Coping SawTip

When coping shoe molding, the best way to keep it from jumping around too much is to hold it up against another piece of shoe. Lay the two pieces flat on a table with the small profiles facing each other. Make sure that the piece of shoe that wont be cut is sticking out about an inch or so further than the piece to be coped. Then pinch the pieces together, hold them steady and saw away!
