I am trying to make a piece about 4 x 6 x 1" thick with a pocket near one end. I will need to make a slot for an insert sheet. Think of a picture frame with one end where the photo is inserted. I am looking for a 1/16" [maybe 1 - 1 1/2" in diameter] slot cutter which I can run around the inner circumference of the pocket to create a slot for the photo. My problem is that most slot cutters have some sort of fastener which extends beyond the cutter and will not allow the slot cutter to operate at the base of the pocket with zero clearance. Anyone heard of a slot cutter like this?
