Arbors for model 500 versus 510

[wfitzmauirce]

I have a SS 500 with upgraded 510 tables. Will it still require saw arbor for 500 or the 510. SS sells arbors specifically for the 500 and then the 510. The 500 seems to need a shorter arrow?

It is the table that determines the 'correct' arbor. Yes a 500 table requires a shorter arbor.

Actually it is a combination of the carriage, spacer and table that changes the relative positioning of the saw blade slot.

But, you can use a 500 arbor on a 510+ table by advancing the quill to center the blade in the table slot.

Actually it works either direction. Move quill out, or move carriage(table) out.

Back to the 'automatic' blade alignment scenario again. Only a 'correct' arbor will self align to the slot.

Absolutely true.

If you want to use the upper and lower guards you HAVE TO HAVE the right arbors. If you don't want them for safety then you do for dust collection so in the end get the right parts and we will all be better off.

The change from the original (now 500) Mark V table system to the 510/505/520 plus the new Mark 7 (same as 520) needing different arbors is the lower guard for this system having a deeper throat requiring longer arbors. Any use of the lower guard for sawing or disk sanding makes these longer arbors required. Molding now needs the use of arbor 555619 Molder/Dado Arbor Assembly (not commonly found) or 505506 Molder/Dado Arbor (previously known as the 5/8" Universal Arbor) to clear the lower guard. The Molder Head cannot be attached directly to the spindle as is possible with early Mark 5 and Model 10 lower guards. Moving the quill to center the blade will not change the lower guard clearance and the need for the longer arbors. 500 owners using the Model 500 Disc Sander Dust Chute part number 555167 can still use the 12" steel sanding disk with the shorter arbor since the dust chute is a striped down 510/520 lower guard thereby giving it more clearance. This cannot be used with an aluminum sanding disk though. Depending on how you count them there have been 16 different 1/2", 5/8" & 1-1/4" Saw and Universal Arbors made for the Shopsmith tools since 1947. This does not count Shaper Spindles, Router Chucks or Sawsmith Arbors.
