years back I built this boat in 1/24th with a set of plans and basic tools, have posted the work so far on the thread for this class of boat, decided to start a build thread of its own.. today the double planked 4ft hull was cut free of the building board..

Wow, that woodwork looks impressive, I'll follow your build and hope to pick up some tips along the way. :-)
Regards,
Ray.

You have made a lovely job of the hull. :-))

Hi,
One of my favourite boats.
Hull looks great.

Hi I hope you don't mind have posted a shot of my Whaleback.
Same scale as your build.

That planking looks very neat. What timber and glue are you using?
Charlie
-
thin 1/8th" ply framing, basswood 1/32nd" for double planking,hard balsa blocking, superglue and titebond III wood glue,, with the help of homemade half round scraper the stringers were reduced, blocking fared and other uneeded interior wood removed, after sanding a entire 2oz was removed but that means the first 2oz of epoxy are free weight.. plans are to make her as the 180 out of Gorleston in late war fit (well armed and well worn)

hull interior has been cleaned up and epoxy coated.. starting on exterior hull and deck..
-
deck with cabin and hatch openings framed, 1/32nd plywood sub-deck fitted and with the help of a few clamps, weights and other objects glued into place,, outer hull sanded and giving a penetrating coat of resin, after another round of sanding it will be glass and resin time..

hull sanded, mixed some epoxy filler paste and filled seems, divots and gaps.. after curing used a 5inch orbital sander to bring everything down to a point where the hull can be glassed, some final hand sanding is still needed.. (working big is fun) started on the deck planks until my spray can of superglue kicker emptied..

planking done, penetrating coat of epoxy applied.. time to glass the hull and start main cabin construction..

Lovely piece of work :-)) . It will almost be a shame to paint it.

work started on the plug to make a mold for the cabin.. getting close to starting to sheet this section.

I would imagine you would need to keep the weight down on a high-speed craft like this. What is the target maximum all-up weight for the finished boat that you need to achieve? I'm loving all that diagonal planking, superb :-)
-
Way back I spent several days dremeling out hull-cabin and hollowing out fittings on my 1/24th so it would ride correctly and get up on plane.. calculations for the new boat says 10-10.5 total.. with this concern the cabin will be a thin fiberglass balsa sandwich (after I get the mold made) the use of 3D printed parts for many of the fittings and crew should help keep the weight in check(20mm, Vickers machine guns, vent cowls,searchlight) brushless motors and new battery tech will help greatly..
-

sheeted the regions that curve in one plane with thin ply, the tougher curves were covered with narrow planks.. sanding, filling and more sanding needed to get the plug ready..

Motor is a Turnigy 3648 inrunner motor 1450kva.
I run on the centre shaft only, flank props are freewheeling.
Boat runs on a three cell lipo which gives more than enough power.
Runs just as well on a two cell lipo.

Motor mount made from plywood faced with 1/8 inch alum as heat sink have also curved alum tube around front of motor which is watercooled.

Hi fellows
I am using one of these 3648-1450kv motors on a 60Amp car ESC with a 40mm 2 blade prop.
Using a 5800mah 3S Lipo the speed of your boat will not be a problem.
I have run this motor with a 3 blade 37mm prop, but ,it only used more amps and did not go any faster.
-
Hi made a mistake in my post it should say Outrunner motor not Inrunner.
Prop I use is 36mm three blade brass.
Graham
-
Using a 2S the revs are about 10000, 3S the revs are about 16000 and 4S 21000.
This turns these motor from mild to beastly!!!
Yes I tested it on 4S, but, the solid ply 34" Sea Commander was not built for speedboat speeds!!!
I have removed the motor and installed 3548/4 1100kv which is still over speed.
-
(http://imagizer.imageshack.us/v2/320x240q90/921/nsvKrj.jpg) (https://imageshack.com/i/plnsvKrjj)
my current plan is 3 24-28mm 900-1200kv out-runners, 3 battery packs (to be decided) 3 ESC.. I'm in the planning stages of converting a transmitter to 3 slides with center detent for the trottles.. this was in the works already for my 1/96th scale USS Minneapolis (C-13) also the triple screw..

have to admit its fun working in a large scale for a bit..
-
(http://imagizer.imageshack.us/v2/640x480q90/924/Fy7W1l.jpg) (https://imageshack.com/i/poFy7W1lj) filled,sanded and primed.. ready for more sanding ,filling and priming (but, I got to use my 5inch disc sander)
-
The 28mm motors only run 3blade 30mm props, but 35mm motors will run 37mm props(eg 3639-750, 3648-850, 3639-1100).
Depends on what prop sizes you are planning for the boat.
This requires three ESCs and maybe a throttle/rudder mixer for the outer motors.
-
the scale props are prop shop v1212 just a tad under 30mm and not a racing pitch, was looking at something in this range for motors
http://www.hobbyking.com/hobbyking/store/__18968__Turnigy_D2836_9_950KV_Brushless_Outrunner_Motor.html looking to get scale speed and trying to stay away from water cooling.. planning on the vent cowls to be functional and mounting a exhaust fan below the open engine room hatch(possible ducts to pull air through motors) the ESC's come with fans,,
-
I love the look of your PT and the Dreadnought hulls! It always seems a shame to cover up such lovely timber colours with paint.

wheelhouse section of the plug completed and joined to the aft section, after more filling and sanding details that can be part of the mold will be added.. then the fiberglass mold can be laid up (this plug almost weighs more than the hull!!)
-
back to work after some vacation time, while doing some reading (RN ASR book) discovered that the D-Day markings for boats was a 5 point white star in a blue circle field.. I know somewhere I have seen this on a whaleback but can't seem to find the photo.. looking for a link or help as this would fit in the time frame I'm working on..
-
started getting the parts made that will be included in the mold plug..

started working on a master for the turrets, plans, drawings and photos were clashing.. the museum at Flixton came to the rescue and provided measurement and detailed photos (with measuring items)I produced a rough set of 1/16th scale drawings that should work.. now to turn a new corrected form..

BOULTON PAUL DEFIANT Mk.I
hi there there were two versions of the gun turrets - one came from the above which was for the single gun and then when they modified it for the twin gun I believe the canopy came from either a Lancaster design or some heavy bomber. Christian will be the best one cos he is the one who advised me.

I was wondering how you were going to create the Canopies, as they seemed the most tricky out of all the components. I will watch with interest these latest developments :-))
Charlie

current "plan" 1/16th square brass soldered inner-frame, vacuum formed clear sections, outer frames and center sections photo-etched brass,(hoping with the first 2 layers together a pattern can be made for the outer frames ),.. yes this will be fiddley.. but its a fun break from 1/96th work!!!
-
turret frame construction, decided to use 1/16th square aluminum stock (had to cut 1/16th plate to make it) filed half lap joints and JB weld (a filled epoxy) clear turret domes were vacuumed formed before grooving the plugs for the frame forming, now to start on the second one..

Very impressive build.

You could simplify things a bit as I can recall reading some years back that the glazing was often removed from the turrets as they had a tendency to steam up in use.
Jim
-
Thats a big wow from me, nice work
-
thanks for the comments, the build method for the frames seems to worked as I was able to get a second bird cage together that matches the first one.. learned a few things on number one , so the second's build went a little faster and smoother.. now to get back on the main cabin plug work ..

turned some balsa stock for making the carley float, turned the start of a basswood plug for the DF loop.. the cabin plug was prepped, glassed up, hopefully there will be a good mold under that mess (the base layers were much neater)

I echo Colin's WOW! Because those turrets are gorgeous just on their own. I know of at least one modeller who gave up on making one of these because of the turret glazing so kudos to you for 'finkin' it all out. I imagine that being a larger scale, they are easier to develop.
I have only just seen this topic so will take much more note of your progress on this beauty.
-
thanks everyone, the 1/16th scale makes some things easier, but is unforgiving on other details..the Carley float floor has been built, float and rings have been ribbon wrapped to simulate canvas..

sacrificed some clickster pencils to the cause as stock for navigation lights "glass" turning while wearing the opti-visor, took a bit to find the correct speed and use of lube/coolant (soapy water) may try to refine this a bit but have to find some more stock!!

had to make some 20mm parts after messing up detailing the 3D printed parts.. unimat with the opti-visor work.. may be I need to work with some of my 1/96th scale stuff before the 1/16th drives me further crazy.. I thought it would be the other way around..

Wow, I've learnt some fantastic information on the gun turrets as for years we've tried to work out how to build a realistic looking versions for our Walton 65ft ASRL and we are going to use yours as a basis. :-))
-
thanks, I tried to see if I took a photo during the glue-up stage, but must have been not sure if it would work so it wasn't documented.. lots of half-lap filed pieces of bent aluminum all held in place by about twenty small alligator clips and twist of small wire..(slow curing filled epoxy helped by giving time to make adjustments) on the second one the main arches were set first and let cure making fitting in all the other ribs the next day much easier.. finding a small 1/16th wide flat file and a 16th dremel burr sped the making of the lap joints..needle files to clean up everything after..
-
Hi Nick, re Walton on Thames boat. I have the magazine article with bulkhead cross sections showing a flared hull, quite different to the MM plans. Also some detail regarding rudder tiller operation, that's from memory.
I mentioned this in another thread, perhaps you have this already. I think I got the information from the RAF museum at Hendon many years ago, I think I saw a Mr. Lion there.
regards Roy
-
Hi Roy
Yes I remember that magazine, I think I've got one of the newer reprints.
The hull, and to be honest a lot of the fittings, isn't right but with a bit of research looking at the pictures of the original boat it can be built into a lovely boat. My Dad met a chap at Warwick in 2008 during the boat show who had built a fleet of 1/48 scale ASRL from original plans and he kindly sent a copy of the Walton plans to him showing the differences between the MM plans and the proper drawings.

work on this project is restarting after the summer off, found some great color footage of boats in action and have made some more great contacts.. the boat footage is in the last third.. red inside the vent cowls, an added stern plate, better views of the added searchlight..

not a dead project,, just have way to many things on the bench, a new milling machine for a live steam project.. but I had to do the glass work for a friends destroyer hull, seeing the whalebacks cabin mold was ready and the resin mess was happening.. the deck cabin was molded with balsa wood shaped and bent to between layers of glass clothe,, still needs filling and sanding,, but it seems to be very light and strong ..
