One of my favourites is mrpete222 AKA Tubalcain, he's a retired teacher in the states who's done hundreds, if not 1000s, of videos on Milling, Turning and even casting aluminium parts, a definite must watch.
One of the little jobs he did made me think about doing the same thing for my little lathe, a knurled thumb screw to lock/release the measuring dial on the cross slide.
This replaces the supplied grub-screw and lets you set '0' on the dials as a deference point and then lock it in.

I also turned a small brass disc to put under the screw to protect the shaft from wear.

All in all it works pretty well but my next project meant that I don't often use the dials on the cross slide ... that's in the next post.
