Routing the end of a stair tread
The wife and I are replacing stair treads, 12 to be exact. Five are open-ended. The house originally had carpet and a board was cut and routed to follow the contour of the carpet. Now we are putting oak treads down. The wife wants to extend the treads a bit past the sheetrock. Front is the usual bull nose. Cut, the end would be square. I have a half inch roundover bit that seems to fit. Need to remove the bearing for an exact fit. Since this will be end-grain, rout from front to back with a backer? I have a Kreg table. Suggestions? Would spring for a bit if needed- 1/4 shank.
