The 29:1 ratio is the SS mount planer and the 18.48:1 is the Pro planer.
That sounds right to me as well.

There may be more motor model designators than these as Shopsmith sourced the motor(s) from multiple vendors. I am still searching for Brushes, Brush Holders and Caps that are in different vintages of DC Motors that we might could use to repair motors that simply have worn brushes.
I am not holding my breath, but someone, somewhere with a background in these types of motors may have the exact answer we need and clue us in. The labels are Shopsmith labels put on the motors likey by the vendors opposed to their own model numbers and OEM Manufacturer Name. If we knew those, we would know what parts to seek.
No one including Shopsmith would have had a complete motor series manufactured just for them due to the expense. Reduction gear variances were offered by many motor vendors in the day and Shopsmith could have selected an option there.
Here is another site that has brush holders etc. If someone near them in Whittier, Ca. cares to pick this up and take it forward by carrying in a sample or two. http://store.eurtonelectric.com/brushholders.aspx
Didn't realize this was there until today! Shopsmith V03537AD80 Armature Rewind $125.00 http://eurtonelectric.com/catalog/armat ... ure_rewind
If they can rewind the armature, then these motors are serviceable. I would bet they can match the brushes, brush holders, and caps too.
This could be a game changer....
