What is the best way to cut the shoulders on a tenon cut at an angle?
Is it easiest to tilt the blade on the TS to the angle used and nibble? Is
there a better way other than cutting them by hand?

allow its fence to swing through >30 degrees of arc. That is one router
Pat's jig looks pretty good to me. I've done this on the TS and it is
a real mess.

Back to basics.
The register of the shoulders against the mortised piece is the critical
point of the joint. The rest is to keep it from racking out of register.
So make the long shoulder cuts with the most accurate means - the tablesaw
with a sled, or a miter gage with sandpaper or a hold-down. You can use
your cutoff sled with a wedge to ensure left/right concurrence.
Now to the tenon saw, where you'll cut parallel but proud of the tablesaw
cheeks to allow you to trim with a sharp chisel.
If you've got one of those zero-set saws, you might be able to cut closer,
but it's too easy to trim, and too ugly to see torn grain in the joint to
the shorter of the shoulders is where i am having trouble. Unless I tilt
the blade the tenon is ruined. The blade must be tilted in two different
directions or the tenon must be flipped end for end to make the cuts. how
do most be people cut them? By hand or with a router seem to be the best
answers so far.
The shorter is easily removed by hand sawing and trimming, as I suggested.
Amazing how stuff crops up, though. He does both ways - vertical and
horizontal - with wedges.
Incidentally, you do know that a wedge on the right, moved to the left,
guarantees the same angle, and the blade can stay the same?
