Some manufacturing inspiration in miniature from Ben Katz at BuildIts:
My first idea was to have a system vaguely like Bridgeport mill dials. There would be a ring with scribed markings on it which could be rotated and locked down by another threaded ring. Here’s what the parts look like: A simple aluminum handwheel, with a solid stainless steel handle press fit into it. I really don’t like the type with freely rotating handles – if there’s any slop they feel cheap.
