Building a surface sander for your Shopsmith (or any wood lathe) is a pretty simple and straight forward project. Several people here and on the Shopsmith Forums and in the Shopsmith Owners Facebook Group have shared their versions, so I figure it’s time to share mine. I started with the basic design shared in R.J. DeCristoforo’s version of the book “Power Tool Woodworking For Everyone” (PTWWFE) but after building a segmented ring project from 3/4” lumber that required sanding, I learned that I needed to take a different approach. That’s where this video begins.

Don’t forget to leave your questions, comments, and Cheap-shots below and we’ll address them during our mid-week video.

I’m surprised that the PVC didn’t work for you. Mine was accurate enough to sand thin veneer marquetry. I had no issues with unevenness.
Nice thing is that when I upgraded to PowerPro, I could operate it from the front.
Yours seems to work fine though and the two grits of paper is a good idea.

I’m surprised that the PVC didn’t work for you. – shipwright

Yeah, I have some ‘splainin’ to do on that comment. The PVC I was using was tubing from the core of rolls of Kraft paper that was used in the Shopsmith factory shipping department. I worked in the Academy (woodworking classroom) in the retail store just off the factory, and they were tossing a huge pile of them and I thought they held promise. At best they were 1/2 the thickness of schedule 40 PVC pipe, and they performed poorly for this task. If I were to use PVC pipe I would probably try to get my hands on schedule 120, but that’s just because when it comes to this application the thicker the walls the better. In the end I’m very happy with this design, because it allows me to used inexpensive sheets of abrasives and to use multiple grits on the same drum. I do like your design, though.

Oh, and I was one of the beta testers of the PowerPro, so I know exactly what you mean. I just wish it didn’t require me to press that “Confirm” button so many times! Scott
