More classes would be good. Milling maybe. Design of mechanisms... that I would really like.
My biggest obstacle is the residential staircase to my basement shop. There is only so much weight one tread can hold once you factor the machine, a dolly, and 2-3 guys huffing it down the steps. I can't for example see myself hauling a Bridgeport down those steps LOL. As much as I'd love to.
Hammer made in class.
