My 1/10 DUKW build
« on: June 20, 2017, 09:31:43 PM »


I decided late last year I wanted to build myself a DUKW (my second boat build) and went ahead and purchased a set of 6 wheel drive axles to commit myself!  :-)
After ordering various bits and pieces from Ebay China I began the build at the beginning of January in what felt like minus temperatures, probably was as I had to resort to gluing in the house as it was too cold.  ;D
Initially I planned on putting glass fibre over the plywood, but having never done this before I chickened out and opted to use car body filler (soooo much sanding!)
So i thought I'd share with you my progress so far  :-))
All the working gear is in and I've set this up so I can interchange the drive between the wheels, prop or both etc. I've done a quick incline test and managed to climb about a 45 degree slope so its not the quickest on land but really torque-y! Shouldn't have any issues climbing out a boating pool thats for sure.
To try and keep costs down I made myself a set of 'leaf springs' (not that they have much spring in them!) I did this by purchasing a lawn mower pull spring which I cut to size and then formed a loop each end to put a bolt through.
Lesson learnt here is that spring steel is near impossible to drill through and in fact I couldn't drill through it. So to get round this i made myself a set of u-bolts with a plate to clamp the spring to the axle. Again the cost to buy these for the axles was ridiculous- 35 PER AXLE  (for 2 u-bolts and a plate to bolt to!). I did this with some threaded bar which I've covered in some fuel hose I have spare from my rc car. This way when it clamps on it wont damage the axles.
So I'm at the stage now where I need to construct the cargo bay area which will simply drop in and out and complete the drivers compartment (windows, seats, steering wheel etc)

Looks like you're progressing very well indeed - and your idea of the "leaf springs" looks like a winner too. Looking forward to seeing more on this one. :-)

Regards,

Ray.

High Tom in the search bar type in DUKW plans have a look at my model. My model is more for sailing than running on land .You will see from the pictures it is a very detailed model enjoy.

I like the effort you have gone to on the suspension and on those covers either side of the windscreen, which look very complicated to make.

Hi Ian those covers are very hard to make. On my model all the cab area was built from styrene sheet and super detailed. Inside those covers there is a fine mesh and the engine exhaust.

Thanks everyone  :-)  ive taken the axles apart now and greased them up, the springs have been given a coat of green hammerite I had around as they started to get a bit of surface rust. All the other parts are stainless steel or aluminium so all being well wont have any problems.
Similar to Stan i just used a sheet of plastic to form the covers, i found the hardest part was cutting it to the right shape! Then underneath each is a grill which you cant really see.
I attempted to start the cargo bay today but the shed was practically a sauna so that wil have to wait!

Hi Tom if you wish can send pictures of those mesh grills. Pity you were not at the paint stage just the right weather.

Hello
Just wanted to say Thank You for posting your build. I think this site is too much trouble for me, keeps giving me crazy build ideas and rekindles old build wishes pushed away in memory, dam it.

Would you be kind enough to tell us where on ebay the axles came from?
Thanks
George

Hi Tom If you wish I can scan all the warning panels that go in the cab area and send them to you. I have enclosed  a picture of the mesh found under the curved area and some shots of the cab area. Hope these will be of use to you.

Thanks Stan that would be great  :-)) I've had a good look at your build in other posts and it looks great!

Hi George  :-)  I'm glad to hear my post has got you thinking! My axles were from ebay but from a private seller in America, they are branded Yota 2 and I managed to pick up the set of 3 axles together at a fairly reasonable price. You don't necessarily have to go full 6 wheel drive though, could go 4 wheel drive or even 2. It really depends if you need the traction! But 6 wheel drive sounded more fun so I opted for that! I'm sure other branded 1/10 axles would work just as well too.


Thanks,

Tom

Few more pictures so far. You can see the separate drive for the propeller and wheels, I could of very easily ran the prop off the same drive as the wheels, but i didnt really want them going whilst it was in the water, also the ratios are different too. The easiest way I found to change drive between motors was from a set of on/off switches operated by a a servo! There's probably a smarter way of doing this haha

It is good to see the effort being made not only to make her drivable on land but also make the two drives disengage when wanted.

I can't wait to see him being put through his paces  ok2
