has anyone tried this? I'm casting bronze, if I were to make some pins out of bronze to hold to investment core in place, and then left them in place in the final casting, just cut them down and polished over them, would that work? only issue I see is that they could oxidise during the burn out, but maybe the reductive atmosphere would prevent the worst of that? And if the metal doesn't actually fuse together wouldn't the cast metal shrink around and lock in place the pins anyway?
