I'd be interested in some tracks gears etc for the Grant I'm going to build
and to re-fit the track system on the Brumm to make it more desert
friendly....

I know that molds have a finite lifetime. Typically
how many castings can I expect to get from a silicone mold ?
When properly maintained, a rubber mold can be used for hundreds of
castings. We've had no problem making tread parts for multiple tanks
with a single 8 tread mold.
Regarding set time: It doesn't take long to pour resin into 6-8 molds.
Once you've learned the process (spray, measure, dye, mix, pour, pop)
things go pretty smoothly.
I'm leaning toward molding and casting myself, but I like Franks offer
of "prototype parts for molds". At least I wouldn't need to make my own
molds and I could still play with a Thing-O-Matic.
Now we're talking. John White (KT builder) is ready to crank out dozens
of CAD designs for tank parts. Together, we can form the un-holy
trinity of mold making :-)
