I have been working for some time now on a vacuum chuck for the lathe. This will allow me to hold work to the lathe without any screws. It took some time to get a vacuum pump off of eBay, I kept being out bid at the last second, I got a nice Edwards e2m12. Then I had to figure out the fittings that attach to lab equipment. I found a kf25 to ½” pipe connector. Then it was just household plumbing. From left to right in the photo I have, the vacuum connection, a bleed valve, the intake filter, vacuum gage, and the vacuum pump. This will all fit up into the ceiling above the lathe.
