Slow and quite, so easy on the nerves.
Home made power tools are worth the effort.
The tables came out of a ShopNotes magazine.

Your situation may be different than mine so make sure of your measurements and observe all safety precautions.

Simple and functional. What more could a person ask for? Thanks for the post.

Great Idea. This made me think of an old homemade bench grinder I can convert to this setup.
Where did you get the backer plates for the sandpaper?

Great idea, two different grits? I would be interested in knowing more about the construction and what was used for backer plates. Do they run true?

Say, quicksilver, what did you use for shaft bearings through the plywood.

Thanks for the post.

I am curious, though. If you have 2 Shopsmith disks, do you have a Shopsmith? If you have a Shopsmith, why not just use it as a disk sander, the table is bigger, it tilts, you have a fence to use as a guide as well as the miter gauge, and the disk can be moved towards the wood, and a variable speed function.
All that makes for an excellent disk sander…of course if all you had were the disks, then the project makes perfect sense. (naturally, being a Shopsmith nut, I’m going to add something like that, I just can’t help myself)

What speed does the motor run at and what HP rating is it?

Lathe disk sander in ShopNotes issue 49 is a good one if you have a wood lathe standing idle.
Could have multiple disks with different grits. If you have a variable speed lathe all the better.
Only cost would be an extra 6” faceplate.

I think the motor is 1/3 hp and probably 1750 rpm.
I know I can stop the motor with enough pressure on a piece of wood.
The bearings are green and 3/4” ID. Sorry, so long ago.
Went to Kaman bearings and described what I was trying to do.
I built the two motor boxes and found the table plans much later.
My shop is only 11’ x 12’ and I wanted a beefier lathe and a bigger table saw.
Something had to go.
I count the patio as part of my shop in the summer.
