I have a whole bunch of scrap 6061 and quite a few pieces have stainless bolts broke off in them. I am thinking just tossing them in a crucible and the stainless will sink to the bottom allowing me to pour a part and then drain off the extra aluminum and dump the stainless junk at the bottom. Any problem doing this? I’d like to clean and cast in one go to reduce how much propane I burn. Getting ready to pour the same pump housing I did before without adding the silicon to see how it compares.
