I went to school in Pa, in the late 70's also. We had to pay for the metal we used, otherwise the class was not bad. I never worked in the field, but always enjoyed working with metal tools. I still have a hammer that I made. I started another that was going to be a ball peen, but couldn't get back on the lathe, so I only got the handle done. Someday I will run across it again (still have lots of stuff packed from several moves) and finish it.
