This is someone else's idea. I'm unsure who now, but thank you. After my original chip shield busted at it's hinge, I was going to make a new one when I spotted this idea. I had a spare magnetic indicator holder that I didn't really like anyway, so this idea made use of it and was much easier to make than something like my original chip shield. It's also infinitely versatile. It can be stationary or, mounted on the carriage, it can follow the tool. Incidentally, that little 3-jaw chuck had a TIR of less than 2 thou. Hooray for me!
