brass T-34-85 from Poland, scale 1:10

[vanhasen]

Hello everybody,
It has been a long time since I am building a model of T-34 tank in 1:10 scale. I started this project a long time ago, and as first "to do" on my list was to make my own casted tracks. It took me some time, but I did it. After that "to do" list grew significantly longer, as my assumptions regarding the model were quite ambitious:

- soldered brass hull, made according to factory drawings with the original thickness of armor plates (target mass of the model around 34kg),
- casted Zamack (ZnAl) tracks,
- casted aluminum turret (in fact with help of a friend I also managed to cast real cast iron turret) - with 360 deg. rotation and correct gun elevation range
- casted brass wheels, including "spider" road wheels with rubber bands.
- all other parts originally casted also made with the same technique,
- easy to disassemble brushless powerpack with custom gearbox,
- ElMod electronics (luckily I purchased one before they downgraded their product )
- FPV with 3 cameras.
- custom Li-ion battery pack
- realistic gun recoil with smoke generator
- mechatronic features as moving periscopes, opening hatches.

Long time ago I scratchbuilt a T-34-85 in 1:16 scale. I loved it for mobility, but I always had a feeling that it is too small. 1:10 scale gives a lot of space to make it even better.
But to make it all I had to improve my tools and learn a lot, so instead of starting with model parts I had to start with upgrade of my workshop so I built centrifugal casting machine, vulcanization tool, electric furnace to melt aluminum, injection machine for rubber, press etc. etc. Learning cad was also essential. This job took me roughly 4 years ...

What I have done until now... Well - practically I am finishing the build. I am putting together the electronics, which at this point become a bit complex. I am trying to make it as easy to disassemble in the field as possible.

I have a lot of materials covering this build, so at the beginning I will show just 10 photos allowed by the forum. I will show more if you will be interested.

It's a beautiful work, I admire

Wow. Great work.

My God, that is exquisite!

That is superb. You're certainly taking scratch building to the next level.

I shake my head, pinch myself. Can I really be seeing this? What an incredible masterpiece!

I was born and raised in Milwaukee, Wisconsin, US. In the 1950s, Milwaukee was home to dozens upon dozens of machinists of German and Polish heritage, men of incredible skills. Now I see in your skill the kind of work those people accomplished a long-gone time. I am awed by what you have done!

wow, more more more please

specially the casting of the tracks is interesting...
actually, all parts are interesting

[Markocaster]

Incredible work.
More photos please

Well, tracks were for me the most important part of the model since if I had fail to make them, I wouldn't be able to complete the tank.

I did it using a centrifugal casting method, it was a mult-stage process. Everything I did by myself, literally in the garage - centrifuge (https://www.youtube.com/watch?v=tcSiT0_npj4), form curing tool, electric four able to melt aluminium.
This is a relatively easy way of making repetitive elements, but result is limited by the heat resistance of rubber molds. Zamack is probably max (around 490 degrees Celcius).
In theory it allows also to cast other metals, for example pewter, lead, lead alloys. I tried only zamack.

It is crutial to prepare heat-resistant patterns, as the rubber mold has to be cured in 200 degrees Celcius. Printed patterns probably won't work.
Don't pay attentio to my centrifuge speed/noise. Normally I used it at far lower rpms.

I've heard of others using the centrifugal casting method for T34 tracks in 1/6th scale also.
