I am in need of some 1/4 scale exhaust stacks, and it seems no one produces what I need. So I am considering casting my own from resin. I think I can carve a plug ok, but I am looking for a website with instructions for making molds and actually casting the parts. I think what I need to do is make a mold from some sort of silicone, but not sure. Let me know if you have done this, or where to learn how.
Thanks
