I need help or suggestions. I am casting some dive planes and will need to have the final product with a shaft hole in it. The solution I have seen others do, is cast the piece with a brass rod in it. After the resin hardens, the rod is removed. So, what do I need to do to assure the rod will be released?
(hopefully this makes sense, if not please ask me to clarify)
