I have often wondered about why they did one thing and why they didn't do another or do something differently. Then when you get to looking at the situation it usually becomes apparent (one of those DUH!! moments
).
There are a lot of little things that could maybe have been improved here or there "IF" they were designing a single purpose machine... but they were not... A two purpose machine creates a whole new set of problems and compromises. A third mode compounds the process. By the time you get to five having everything still working together is pretty amazing.
Then factor in that a lot of us work quite differently, have major height differences etc. and shop space limitations.
Based on those factors those old original designers can still be pretty proud of themselves.
As I work on my SS's I still am impressed with them. Of course that does not stop me from wanting to customize my stuff and I can do that but starting from scratch took some real doing.

Saw Kerf with respect to Insert Centerline

This has been an interesting an frustrating adventure but the trip is now over.
The results: All anomolies were the result of Main Table Alignment. I had repositioned the table is such a manner that the blade, while parallel to miter tracks, was no longer centered in the cutout for the table insert. (The procedure does not address this.)
Furthermore, I had repositioned the table in such a way that the drill line had also been changed. (The procedure does not address this.)
The details of all of this is contained in this thread and it has all been summarized here in this sketch of the table top. I hope this is helpful to some of you.

I'm off to make sawdust again.
Well, later.
The notes that have been truncated should read as follows:
The blade depicted is .062" (1/16").
The Table insert cutout measures 3.035"
Inserts should be cut to 3" for clearance.
Main Table alignment must include parallelism of the miter track to the blade
as well as position of the table with respect to center line of the arbor (13").
