It
can be tricky trying to make the end grain coping cuts on the rails of a frame
and panel door without this handy router table jig. During assembly the end of
the backing board is aligned with the bearing on your coping cutter. Then, just
position the end of your rail flush with the end of the backer board for a perfect
tear-out-free coping cut. Add the T-Track Plus with a user made stop to make cutting
the opposite end of the first piece and any subsequent pieces of equal length
is a simple matter of clamp and cut. The Build-It Clamp is required for this type
of cut so don't forget to pick one up from your local Incra dealer.Add
a Miter Slider and (2) T-Slot Panel Connectors to a small Build-It Panel and place
in the miter slot at your router table. Adjust the Miter Slider to fit your slot.
Cut a piece from another Build-It Panel to fill the gap between the existing assembly
and your router collet. You'll want this piece to be about 1" narrower than
the distance between the T-Slot Panel Connector and the 1/2" shank of the
cutter. Cut 3/4" material for the fence to 4" x 18", then cut the
(2) 5/16" wide slots as shown. (The slotted holes will permit support for
angled work but you can simply drill (2) 5/16" holes spaced 8-1/2" apart
if you are only interested in a 90 degree fence position.) Attach the fence with
Build-It Knobs and 1/4-20 x 1-1/2" hex bolts with washers then add the 18"
T-Track Plus. The T-Track should be offset from the business end of the fence
by 2" to provide safe cutter clearance. For most coping work, the fence should
be adjusted square to the edge of the panels with the end just touching the cutter's
bearing guide.
