When you had that it resembled a saw blade and the rip fence could be mounted to the right or the left.... and yes the rip fence was tilted differently depending on which side the rip fence was on. The disk also did not care which side faced which side so that was another option.
I think, or at least I think I do, the 510 still had the option. The 520 is the first one without the ability to off set the fence. I made a "L" shaped fence that I could use as an off-set fence because I sell like that feature.
So there was a reason that it was made to go either way.

Not I!
I am only aware of the Mark VII 10" disk with flat/conical sides. I guess it could have been mounted 'reversed', but I do not think it was intended back then. With reversing capability it would have been unnecessary.
I do not know when the 'dual' off setting screws were introduced on the '500'. I assume the bandsaw fence was after that.
I believe the 510 always had both screws. <<<< nope! only one!
Interesting, the Mark VII has both screws. The book by Christoforo(Modern Power Tool Woodworking - PTWFE ala Mark VII) only shows the flat 12" disc(but does mention the 10" flat/tapered one). It does refer to sanding with reverse rotation(front feed, sanding at the rear) which would require reverse offset, so two screws. FWIW, the book says 1 1/2 degree taper(half the current conical disk).

I still have my 510 fence and it appears to have only one screw. I no longer use the fence and it was disassembled to scavenge some parts from and my memory of there being two screws appears to be incorrect. Or at least the vintage I have seems to have only the one screw??
The dual sided sanding disk I have came from Craftsman and I would have to say the early 1970's. I had it on my rockwell table saw which I had before I got my shopsmith. The angle was listed as 2 degrees but then shopsmith says 4 degrees and that seems to be more like 3 degrees...........
On the 510 I could never get the bridging to work out and before I spent to many hours on it I decided to upgrade it to a 520, just like my other machine. I've also changed to a table with the smooth center section which I like better, so not much of the old 510 left on that machine.
For the two 500 vintage machines I have the same rip fences I also have the newer version with the t-track top that I got as an upgrade to my original machine (before I upgrade it to a 520). I believe the one with the t-track is the version that is also the modified (shorter) bandsaw version so it was a later introduction but I don't recall the year. I don't think that t-track version was anything but an option, ie I don't think any 500 shipped with it as standard. Anyone know for sure?

I also was incorrect. All of my 510 fences are single screwed.
It remains a mystery why the later 500 had two screws. Maybe a common mold for the bandsaw fence?
I don't think SS added a screw so the craftsman disc could be used.

Do you have the manual to use as a guide? There is a process involved and getting the alignment right is critical for safety as well as good woodworking.
I don't recall if you have a copy of the bible Power Tool Woodworking for Everyone (PTWFE). If not that is something you really should have in addition to the manual.
I spent a lot of hours using my 1976 machine (that I got new) as a 500 before upgrading it to the current top of the line powerpro/dual tilt/520. I still like the 500 for a lot of smaller jobs and in fact have two of them.

Yes Ed, I do have Power Tool Woodworking for Everyone (PTWFE) -- written before my SS was made
Hi. I stumbled across this forum just a few days ago. I purchased my Model 500 new in 1986, after seeing a demonstration at a mall--$999 plus $100 for the freight. It was allot of money for me at the time, but it has proved to be money well spent.
Anyway, about the set-screws. My PTWE book that came with my Shopsmith shows on page 268 that the set screws are used for temporarily skewing the fence when using the 12" sanding disk to sand boards to exact width, or remove saw marks. It shows using the right screw to skew the fence to the right, so one can feed the board in from the back of the saw.
If you were to mount the sanding disk on the auxilliary spindle (page 265), then the fence will be one the left of the sanding disk, and would need to be skewed to the left. Thus, the need for the left, or second set screw.

That would be the 1984 edition.
Interesting conjecture re the second(left) screw.

I like this idea on the reason for the "other" set screw. That makes perfect sense and I have even done it that way..... just not recently.
Since there is a very limited number of ways of collecting dust on that side of the machine I no longer think of going that way, well that and having more then one shopsmith so if I want to set up two sanding disks I can just go to two machines, both with dust collection. This could also be a reason the 510 did away with the second set screw (or not). Much better way to collect dust exists in the table or to the outside with the lower housing.
I got my shopsmith in 1976, I paided $745 if I remember right and it came with a 3 day class and a couple of extras, perhaps even free shipping..... to long ago to remember clearly anymore.

I was just now reading through this thread and was about to make this very point. The original patent for the Mark V fence had only a single set screw, and if I remember correctly I've seen a few of these in the field. Yes, the set screws are used for temporary misalignment, not for alignment. If you leave them in the 500 fence they can vibrate out, which can cause misalignment or even the loss of the setscrews. When I was a SS Academy Instructor we used to suggest that people remove the setscrew(s) and put them into the miter gauge protractor, where they can be used to lock-in a miter stop block and you'll also always know where they are when you need them. The single setscrew on the 510 is much longer and because it engages more threads and has a dab of Loc-Tite on it, they tent to stay put. Scott
