While I was reading this post:
https://forum.shopsmith.com/viewtopic.php?t=6305
about the "nub" on a saw arbor it got me thinking about the recent shopsmith I picked up and the odd hub it has... well more like had.

While the reference post may or may not have a purpose that we can figure out I think mine is simple a mistake in manufacture, followed by a previous owner not taking it up with the manufacture be that shopsmith or ???

Can you spot the issue?

Anyone else care to post other shopsmith oddities they could be quite interesting to see I'm sure.

The flats for the wrench are knot equal in thickness.

On one 12in alum sanding disc , the set screw is 5/32. On the other the set screw is 3/16. They appear to be identical other than the set screw size.
Don't know if the one was re-tapped due to the alum female threads getting stripped, but that doesn't appear to be the case. Maybe someone else has a Greenie 12in sanding disc with a 3/16 set screw.

Sounds like you got a sanding disc from a 10E/10ER. The sanding discs on these machines along with the drill chucks use a 3/16" allen wrench to tighten the allen screws.

The 10 e/er used 3/8" set screws instead if the 5/16" used by the Mark 5/V. I have a drill chuck(3326) that has a 3/8" setscrew with a 5/32" allen socket. My guess is that it was created during the 10ER - Greenie production boundary. Methinks they had some leftover chucks from 10ER production and had unique(today anyway) set screws made to enable using them with the Greenie which introduced the single ss toolkit 5/32" hex wrench. The 10ER used more than one size allen headed screws.
