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.

Bingo!

Ooh! I got one right for a change.

Somewhere between. I originally wanted to make lap joints larger than
the KM-1 (I have one on order) can handle, but I was impressed with the
simplicity of its principle of operation. When I watched the Bridge City
video, my reaction was "Of course! Why haven't I been doing that?".

Mine was "Why haven't I built that?"

As discussed previously, I have a wobble dado blade and I'm too cheap to
spend for a real stacked dado set - and I picked up on the "kerf width"
paradigm.

It's not exactly nirvana, but it comes close because it's quick and easy
to make, wonderfully thrifty, and awesomely accurate.

By virtue of it generating it's own references, accuracy is a given.
But no dado stack? Morris... Tsk,Tsk... ;-)
Just think of what you're missing: flat bottomed grooves with clean
edges; no finagling with that wobble width adjustment; respect from
your fellow wooddorkers who pried open their wallets and bought a
stack of carbide tipped blades and shims in a fancy box. And please
tell me it's not a Craftsman from 1962... You surely are a determined
individual. ;-)
