Here's something I've been working on for quite some time now

The return roller brackets on both Sherman models have been simplified for production purposes so I was interested to see how easy it would be to improve their accuracy.

It starts off with two pieces of 2mm steel.
I've made up two of the most common bracket shapes. An M32, which used to be a gate guardian at the REME museum, had both types fitted, which was handy for measurements and photographs.

I've added slots and tabs in in order to better align the piece when soldering. It also helps as the sides are quite springy, so they hold the parts together.

These prototype parts have slits cut into them to make the bending easier, but as they're only 2mm steel, I hope to be able to make up a jig to be able to fold them without the slits.

I had hoped to fill the slits with silver solder but I can't get a good enough separation between the different areas, so I end up reheating the main join. These ones are simply filled with JB Weld.

Next, the parts are silver soldered together.

It's quite a while since I've done any soldering, so I made quite a mess of the first one. I gave this one more time and preparation and the result was much much better.

This is how the part looks installed on the bogie housing.
I've gone for four holes as that is how the original was mounted. I plan to fit four dummy bolt heads to the inside face and use CSK screws in the mounting holes, which can then be hidden with filler.

Finally, a quick comparison between the stock part on the left and the new part on the right.
I should probably have sprayed the stock part with primer as well, to give a better contrast to the piece, but I'm sure you get the picture.

Here's a couple of pictures showing the different types. These were installed on an M4A2 at Tankfest 2008.

I still haven't attempted the axle and pillow block but plan to attach the block from below using two 2mm cap head screws and attach the axle from above using 2mm CSK screws.

nice bit of work adrian could easily be overlooked, i like these details, adds to the build quality. regards simon manning,

Thanks Simon

When you get down to it , there are so many little tweaks that can be added.

I'm wondering about adding bearings to the rollers. Totally unnecessary as far as running is concerned but the real one had them so what the heck

your right adrian where do you stop, but detail is infectious, and when you know some part should be there its a challenge to make the best of the build, regards simon.
