Shown is a 2.5” diameter faceplate and set of small faceplate clamps for my 3” swing Unimat SL 1000 lathe. The faceplate is made from 12L14 steel machined on the face with evenly spaced 0.1” witness marks. The clamping holes are evenly spaced and tap for 10-32 screws.
I also made three faceplate clamps from C360 brass. These have an additional 10-32 round C360 brass nut on the backside for the clamping screw to use on the faceplate that came with the Unimat and shown in the last photo. The round nuts are not needed for the 2.5" faceplate. Each clamp has separate 4-40 screw for leveling the clamp.
The idea for the brass faceplate clamps came from one of the tool articles published at Adventures in Watchmaking** - Home and I previously posted another version of the clamps at Homemade Faceplate Clamps.
