Y ou can imagine my sur-
hinges are misaligned.
Correctly positioning the
hinge in the first place remains
thekey. Then an accuratemortise
is cut tomatch the hinge. Thekey
word is accurate. If the mortise is
off, you've got problems.
That's where this jig comes in.
We devised an adjustablejig that
let's you set the size of the mor-
tise to match exactly the size of
the hinge.
All you need is a router and a
patfmx bit to rout perfect hinge
mortises. (A pattern bit is a
straight bit with a guide bearing
on the shank, instead of on the
end, like a flush trim bit.)

prise at the cost of the
panel saw we were look-
ing at purchasing for the shop -
over $1000. It's a nice piece of
equipment, but that's a lot of
money to spend.
Panel saws are used to cut
sheet goods (plywood, ete.) down
to manageable size. It's one of
those tools that you don't think
you need . . . until you have the
chance to use one. Then it sure
would be nice to have in the shop.
The biggest benefit is that you
can easily cut 4x8 sheets down to
size - by yourself.
The cost of this type of saw
usually puts it out of range for
most home shops. In almost
every instance like this, my first
thought is, "Okay, let's save
money by building one ourselves."
It took about five weeks to
work out the design details for
the Panel Saw. Hardware turned
out to be one of the key elements
in the design.
It wasn't that we needed spe-
cial, hard-to-find hardware. The
tricky part was coming up with
ways of using common hardware
in rather uncommon applications.
In the end it worked out great
- we got the panel saw we
wanted for the shop. And only
spent about $250 ($100 for mate-
rials and $150 on hardware).
HINGE MORTI5ES. While the
panel saw is an impressive piece
of equipment, it may be too large
for some workshops. On a smaller
scale is the hinge mortise jig in
this issue.
Setting hinges is one of the fi-
nal critical parts of cabinetmak-
ing. It can break a project if the

Sometimes the
idea for an article comes in a
rather round-about way. Re-
cently, I brought a couple of old
hand saws into the shop to
sharpen. (Oneof them appears on
the back cover.)
The sound of filing the saw
teeth brought severalpeopleinto
the shop.
Their reaction seemed to be
the same -wouldn't it be easier
and faster to take the saw to a
commercial saw sharpening shop?
Easier perhaps, but not faster.
To prove the point, I gave a
quick demonstration on how to
sharpen a handsaw.
All you need is a few simple
tools and a little patience. The
trick is to let the saw be your
guide. And to let the triangular
saw file do all the work.
Over the next few days our
workshop was fdl of people
bringing their dull saws back to
lie. The result of all this activity
is the saw sharpening article on

formed by cutting a notch in one
side. This notch is the openingfor
the pattern bit.
BACK GUIDE. After the notch
is cut, the next step is to cut a
back guule (B) from 3/4"-thick
hardwood, see Fig. 1.
This backguide provides a sur-
face for the bearing of the pattern
bit to ride against as it cuts the
back of the mortise. And it helps
align the end guides (which are
installed later).

LOWER STOP. After gluing the
back guide in place, I added a
lower stop (CI, refer to Fig. 3.
Once this stop is cut to size, it's
attached to the base withapair of
machine screws and T-nuts. The
screws are mounted in slots to
allow you to position the back

see Fig. 2.
To make the slots, first drill
start and stop holes. Then clean
out the waste on the router table,
see Figs. 2 and 2a.
