A dovetail joint is strong and attractive. Its strength comes from both
the mechanical design and the large glue surfaces available. The attractiveness
of the joint depends upon the skill of construction and the design and
spacing of tails and pins. The Leigh D4R Pro allows a wide choice of spacing
and adjusts for snug-fitting joints.
It creates 8° through dovetails in stock between 1/8" and 1-1/4"
thick, as well as half-blind and sliding dovetails in material up to 1-1/2"
thick; maximum joint width is 24". It cuts through and half-blind dovetails
with fully variable sizing and spacing of tails, pins and half-pins. The
jig will also cut finger joints. A spacer rod sets the fingers equidistant
for machining 3/8" or 3/4" joints and 9/32" or 1/2" deep half-blind joints
in a single pass. The eccentric guide bushing (supplied) simplifies fitting
joints by letting you quickly and precisely change the distance between
the cutter and finger assembly.
Constructed from extruded aluminum, the redesigned jig body now has fixed
integral stops to ensure joint alignment, and non-marring textured clamping
surfaces. Quick-acting cams secure the work for precise machining. Built-in
scales provide rapid and accurate fine adjustment for stock thickness
and through-dovetail fit. The finger assembly is removable and flips to
change from through to half-blind mode; this reversing action automatically
positions the scale correctly.
Comes with everything needed to get under way: 1/2" x 8° and 1/2"
x 14° dovetail cutters and a 5/16" x 1" straight cutter (all 8mm shanks),
a 1/2" to 8mm collet reducer, an eccentric guide bushing*, a 160-page
manual, and a 44-minute DVD. Router with a 1/2" collet required.
*Fits baseplates with a 1-3/16" counterbore and a 1-3/8" through bore.
