Just checking to see if there has been any movement on casting our own platform. with the shape of our platform being relatively easy to mold/cast - is there any reason we cannot use the plaster method? Also, are there silicon rubbers that stand up to the heat needed to cast aluminum 1200 -1500 degrees? I have been doing a little studying on this and thinking I might give it a go this summer if our current plan will be pushed out far.
