Chiseling mortise bottoms

Remove the waste between the mortise sides with a mallet and chisel. Mount the stile to your work bench as shown, clamping it firmly in place. Select a chisel the same width as the mortise, or as close as possible without being wider. To clean out the waste, place the chisel Vs inch in from the bottom of the mortise and tap it with a mallet so it sinks about Viinch. Set the chisel back toward the end of the board by about lA and tap towards the first cut to remove a small notch of waste. Continue in this manner until you reach about half-way. Turn the board over and remove the rest of the waste. Finally pare straight down at the shoulder line (above).
