For the pulleys the position, as you point out, is important as it shows in the picture.
I believe you are referring to the 10E for sale in Texas for the following comment that is part of the Shopsmith 10E Shaper Fence? thread.
I remember I had commented on that elsewhere. Also the original poster for this thread wasn't showing a Jig Saw.Picture 13 in the ad is a home made guard/dust collector for the sanding disk,

I get mixed up sometimes too. Example - Even though I had restored over a dozen Model 10's I was doing the table alignment of a newly restored Model 10 and couldn't figure why I could not get the table to align front to back. It finally came to me that I had attached the rear table bearing P/N 103-4 upside down. Something that doesn't make a difference on a Mark 5 but certainly does on a Model 10.
So many Shopsmiths running through my head and so little brain power left to even keep them straight.
