Richard,
I already have a better hand wheel... see photos. I have not used the compound since installing RELS, but still have it and the compound hand wheel for future possibilities.
The trouble with a pin is that it makes it more problematic to remove the handcrank. (I know because that's how I installed my X-axis lead screw extension. Removing it is a MAJOR PITA.) There are other options... key, set screw, double set screws, solid pin that is held in by threads at its end, etc. I would have to double-check, but I
think I changed the lead screw extension to a long set screw last time I had it apart. But I still have the ridiculous arrangement with the hand wheel mounting. Who thought it would be a good idea to rely on a friction fit with an axial screw?!?!
