Hi Well I have just started to build The Tito Neri tug
Second I will (honestly) try to post some photos of the said build as it progresses if I ever get to work out how to do it! post pictures that is..... ;D
I'm still not sure how much I will fit into the hull but I have some thoughts on where to mount various controllers etc to enable loads of scope in what can be fitted so I'll try to keep some info going (work permitting)
-
Yes, i want to know the best way to post pics, I've been using imageshack, but to many ads on it now. Do you HAVE to use a hosting service or is it possible to post onto the site?

Read "Resize Picture " on menu on Mayhem home page.
Happy new year.

Catengineman lots of pics. please. Tito Neri is on my "Next But One" build list.
At the risk of offending Martin and other Mayhemers, I refer you to another Forum (in USA) where a professional, helpfull, skillfull builder is giving a commentary on his Tito Neri build www.rcgroups.com. Scroll down to "Boats" then find "Scale Boats" and look for "Tito Neri comes to life". The author is Umi R.....something, he is very helpful and tolerant of basic questions.
www.themodeldock.co.uk offer a CD with a lot of pics of a Tito Neri build for £10. To be honest I do not think it is good value. True there are 60 or more still pics of various stages of build which are clear and good quality but they are not organised in any sequence and there is absolutely no commentary or notes. You would do better asking Umi for pics and tips.
Keep us abreast of the build, please.

With the intake of a few scotch's this may go wrong but here go's anyway.
I purchased the Tito Neri basic kit from Westbourne Models and took it to the ship I work on (seemed a good place to go as I had to start my 14 day purgatory) :'( :'(
The first picture is the kit in its raw state then as they progress there are several stages.
I will say that with only a little bit of alteration the frame work was able to be assembled without glues.
The last picture is once the frame work has been fixed which strengthened up the hull ready for transport back to Lowestoft.
-
Looks good. From my reading of other build logs most builders seem to find the frames are a good fit and slot together well.
What is the Instruction Manual like?
I presume the two holes in the deck timbers are for the towing post. Do you intend to strengthen this area? Does the towing post get supported inside the hull? In one build I saw that a metal/epoxy armature was inserted in the towing post, rather than the wood which I believe is supplied. Strengthening the towing post and any attachment points seems imperative to me when you realise what towing force this tug is able to exert. I would be inclined to extend to the bottom of the hull and fix there very securely.

Martin has already found RCgroups, ive seen him posting there, and the umi you speak of, is Umi Ryuzuki and SHE is a most skilled modeller :) and full of knowledge and advice

I'm not over impressed by the instructions it's just picture plans though they are to scale.
The gog eye or towing post is made of plastic but I will be forming mine from steel, and yes it protrudes through the two holes in the deck and fixes to the hull.
I will be making mine from steel as I know it will be towing some large items when it's completed ;D
I am hoping to construct a working tow winch for this build but at the moment I have to recover from Christmas ;D

speak of the devil! hi Martin!!
-
Hi Catengineman & Roger in France.
The two holes are not for a towing post
The towing is done from the double winch
drums or the tow hook situated behind the two holes.
Regards
john.
-
Yes, after I posed my question and sent the post I knew somebody would pick me up on that!
Of course the tow is attached to the hook but these two holes take a guide arch which must feel a great deal of strain (particularly when the tow is not exactly aft). In the kit I know there are two U shape mouldings in plastic and the Instructions require two lengths of wood to be inserted in the legs of the inverted U before the plastic shells are joined. This leaves the bottom of the U (its top when inverted and in place) hollow. This seems to me and others a tad unreliable.
However, it leaves the question....How much strength can you apply to attachment points and tow rope guides? I guess it all depends on your boat's layout. However, if you are anything like me you always do a belt and braces job (never use a 2" nail where a 6" nail will do!!!! I was taught some of my "skills" by a blacksmith from the Plymouth Dockyard). I have this awful image in my mind of someone having a tow attached, applying "All ahead" and then watching the superstructure slide off the stern!

Well done Roger, got the bottle working then!!
Richard ;)
-
Hi Richard, yes the bottle is working thanks to Ken C. and Martin (I gave them the thanks they so richly deserve under "General Chit Chat" - Animated images.)
I was amazed to find that the animated avatar is retrospective and now runs on my old messages.
What can that boy Martin not do? (Did somebody cruelly say, "Finish a Puffer?". Shame on who ever it was!.
Roger in France.
-
Yes . The Animation is backdated.
I found this out when I looked back at one of my letters which said it wasn't working , and there it was, working in all it's glory ;D
It's almost as satisfying as finding, when you come back to the boat the next day, that the glue has finally set, .
Cheers...Ken

Hi guy's
Well yet another HARD two week work have been completed and the Tito Neri has spent some more time in the "dry dock" aboard the ship, :) :)
With the latest bad weather I have managed to get a few bits done on this build.
I managed to fit my choice of motors 'Graupner BB700's and with the help from Westbourne Models found that the drive coupling needed to be double length to accommodate the original motor mounting points.
I have fitted the hardly splicer's at 90 deg to each other.
The fore deck is fixed down and a coat of filler used to finally seal the edges and any blemish's in the bullworks.
I gave the hull a 'mist coat' of paint to show up any filling Mark before final sanding and spraying a primer coat.
As you may see the accommodation has had some more work and I have constructed bridge desk etc for aesthetics.
I built a compartment inside the stern WTD and fitted a switch ready to control the recever power supply I managed to make a pair of hinge's and a dog for the door out of brass rod
Ill stop with this post now or Ill be in trouble .
-
I'd say it looks good but hell i've seen it for the last 2 weeks so what do i know !! ;D
-
Must learn to clean up on the desk oops (work bench) before taking any more pictures ;D ;D

Hi,
Have you thought yet how you are going to operate all the various servos?... I have just paid for but not yet received this kit from Westbournes. I didn't buy all the radio control gear yet. I went for the same motors as you but at some time later in the year I'm going to have to start thinking about a new set of RC.
I'm watching with fascination!!

Hi Alan,
Yes the radio gear I intend to use will be NAVY F14 with extra switch gear installed to give me at least *8* channels, though I'm getting very impatient and really want to get it into the water :(
Still all good things come to those that wait :) :)
I haven't altered the steering servo's(yet) as I want to see what it performs like, BUT then to make it true to life I should have 360 deg control and then would only require "forward only ESC's" which if I leave it as is then to get stern thrust I must install ESC's that handle both directions.
That said it looks like I will end up getting several ESC's all of which are NOT CHEAP :( :( Though I may have a couple of very old mechanical ESC's that could be fitted to try the operations of the ASD's
As for actually having the radio gear in my hands NO NOT YET (lots of kisses going to the wife and cooking and cleaning O and building a new closet in the bedroom in hope SHE will get the set I want ??? ??? :)
The kit you have ordered from Westbournes--- have you ordered the # fittings kit # as well?
I could not get it at the time of my purchase as 1 not enough dosh, 2 they didn't have any in stock at the time.
You said motors, will you be fitting the ASD's (schottles) or converting to fixed shafts and rudders?
Richard.
-
I,m like the guy from Gilbert & Sullivan..I had a little list! however!!!!
I ended up going the whole nine yards..fittings, schottle drives, the lot except radio & and ESC.
Those I'll try to sneak past SWMBO later in the year...
Haven't got it yet...hopeful for tomorrow Friday

In another thread I wondered about the control of model boats with a laptop and wifi. My son, carputer buff, is working on a system to do this.
If it comes to anything then I'll fit it into Tito meanwhile we got control of servos etc from the laptop but slow going on using a playstation control (loadsa buttons) for the various inputs. The boat end is not problem, he says!!
more later

Hi Alan,
So what comes in the fittings kit then?
This is where you tell me that there are better faileads and the winch/s, windlass and mooring bits are all in the kit just waiting to be glued in place ;D
Wifi to control tug? mmmmmmm now there's a thought. Software to sort out.... no I think for now the standard route will have to do. :) :)

"Anchor winch,towing winch,Hydraulic crane,boat crane,fire monitors,railing stanchions,liferafts,signal lamps,companionways,radar,bollards,lifebelts,anchors,portholes,and other small fittings" it says on the box.
The kit is sitting in its box in the middle of the room, it has taken over.. I couldn't get the box in my FTO boot, had to go behind the seats, that does not look good for trips to the pond :( I liked the warning not to throw ones self into the water to retrieve it should there be a failure!!
I got visions of going 'bottom' over tit gettin it into the wet stuff.
I have a warm glow just now....
more later

Just thought that I would post these two pictures of the Tito build.
With the ingress of family members to my home and the memsaab wanting stuff done I have only managed to fit a few hours in on the build while at home, (still back to work on Wednesday ;D and the dry dock contines. ;) ;)
-
when I fitted deck brace 22 I found that the hull "thickness" stopped the mounting flange from going right through. did you have work around for this??
alan
-
I hope it sticks!!
-
banjo,
Hate to tell you this, but there's enough 'gas' in those weights to blow the deck off of that hull! Then again, if you could vent it in the right direction (variable), you could pull water skiers with it.

The Campbells are coming .. :D
Seriously though ....good work

Hi alan,
Firstly sorry for the delay (WORK got in the way of my true love Oh and mayheming) back onto frame part 22 "yes" I did find that the ASD units would not pass through and so I took the trusty dremmel to them and opened the holes up until the flanges went through without catching.
To tell you the truth I only found this out when I tried to turn one of the ASD units via its servo ARRRGH one servo with stripped gear drive !!!
I also have raised the hight of the ASD flanges with the aid of a thin rubber gasket as I found that the servo base fouled onto the inside of the hull which did cause some stress to be placed on the drive cog against that on the vertical shaft cog.
I'll post some more pictures later once the misses has forgiven me for spending LARGE amounts of money ;D ;D

Yeah really,like thats going to happen !! :o

I've now got the decks all fitted.
I was really pppped off about the way those schottel drives had to be opened up. Large screwdriver, pincers etc. the whole thing looks as if it was butchered, that was why I waited till the paint job was finished so that I didn't have to go at them again. I suppose if required that bronze (?) bush could be replaced by a spare from Graupner.
I had some "gloop" left over from fitting the lead shot in the keel so I used that to help strengthen the area around the drives without thickening the vital access holes. The action bits now move freely after the dremel modification.
I am going to wire up the drives and servos in tandem so I can "sea trial" it using my old two channel radio gear.
My son has been working on the "master system" I detailed in another thread using his carputer. We can control the system from a laptop (on the bench) joystick, using a playstation hand thingy. This connects to the carputer in the boat.
The laptop gives a schematic showing a realtime feedback of the nozzle positions and % power to each drive. A camera in the wheel house also feeds back a view from the boat.
Various other buttons can be used for the bowthruster, fire pumps etc.
The thing that took the time was the programming involved in getting the joystick interface but this seems to work now.
(I am hoping to also be able to fit a belt and braces conventional control system to overcome the vagaries of Mr Gates products but thats something for me to to battle over with my boy) watch this space.

Right OK first off I (YES ME) have regained some of my own life back ;D
I have payed penance and sat making new curtains for our newly decorated bedroom and have stayed away from the "Toy Tug Thingy" which is costing tooooooooooo much B####y money (her words)
Hey I managed to get out into the workshop / garage and I now have a working forward winch
This is all fine but now I have to get another set of items so I can control it from the transmitter :'(
So onto some pictures
Quite how I will gain full control over Mesabi and the tug is yet to be sorted ;D ??? ;D
The chap in the last photo IS captain Jack (just admiring his work on the painting) :D ;D :-[
-
I am goint to try and get this right?
I'm doing some thing wrong I just know I am!
I want to get the picture with the description under it but ?
Hey with a brain like mine it's not surprising I can't do the simple things.
Richard,

Hi Richard,
The easiest way is to use photobucket ....
or just attach one picture per post... :-\
I want to get the picture with the description under it but ?
Richard,
-
Thanks I seem to be OK for posting but thought that I could have put a small description between each photo, may be it's just me being lazy and not wanting to post post post, you know do it all in one go then sit back and admire all the mistakes ;D
PS: I thought I had gone loopy loop until I actually read that you had moved the site about still great job and a fantastic site with a very good member gathering (if you know what I think I mean)
Richard,

Great winch..
Source??

Hi back again,
This time the photos are of the (slightly messy) wiring for the power supply board to receiver, radar, light systems and two temporary switches controlled by old servo units.
The bow winch and anchor winch fitting, the bow winch motor and gearbox have been mounted into the anchor cable locker (OK a plastic box supported on wooden beams) Hey its my build so's I get to call it ;D
The anchor winch is only a modified servo and I made a slipping clutch to avoid snapping the chain (Failed on that one) :'( but it works very well and with a stronger chain it should be OK.
I have a pair of contacts that supply 12 volts from one of the main batteries to the PDB which gives out one 12 volt feed one 5.4 volt feed and one variable feed (this is to the radar drive to get a realistic speed)
You may see that in the bow of the tug there are some servo extention lead ends these are for the ESC's when I get them and bu having the receiver in the accommodation then I can rest assured that water should not get any where near it (lots of hope on my part there) :D
I tested the bow winch out by running the rope through the forward tow eye and made it fast to a hook in the roof of my garage, when I operated the winch the bow was lifted clean out of the stand before the winch stalled just before the full weight of the tug was taken on the rope.
Now I know the tug will not have enough 'grunt' to out pull it's winch but then again the tug cant over run the winch either.
Richard,
-
Had a day in the shed (garage) with the expensive toy as my wife would have it called, and with a new anchor chain fitted, a full 2 meters in length I sat walking it out then heaving it in until the anchor stowed in the box, and success the chain is good B&Q do sell some decent stuff after all! :P ;D
I had to settle for brass chain but hey ho I'm not a purist, just a happy chappy,
Richard,
-
Spent the day in the workshop / model construction room / garage,
After some work carried out at 'work' I set to making a carrier for the tug (a trip to the boatting lake and carrying it made up my mind)
So armed with an old cheapy sack barrow and some stout wood I fashioned a wheeled carrier that holds the stand Tito is sat on.
A dob of paint and presto no more back ache for me!
thats the launching device and now the carrying device all finished and with the 'new' power supply (don't tell spanner) I hope to be off to the lake again tomorrow
Richard,
-
Nice yellow is this the colour you used on the sack barrow ?
Jenno.
-
Oi CAPTAIN, sort the yellow box out !!!!!!
-
Hi, big sorry chaps not sure where I went wrong.
So here are some pict's of the said carrier 8)
-
Wow!,
Got to the pond again today and the weather is great---- not too much wind some brill sun and only one or two resident ducks in the way.
A few pictures of the tug underway and even though I had to let spanner take control things went very well over two and a half hours before any battery drop ;D
It was not until I looked at the pictures that I saw the anchor out of the box, but I had anchored in the middle of the pond earlier so I must see the optician and have my eyes checked again. ;D ;D
-
Nice build you have there, wheres that lake it looks really nice to sail on ???.
Jay
-
Home town 50 meters away is the sea! and a great beach
though with the waves out there as high as they were I would not want to chance the tug in surviving very long :'(
I checked on the net and asked around, about my local club and water and the little lake I have the tug in is where the local club is supposed to use but I've not had any replies or seen any other boats ( very peacefull and quite lonely apart from the squirrels, "flying vermin & seagulls" duck and the occasional finch)
The nearest club other than the 'local' is in Norwich (NMBC) around 46 miles away :'(
I'll take the tug to work and sail her (pc = IT) at the Warsash training lake when I can work permitting that is.

(I mounted the servo horns on the underside of the steering gear for clearance on the HS-645MG servos... Make sure the gear is clear of the servo...)
-
Umi,
Thanks for that info. A closer inspection revealed the cause of the "popping" of the servo screw to be lack of clearance as you suggested.

Is that a PC motherboard inside your Tito?!?!? :o
What job does it do and what are you downloading via the USB memory stick?? ???
Martin.
-
.....................what are you downloading via the USB memory stick?? ???
Martin.
That 'memory stick' looks like a USB WIFI adapter to me, I have a remarkably similar one attached to one of my machine round here somewhere.....
-Rob
-
Hi Martin,
Its the sort of mini motherboard used by car puter enthusiasts.
The "memory stick" is a WiFi aerial like you use indoors to network your computers.
It networks with a laptop on the bank or pondside.
There is a module plugged into the motherboard usb connection which is used to control servos etc.
Ole' computer control of a boat from a "playstation" handcontrol plugged into a laptop.
It only works when I have number one son with me! otherwise its running on a Robbe Navy setup.

Wow! Impressive. :o
OK, anyone out there got or seen a more completed boat than Alan's Tito Neri with mini PC, wifi and Playstation options?!?! ;)
