Now that the prototype castings have arrived (woohoo), it is probably time to start a thread on the Sherman Prototype.

Looking good! Any chance of a bit more CAD to see the design from different angles?

Cheers,

I’m not a machinist, but I’m a journeyman marine blacksmith and metal heat treater, now retired. Working in close collaboration with machinists and many others in the metal trades for years, has given me a great appreciation of what it takes to design and produce these kits.

Great looking casting! These 5 axis machines are superb! Can't wait to see the E8 take shape.

Some big milestones in the last week - not only do we now have the prototype castings, but we also got the prototype tyres and tracks.

Hi,

Coming along nicely- any chance of offering steel tracks and sprocket rings as an option - I think this model could handle them
Cheers

Would not make economic sense for us to do that. After mould costs, machining time, testing time and limited market we would need to sell them for a pretty penny - which would make the market even smaller and drive up the cost even more ... which would make the market even smaller .... and on and on.

I think those tracks are beautiful! Wow. Looks like the rear upper deck, floor plate and sponson bottoms are Aluminum alloy? Is this correct? Would be nice to shave a few pounds off that way.

Great pics. I always enjoy the progress reports. With one reserved, the anticipation is barely under control.
