Tenon Master Refurb

Just acquired a badly weathered tenon master with the miter bar and knob and??? missing. Yes on e-bay!
Any one got a copy of the instructions that come with a new one?
A pix of the missing stuff would be helpful(I am not sure how the miter bar is adjusted in/out)[screw through miter bar and a plate secured by the knob??]. Is there something to keep the miter bar parallel to the work surface?(miter bar in a slot in the 'plate'?)
The weathered wooden trunion should be simple enough to duplicate. The carriage bolts etc. and de-staco clamp are salvageable. The casting is only somewhat corroded on the unpainted(milled) surface.

Does your 'new' jig look like
this?

Does you "new" jig look anything like this miscellaneous part?

Looks like a project piece. You could probably buy another one on Feebay for the price Shopsmith wants for the missing parts.

Yep! Not planning on ss as a parts source(for the reason just mentioned).

Parts Dimensions??

Miter Bar (9) length = 6"?
Base Plate = 3.245" x ? Square? Stud centered both ways? 1/4" thick?
It would appear the miter bar to workpiece face is fixed???

Indeed it does!!!:)
Be it correct that the 4 corners do not touch the work table, but that the base plate rides on the table surface???(plate = 5/16", corners proud by 1/4")
It appears the long side of the base plate protrudes 1/2" out from the 'back' side.
Thank You Ed!!!

You are correct, the corners do not touch by about 1/16". When you assemble the jig the short side of the plate is towards the miter slot. The large "+" adjustment gives you about 1-3/8" of movement (plate extending out the back side by 1-1/8" to hidden by a bit more 1/4").
Not sure how many versions of this have been made. The one I have is from I think 1991 or so.

That is a 'detail]used[/B] would be appreciated. My simplistic current understanding is limited to making grooves for splines in pix frames. I have not seen any information in ptwfe re how it is used(or a sawdust session).
I do hope there is much I have missed!
Since I need to fabricate the plate etc., a better understanding of its uses would help me to determine if any slight design modification(s) would 'help'.
Again Ed; Thank You - we seem to be the only participants!;)
Oh! Oh!
Ouch!!!! I just experienced a flash of
potential understanding!!! Is it possible the plate has a slot which holds the stud captive(under cut slot like a milling machine slot/t slot) that allows the plate to slide that 1 3/8"????
Pix of that side would be most illustrative!!!!
