Folks, I've made a few drawers with my Leigh dovetail jig, but this
was my first attempt at a rabbited half-blind dovetail. I must say,
I'm quite pleased!
I made 3 drawers (fronts and sides, backs will be through dovetails)
in about 45 minutes, including setup. I find that halfblinds are
quite easy and fast to make with the D4, mainly because the only
adjustment that has to be right on is the depth of the cutter. Using
the #120 Leigh bit, it has a depth of 7/16" for a half blind. Using
an accurate straight edge and a knife, I marked the depth on a tail
board, clamped it into the jig, and lowered the cutter right onto the
mark. This depth affects the tightness of the dovetail.
The only other setting is how far the cut goes into front of the
drawer (the pins mode), and this depth can be sneaked up on, and once
it's set on the test piece, there's no other setup that needs to be
done. Just clamp the pieces in, and rout.
