I was feeling a bit manic last night, so instead of going to bed after working on the painting experiments I went out to the shop and finally made the Ultimate Cutting Oil Holder. It has a magnetized base, so it can't vibrate off the carriage when the lathe is running. And there is a ring magnet in the lid, which holds the brush in place as well. I got the idea from a video (http://www.youtube.com/watch?v=q__AZjcdBUM) but I don't think I'll bother with the gold plating step. I think I ordered smaller caps than in the video, but it works. I might make a bigger one at some point -- I had to order 4x as many magnets as I really needed, so that's not a problem.
