Disk Sander Homemade 20"

Looks great!
What did you use for the disk and are you going to add a miter slot?

The disk are made of MDF. I don’t think to add a miter slot.

How fast does it spin? With that gearing I’d guess 4 million RPM.

-- Wood is awesome.

The motor 3000 rpm. The disk about 600 rpm. I think that is necessary more rotation. About 1200 rpm

That’s a nice shop built machine.

Very nice. How did you balanced it? Also, where did you get a large sheet of sandpaper like that?

-- Joe - I am not entirely worthless, I can always serve as a bad example.

I like the stand bellow, also. It looks like little woodworking bench.

Nice work.

This may be a completely stupid question, but what is that black piece that you put on the shaft at 4:18 in the video called? I want to build something like this, but I don’t know what term to use in my searching.

I calibrated with iron weights, but does not appear in the video, I think.
I get the sandpaper in Portugal: “Indasa”
