Btw, could anyone tell me if the motor is about the same era? Do the oil cups require a special oil or will 3in1 work?here is a pic.

Only "downer" that I am aware of is it tends to wear aluminum pulleys/sheaves more than a plain rubber belt.

One last question. This one also had a cast iron extension table. We’re these switched to aluminum at a later date?

AIUI yes. They are rare however.

JPG is correct. I don't think anyone is sure when they were sold. They are very rare. I only know of three and yours makes 4. I have one, I think Russ has one and someone else on the forum has one.

Stex10er,

Your Model 10E being serial number ER10611 was likely made in late 1948 or possibly early 1949 and came from the Eastern Plant. The ER in the serial number designates it as coming from the Eastern Plant and E was also used first for Model 10's coming from the Eastern Plant. Early serial numbers with no letter prefix or the prefix R came from the Western Plant. Later the letter prefixes were dropped no matter which plant the tool came from. The serial number letter prefixes of E, ER or R should not be confused with the Model numbers using 10E or 10ER. They are used for different reasons although similar.

The motor on your Model 10E is not one I have seen before and would take some research for the company and motor model to tell when it was made. Magna Engineering Corporation sold the Shopsmith Model 10E and 10ER with or without a motor, a buyer's preference if they already had a motor that would fit. The Motor supplied with the Model 10E and 10ER was made by A. O. Smith and was commonly a 1/2 HP motor. An optional 3/4 HP A. O. Smith motor was available. Most of the more than 20 Model 10's I have restored came with an A. O. Smith motor. Do remember to check and add oil regularly to your motor since it does not have sealed bearings.

The Cast Iron Extension Table is rare as John said and I do have one too. It was not original with your Model 10E. The Model 10E first came with a wooden Extension Table and was later changed to the Aluminum Extension Table in 1949. I believe that was after your Model 10E was made. It looks like from the picture the bracket is the longer one. I now believe these rare Cast Iron Extension Table were produced nearer the end of the production years of the Model 10ER. I now have a Cast Iron Mark 5 Extension Table which is the only one I have seen. It may have been a preproduction test extension table for the Mark 5 when they were in design and testing while the Model 10ER was still in production. The Cast Iron ones for the Model 10ER may have been a test to try them as a possible change. Ultimately the Mark 5 came out with an Aluminum Extension Table similar to the Model 10ER although a different mounting.

Below is a link to a Forum Thread you may enjoy titled Shopsmith Model 10's What When and Where I started. It has a lot of information on the Model 10E and 10ER.

I would use the 3-in-one motor oil, not the 3-in-one multi-purpose oil.

Thanks for the advice rpd

To avoid possible misunderstanding the 3 in 1 "motor" oil is referring to electric motors, not the automotive type "motor" oil.

Another descriptor is machine oil #10. Turbine oil Sewing machine oil Zoom spout . . .

Note the 3 in 1 "motor" oil is #20.

For sheaves, #10 is recommended which I believe multipurpose 3 in 1 oil is.
