Shattered my 10ER Drive Pulley
Posted: Sun Aug 23, 2020 4:59 pm
New member, first post, 22 year owner of my grandfather’s 1952 Shopsmith Model: 10ER.
I have performed a fair amount of maintenance to this machine over the years without incident, but that all changed today.
Needing to replace a noisy drive bearing, I attempted to remove the pulley from the drive shaft after removing the pulley set screw, but it would not budge on the shaft. So I removed the drive assembly from the headstock, and soaked the shaft/pulley interface with penetrating oil. I then attempted to drift the shaft from the pulley with a wooden dowel, but as the end of the shaft started to pass through the end of the pulley, it became more difficult until the aluminum failed and shattered like glass.
I thought I was covered, as I had obtained another 10ER years ago, and kept most of the parts as “backup”, for situations like this. However, I learned today that my backup pulley is for a keyed 5/8 shaft.
I know this is a long shot, but does anyone know of an online resource where folks trade 10er parts? Like I said, I have many 10er parts that others may be willing to trade me a 13/16” drive pulley for.
I know of MKC Tools, and plan to purchase one of his beautifully machined pulleys if I cannot locate an original via trade, or reasonably priced.
Thank you for any advice you can offer.

No luck in the short term finding a replacement pulley, so I contacted Skip Campbell with MKC Tools for one of his custom replacements. I just received the replacement today and was astonished by the quality. Not too many products today are produced with this level of attention to detail. Many thanks go out to Mr. Campbell for bailing me out, and making it so that I can continue to use this wonderful old machine.
