Finally my disk sander is completed and ready to use. That’s a great tool. All I needed was scraps, a 1/4 HP electric motor (1725 rpm), a pulley, an electrical box, a switch and an electric cord (plus skills and imagination, of course!).

Respecting the direction of the rotation (here counter-clockwise) is important at a disk sander, reason why I used a permanent marker to indicate where the disk spins upwards, part that must not be used.

Make your own, you certainly won’t regret. More photos and all details are available on my blog.

I was thinking about doing something similar, but a table / disk to use based on my 1236 lathe as a power source…

Good job on the sander Serge, as all your other projects. Have you thought about cutting a hole under the table for a shop vac (or dust collection) hook up? Thanks for posting.

@dbhost: I seldomly use a dedicated 12” MDF sanding disk screwed on a spare faceplate on my faithfull 1236 Rockwell lathe. This disk is for fine sanding since I can slow down the speed easily. But my new disk sander is for regular, daily and heavy sandings.

@jjstroud: $300 is the reason why I built my own. I’ll get pictures from the one I built few years ago for a friend of mine and post them here for LJs to look at and…. be inspired.

@radu: Yes, shown on the details on my blog.

Great job. I read your blog on this very detailed. I plan on using the blog as a reference when I overhaul a disk sander I jsut inherited from my father in law. Thanks.

sweet. I like the variable speed, and the dust collection in the bottom. I’m sure you could hook up a hose right to that bottom and it would suck all that dust

Thank you all for your comments. And don’t forget to show yours!

@Mads: I’ve been using one for more than 20 years and as you mentioned, I do love it. I dismantled my old floor model and made this benchtop model. My shop is too small for a floor model. And I’m glad I did.

@Roger: I soon found out that sanding on lower speed means easy stalling. I’ve taken the habit to dim the switch from Medium to High speed only. As shown below, I added a dust port and it does a great job. It is connected to a Craftsman 14.5 amp 20 gal Shop Vac.

Nice work Serge, simple and easy!

How well the 1/4 hp motor works?

I have one motor that looks about the same size as yours but there’s no indication of power or RPM, nothing, and someone told me it may not be powerful enough for a disc sander:

I had the idea to build it the sander with one side as disc sander and the other side as spindle or belt sander, in a rotary base so I could change the motor position for proper access, what do you guys think?

freddy – google how to check the current draw of a motor… it should be pretty easy.

a belt sander on the other hand, sounds a little harder to make – it needs to have a way to push out the spindles as well as provide tracking on one end. not saying it cant be done, just with much more difficulty than this job!
