Tired of the hassle of mounting wooden blocks to your lathe faceplates? Now you can make all the glue faceplates and jam chucks you want without ever having to mount blocks on your metal faceplates again! These taps are machined in lathe spindle sizes so that after you have drilled and tapped a wooded block, you simply mount the block directly onto your lathe. The tapped block can then be put to use in a special face plate, vacuum fixture or other mounting assembly. Instructions included.
