After I became interested in the Shopsmith Model 10’s I didn’t realize for some time that at first the Model 10E came with the ½” Arbor (P/N 102-35X) as opposed to the 5/8” Arbor (P/N 126-1X) that came standard later. Both were available but as an optional accessory for the one that didn’t come standard with the Shopsmith. The 10E came with an 8” Combination Circular Saw P/N 110-1. Later the 10ER came with an 8” Combination Tooth Saw Blade, 5/8” hole P/N 110-4. That is how they were listed in the manuals. I guess the early 8” saw blades (P/N 110-1) had a smaller ½” arbor hole. Maybe someone can confirm this. All the old 8” Shopsmith/Magna Saw Blades I have that came with Model 10’s I’ve owned have the 5/8” arbor hole. Out of the first 5 restorations I did 4 were Model 10ER’s and the 10E had upgrades including the Metal Extension Table and a lot of accessories with it. That’s the main reason I didn’t realize this for some time.
While we are talking about the Model 10E arbors, the one shown in the Fig. 1 picture on the first, type written, Owner’s Manual shows a different ½” Saw Arbor. Mine did not come with that arbor so if anyone sees one, I would like some pictures. It may have been a kind of mock-up from other arbors and parts from that time period. 1/2" and 5/8" Arbors were a common item with both 1/2" or 5/8" bores. It's the reason non-Shopsmith Arbors get mixed in with Shopsmith Tools. It is marked as #12 in the fig. 1 picture below.

The Fig. 1 Model 10 and some accessories are different than the production model
Headstock (Changed on Production Models)
1 No Logo/Serial Number Plate
2 Set Screw hole on front for drive sleeve and not one for the Belt Cover bolt on top
3 Different Belt Cover with no visible mounting
4 Three lobed Quill Advance Knobs
5 Different Way Tube Lock lever
Carriage and Table System (Changed on Production Models)
6 Different Way Tube Lock lever
7 Different Table Tilt Lock Handle
8 Doesn’t appear to be a Carriage Positioning Stud with Nut (103-29 & 29N) or it may be hidden by the Way Tube. It may not have come on the first ones but the threaded hole was in the Carriage.
Accessories (Changed on Production Models except as noted)
9 Miter Gauge has 45-degree angle cut on right side to clear blade when cutting 45-degree bevel cuts
10 Drill Chuck Arbor not beveled like part number 102-47
11 Sanding Disk has only four ribs not six
12 Saw Blade Arbor not the same as 1/2” Arbor P/N 102-35X
13 Different Lathe Tool Rest, has removable shaft for attaching to the Arm, later it was single Casting. Original Production models have this Tool Rest (S/N 1077)
14 It is hard to tell from the picture but the Base Plate may be different from the production model. The Base Plate in Fig. 1 appears to only have curved angle braces on the inside of the verticals that the Arm attaches to. The Production version of the Base Plate both large and small have a cross brace at the bottom between the two verticals. (Changed on Production Models)
5 & 6 the Way Tube Lock Levers may actually be the same as the production models but due to the quality of the Fig. 1 picture it is hard to tell for sure.
It is hard to tell from the fig. 1 picture above but it may be a Knob instead of a wing nut holding the extension table bracket to the tailstock.
The picture below is a recreation of Fig. 1 and it shows how the first Model 10E's came from the factory with one slight exception.
We will discuss that exception later but in the mean time see if you can guess what it is.
