Step By Step

IMake sure the boards are true and the ends are square. To mark the base line of the pins, set the marking gauge to the thickness of the board for the tails.

2 Work out the details of the size and spacing of the pins on paper. Then clamp the board in a vise with the "OUT" face toward you and transfer the marks.

3 Set the sliding bevel to the angle you want (I use 1:5). Hold pencil on mark, slide arm up to point of pencil, and mark the angle on the end of the board.

4 The pins are the "triangles" pointing toward you. Mark the vertical lines down to the base line, and then mark the waste sections with an UX".

5 To cut pi7is, use a fine-tooth dovetail saw. Place one tooth up against the pencil line. Saw should be angled so cut is made on face and end on the first strokes.

6 Saw about two-thirds of the ivaydown the face and across the end, skimming along the pencil line. Then level out the saiv to cut on the back side.

Flip board over (so "IN" side is up). Once again position backing fence and chop straight down on base line. Then undercut to remove the rest of the waste.

7 Clamp a backing fence along the base line. Hold chisel vertically and top straight down on base line. Make sure backing fence doesn't move.

8 Hold chisel (bevel up) about '/i« down from edge. A gentle tap should clean out waste. Then tap straight down on base line and remove second layer of waste.

9 After removing about '/*" of waste, tilt chisel handle slightly toivard you to undercut the shoulder. Board has "OUT" side up so waste can be chipped out easily.

Flip board over (so "IN" side is up). Once again position backing fence and chop straight down on base line. Then undercut to remove the rest of the waste.

11 Since the V-cut is below the base line I (and thus below the saw cuts), there will be little splinters of waste in the corners that must be cleaned out.

m^The pins must be exactly per-I JL pendicular to the base line. Check both faces with try square and straighten out any bad saw cuts with a chisel.
