now i'm seeing your proposed tube vise. that would be plenty beefy and would hold up well over time. i will definitely need to weld that post on the motor housing out of steel, and welding is not yet in my repertoire. i have a few friends though :] i'm fairly certain i would put all the wiring and CLIPCORD CONTACTS :] on the motor housing, to avoid having to mess with the wiring when switching from liner to shader. i like your idea, it gives me some options i never thought of...
