post by: w3bby on December 11, 2008, 12:15:06 PM
Decided on a motor yet?
Which of the many Hempel varnishes are you using?
As regards the dimples, don't wipe off with spirit just wash and dry. The spirit can leave traces on the surface.
If the varnish really is nice and hard then flat it with fine wet and dry and then polish it up.
I hope that we will get to see the finished model on the water in Malmö sometime next year :-))

Hi Ian the other Ian has a a good point dont wipe with white spirit,i allways just rub down between coats then brush off any dust outside then a quick wipe with a clean cloth then give it the next coat.

The varnish is Hemples Favourite, which was recomended to me by the guy in the local chandlers. So if its good enough for a real boat.... Good enough for me. I hope.

As far as motors go? No Idea. Its going to need a bigish one to trow it over the water. I stated it as a stand model, took a swing towards a working model, and back to a stand when I saw what a motor for it will cost. It will probably end up an electric as there are more places to run those than gas boats. Time (and money) will tell. What are motor prices like your way W3bby?

I'll give the spirit a miss this time round and see if that helps!
