A year or so ago I floated the idea of several tankers pitching in to have an injection mold made for track treads. I was using e-Machine shop and it looked like the tooling cost would be about $3k. I had exactly zero interest. So, I developed a "screwy you guys, I'm going home" attitude and decided to try something on my own J

They could pop a few thousand out at a time. heh. Has anyone thought of injection molded hulls or tanks as a possible lower cost or less time consuming option to get more people into tanking? I know the plastics will hold up to the abuse.

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".

Together, we can form the un-holy trinity of mold making :-) Frank P. -- You are currently subscribed to the "R/C Tank Combat" group.
