|Fine-Tuning Miter Cuts
of the most frustrating jobs for most woodworkers is cutting miters. No matter
how carefully I work, sometimes the joint just isn't as tight as I'd like.
Today's power miter saws make the job of cutting miters much easier. But it's
still a rare occasion when I'm completely satisfied with the fit of the joint.
There are almost always some small gaps.
miter saws come equipped with micro adjustments, I've found that the best way
to "dial-in" those critical cuts is by shimming the workpiece in the saw. This
means mitering a couple of scrap pieces and testing their
If the gap
is at the back of the miter, position the shim behind the workpiece and away
from the blade, see photo. This trims off a little from the front, tightening
up the miter near the back edge.
If the miter is open at the front,
place a shim near the blade. This will have the opposite effect of putting the
shim away from the blade.
This technique should
only take a few minutes and a couple of scrap test pieces, but you'll end up with
a perfect fit.
