Bought a Kerfmaker KM-1 from Bridge City Tool Works after learning
about it from the Wreck. It does everything its maker says it will do.
I was able to make the best half lap joints I ever did.

I guess this falls into the catagory of the old cliche of building a
better mouse trap.

Now if they'd only make a BIGGER one (rat trap?).

It can be used with wider stock and/or kerf if you use a piece of the
crosspiece stock along with the KM-1 - alternatively, there's a how-to
for making a quick and dirty (but equally accurate) lap joint jig at

IN addition to a wider kerf (3/4" would be nice), I'd like the
business surfaces to be larger so I could use 3/4" blocks.

Do you have one? How wide of a dado do you want to make?

Yes, but haven't used it other than to play.

3/4" would be nice. 23/32" is a popular size. ;-)

Like I said, allowing 3/4" stop blocks would make it easier to use
too.
