Thanks Al. Now send me some more of your students. ;-) Sorry I missed you when you brought your students over for Manufacturing Day, would have much rather been there than in Detroit for training.
Check with Cass Tech in Detroit. They should have one or two students able to do it for you.
My Grandfather taught at Cass after he was discharged from flight school as an instructor at the end of WWI. He came from several generations of foundrymen, and taught foundry, math, drafting, & patternmaking at the original campus long ago where the iron foundry was up on the 5th floor...
