Corner Post Tail Cuts
From this point forward all we are doing is using standard
half blind dovetail techniques to join the four rectangles of
wood. Here is a quick review.
Use the remaining short pieces of your material for the
tails. To cut the tail boards, we’ll begin with the dovetail
shaped rabbets. Move the INCRA Jig to a scoring pass
position and tighten the
clamping knob. Make the
scoring pass across both ends
of both pieces. Increase the
full rabbet width to 7/32” with
three subsequent passes,
moving the fence back 1/16”
for each cut, Fig. 46 and
Detail 46A.

Now, clamp the two tail boards to your Right Angle
Fixture as shown in Fig. 47 and make the tail series of
cuts. The first cut for any tail board will always remove
the edge of the stock. To keep this first cut clean and
splinter-free, it’s a good idea to return to a 1/32” scoring
pass, then sneak up to the first visible mark on the
template in one or two passes. Make the tail series of
cuts across the width of your material. After completing
the cuts, flip the boards end-for-end and repeat the cuts.
Position stop as close as
possible to the outfeed
side of the bit
Corner Post Pin Cuts
Slide the stop positioner just up to the outside diameter of
the cutter and clamp in place, Fig. 48. This stop setup will
always produce a socket that is a little short, so cut one
end of one piece at this time, then adjust the stop position
as necessary before making the final cuts on both ends of
both pieces. See the tip on page 4 for more information on adjusting the stop position. Remember, if you used the “B”
cuts when cutting the tails, you’ll use the “A” cuts for the
pins and visa versa, Fig. 49. After completing the pin cuts,
assemble both pin boards to one of the tails, then add the
other tail board and drive the tails home. Try this
spectacular joint on your next jewelry box project.

At this point, you can cut the
pins just like you would on any
other half blind dovetail (see
