I have never
been able to cut dovetails by hand, at least I couldn’t cut them
good enough to suit me. I decided that there has to be a way to
do it that would allow mw to succeed. I remembered reading on
Oldtools List that a magnet sunk into a jig would guide the
saw and help it to cut a straight line.
Here is what I came up
with. It is crude, but it works. I cut the pins first, then mark the
tails and cut them without a jig. I think this is going to work fine,
but if not, I will just make a similar jig for the tails.
I started by making a
piece of maple about 10” long by 1 5/8” thick by 3” wide. I cut a rabbet
1” by 3/4 into one edge. This is to allow the jig to sit on the end of a
board and be clamped in place.
Next I cut it in half, then I cut all 4 ends to a 7
Now I bored a counterbore
into the end grain of all 4 ends to accept the magnets. The magnets need
to be set into the wood just a tiny bit deeper than their thickness so
that they will attract the saw blade, but not grab it.
These magnets are about
3/16” thick and 1 1/8” diameter.
Next I rabbeted the side
opposite the original rabbet so I could glue on a skirt. The skirt is
what gets clamped to the board being cut.
