Cool find today!
This is a cricible/mold set up to cast lead or brass hammer heads around an inserted handle.
We bought a machine shop years ago and there were a bunch of lead dead blow mallets. We also found a box of steel handles, but could never find the mold for casting the heads. I thought maybe they sand cast them.
I was digging through the maintenance trailer at work today looking for potential parts for my coffee roaster and look what I found! This was not at all what I expected. Interesting set up. The mold is attached to the crucible, which then tilts to pour the metal into the mold. The mold clam shells to insert the hammer handle and then for removal once it is cast.
Really cool. I was just asking someone if we still have the handles and we do. I may have to try this out one of these days.
