Encouraged by that, I wondered what other jigs might be built using
only the blade kerf width as a measurement. I finally decided that if
one kerf width (as in the lap joint jig) was good, two might also be
interesting. First thought was a box joint jig, so I did a bit more
doodling and came up with this method

This drawing should be reasonably self-explanitory, but I'm already
planning to turn it into a web page with a bit of text to provide a
bit of explanation with each drawing.


I am really looking forward to the dumb ass explanation of how to make
these and how to use them. *I know it SHOULD be self explanatory ...

Ditto that. *'Splain, Mo!

I think Morris is playing around with "kerf width" jigs.
Parts A(x) are used solely as kerf width "standards" to set the
distance of the pin registration hole of the jig.

I could be misunderestimating the jig, but it seems like it would
produce rather small pins for a box joint. Seeing as how I can throw
together a 1/2" or 3/4" box jig in a few minutes using a dado blade, a
couple of scrap oak parts, and the mitre gauge, this seems to
primarily be an exercise in "doing it my way." Or I could be
absolutely, positively wrong and he has found Nirvana! ;-)
