We currently have a restock of improved side bead planes in the store.  These are available in bead sizes of 1/8″, 3/16″, and 1/4″.  It should be mentioned that our sizing is a measurement of the bead itself, and that the actual profile, including the quirk, is about 1/32″ wider than the bead size.  Thus the 1/8 is 5/32″ wide, the 3/16 is 7/32″, and the 1/4 is 9/32″.  More information about the side beads can be found here.
