It measured out at .350" . When I was in metal shop we used to take transmissions apart and melt down the aluminum. We also used to melt down pennies from Canada because the exchange rate was so off.Until we got caught.I didn't know it was illegal to melt pennies.We made sand castings of all sorts of stuff.I don't think they offer metal shop anymore.
Almost no schools have a metal shop. However very few schools have vocational programs contracted out by private collages for mechnics, construcion trades, autobody, hvac, eltrical, landscaping, culinary, cosmotology, and nursing.
The vocational programs are frowned upon thoe.
