Transfer punches can be used in conjuction with a magnetic v-block and a disk sander to provide a useful way of trimming glued-up pen blanks in preparation for turning on the lathe.
Select a transfer punch of a suitable size to go inside the pen tube, and with the v-block held firmly at right-angles to the sanding dick by means of the powerful on/off electro magnet, place the transfer punch in the V of the block to allow the blank to be slid forward on the punch and offered up to the rotating sanding disk.
This transfer punch set comprises 28 pieces, from 3/32" - 17/32" (2.4-13.4mm). Each punch is 125mm long, and the set comes complete with a storage base. For ease of reference, each hole in the base is marked with the size of the punch.
