Also, if I recall correctly, a mold master needs to be made a little oversized to account for shrinkage during the casting process.

I tried to mill down the MDC zamac frame to narrow frame

hello Bob, and all other interested parties:
personally, i think the thing to do for the MDC tank car is make a
frame for it.
i have a spin casting machine, i can get a mold made.
i am not a machinist and therefore can't make a master pattern myself.
in my opinion, the MDC frame is about 2x thicker (top to bottom)
than it needs to be.
so, now where to get a master pattern.....
