If you use Aloris type tool holders, it always seems like there is never enough of them to leave "tooled" up. Magnetic bases seems to attract more chips than I have physically made for some reason, so I like to mount my indicators on the tool post. I didn't like the idea of sacrificing one holder just for an indicator mount, so I came up with a simple mount made from scrap 1" square tubing. The dovetail cut is with a bandsaw, the rest was simple.
