BTW I am not sure why he made a cut out, it seems to serve no purpose.

The cut out reduces the amount of contact surface area, which has the potential to reduce error. Errors in the few thou of an inch are enough to influence fit.

About 8~9 years ago Bridge City Tools came out with a fine little jig

I bought that expensive little jig and have had great success when using
it.

Seems there is a shop made version now and probably the absolute
simplest that I have seen.

Take a look!

It's simply a "stick" and "a screw".

I will say that it may not work as well for large stock but maybe it will!
