Step By Step

IMake sure board for tails is true and ends are square. Then set marking gauge to thickness of board for pins. Mark base lines on both faces and both edges.

2 To mark cut lines for the tails, use the board for the pins as a template. Place pins on base line and mark from the inside corner with a sharp pencil or scribe.

3 Notice the small gap between the pin a nd the pencil line (on the44good" side of the cut). The saw cut should remove this gap to allow a little room for clearance.

m ^^ After corners of tails are cleaned up I w the joint can be tapped together. Use a backing board for even pressure. As joint goes together, check boards for splitting.

4 Hold pencil on corner of board and g Angle board in vise so lines are al- £L Clamp backing fence along base line move try square up to it. Mark lines & most perpendicular. Place tooth of and chop straight down. Then chip out straight across on the end grain. Then saw right up against the pencil line (so kerf waste. Note that waste should be slightly mark the waste sections with an UXis on the waste side) and make cut. wider than the chisel for easy removal.

7 Flip board over and align backing fence to chip out remaining waste between tails. Only straight down cuts are made on half-pins (don't undercut).

8 To clean out waste for half-pins, chop straight down on shoulder line (marked in Fig. 1). Then pare out a small V-notch so saw rests against this shoulder.

9 Place saw against shoulder of V-notch and saw off waste for half pin. This saw cut will be somewhat rough so clean up the shoidder with a sharp chisel.

nlf base lines were marked less than the thickness of second board, the pins and tails will be recessed. Use a plane to shave board down to the end grain.

1 If the pins and tails stick up above I a the surface of the boards, use a file to level them off. Heavy paper protects the face of the boards from scratch marks.
