   rectangular inserts

   Rectangular inserts would be problematic - too easy for the square edge to catch material, miter gauge, etc. with only slight errors in elevation adjustment.

   Making inserts is easy, using the original metal insert as a pattern attached to the (rough-cut) dupe with double-sided tape and a pattern bit in your router.
