An interesting commission - Maultier panzerwerfer 42

This section is for builds that are not strictly Tamiya or Heng Long. For instance, replacing the electronics from a WSN or Matorro, or even a scratch-build.

If you know anyone who has the book "Panzers in Saumar No. 2" there are several pages of a restored one they have, including a four-view drawing and several internal and external detail photos.

So with the Centurion finished, I managed some work on the Maultier

The suspension is progressing and I managed to make it a reasonable size to fit
Image

Managed to make some hub inner and outer pieces so the wheel will fit onto the WPL front axle
Image
Image
Image
that's the wheel front, here's the back
Image
Image
Shazam.....just like that (to quote Tommy Cooper)

and an idler wheel

Busy busy busy :D :D

The Gremlins strike!!! :O :O

Just when I thought everything was going so well and I was making great progress, then I get a quick message from Mike in Hawaii to say 'erm I think your front axle may be too wide' and on checking it was very much too wide.

Anyhoo I thought well the front axle isn't driven so I'll just make a new front axle and got started, and them I realised that if the front axle was too wide, what about the back axle.

DOOM. The back axle was about 30mm too wide.

At this pount I was tempted to go and kick something, and then had a McGiver moment. I had just discarded the front axle casing and shaft, which was about 20mm narrower. To cut a long story short I transferred the hex parts from the rear drive shaft to the front drive shaft and found I could use the front axle housing for the rear axle, what a relief! :crazy: :crazy: :/

Here's the pic of the modified front axle and the start of the modified rear axle. It's a bodge in the best engineering traditions but it should work. The result is that the tracks will hopefully be no more than 8mm too wide each side which should look ok.

I can't even go and have a celebratory malt whisky as we are having a no-alcohol January, but boy if ever there was a time when I could use one it's now!

Onwards and upwards (tomorrow)

So I designed and printed the brake drums and they fit nicely - this is with the axle inserted
Image
Image
Image
Then fitted them to the axle
Image
Image
Despite using the narrower axle there was still a 10mm overlap each side, hmmmm, after careful consideration I trimmed 4mm off the end of the hex shaft and tried again
Image

Much better, the overlap is now down to 6mm each side which I think probably won't be noticed. I've ordered some metal pieces to make the axle sturdy enough to carry the torque caused by the tracks, together with a metal prop shaft, so if I can get this lot together, it should be sturdy enough to do the trick and stand up to being run around the yard!

Progress on mounting the axle, I designed the mounting bracket and by some major miracle the first design and print actually worked! !!! 8O :crazy:

Still a lot to do but this is a major step forward. I've done the idler mount so hopefully that should also work. There should be a smilie for fingers crossed!

Alwyn, that is really beautiful work! Herman is going to be very proud of it, I'm sure. Thank you for sharing your progress with such a unique project.

Now we are really motoring!
Working out where the motor fits

and a suspension is born

Next comes the mountings for the motor and the suspension units

I've just received the metal bits for the axles and I'm mightily impressed, especially with all the bearings supplied. I'm going to be rebuilding both front and rear axle and steering assembly

Herman this is going to be a pretty mean base for your build. :D :D

When assemblnig the metal axle kits, just pay close attention to the front dogbones. They take a little playing about to stop them binding on steering. Sometimes they require longer dogbones inserted to replace what they come with. But i have several of these conversion kits now and have upgraded all my WPL/HL trucks with them. Probably have £250+ in metal axle kits lyaing about in various models! whooops!


Can i please ask a question. Where do those front tyres come from? They look great

Thanks for the input and advice Will, much appreciated. Fortunately we won't be using the dogbones as the front axle is unpowered. The wheels and tyres are from sasgrunt and I believe they are surplus off an Asiatam Maultier build.

Started on the rear axle rebuild, this is real Swiss watch territory! 8O :crazy:

Image
eventually after a lot of fiddling around (these fingers really don't work as well as they used to - damn aging it takes all the fun out of things!)
Image

Now the problem with all this suspension stuff is that there isn't really space under the chassis for the motor, so it will have to go above the chassis - no problem because there's plenty of space in the upper hull.

EXCEPT that the universal joint on the chassis will really be straining, so I am busy redesigning and printing the axle mount to angle the prop shaft towards the motor and print a motor housing that's angled. I think with this jigsaw I've now got some corner and edge pieces and a bit of the sky :D :D :crazy:

You are doing a brilliant job on this Alwyn, I would have leapt off a tall building long ago. :D

Thanks everyone for the kind words. The updated axle mount and brake drums are fitted and the axle now points the drive shaft in the right direction
Image
Image

Looking better, just needs the suspension bits adding
Image

Off to print and assemble all the bits
