I make quite a lot of doorways with cope-and-stick joints. You need to
have the fence aligned with the bearing on the bit for all of
the operations, and when you’re routing the ends of the rails
the setup will get even trickier. For that operation, with each the
miter gauge and fence guiding the workpiece, the fence not solely
should be lined up with the bearing but in addition needs to be parallel
to the miter slot. To get the fence arrange exactly I’ve
all the time needed to make a sequence of tedious changes on every finish.
Someday, after getting the fence aligned, I had a brainstorm. I
sized a hardwood runner to suit the miter slot, utilized a bead
of glue to the highest, dropped a skinny piece of plywood onto it
with its edge in opposition to the fence, and popped a couple of pins down
into the strip with my nail gun. I had simply created an prompt
alignment information, which works for the entire cope-and stick
operations, plus different molding bits too. Now I simply put the jig
in place and push the fence in opposition to it whereas locking it down.
It really works for any router bits with the identical measurement bearing. I
don’t insert the bit till after the router fence is aligned,
but when your fence gained’t allow you to try this, simply make a cutout in
the jig so it would match across the bit.
