Thoughts on a disk sander? Something worth buying or not so much? Small shop. If yes, what size disc?

Depends on what you are making. For most people a disk or belt sander is their least used tool. For others they use it every day. For a hobbiest who needs it once every so often, folks like the convertible ridgid spindle/belt sander.

It depends on the sort of work you do. I have
had a few over the years.

I don’t have one now and sometimes want one
because I do tricky compound angle chair
joinery. For making mitered things like picture
frames they can be useful.

A belt sander can be pretty useful. They are seldom
set up with the robust tilting tables some disc
sanders have so they aren’t as useful for
sanding precision angles generally.

Consider a disc sander leaves ugly marks on the
work while a belt sander can sand with the
grain. I have sometimes used a belt sander
for shaping small parts. You have to be cautious
not to sand your fingers but other than that
the amount of control in shaping small parts
is quite a time saver.

I picked up the ryobi while trolling the HD one weekend and they were discontinuing actual tool displays and putting up pictures of the tools, so all of the displays were on 50% off & I couldn’t walk away from the sander but left the scroll saw. With it set up on a mobile table next to my spindle sander and plugged in its amazing how often I’ll walk over to it and either just clean up an edge or shorten a piece by 1/64th or a 1/32nd. For $50 I’m glad I got it, but it’s the belt that gets all of the use because I’m too lazy to move the table over to the disc side & I’ve never really run across anything that the belt wouldn’t do

Larger is better in a disk sander, because a lot of heat is generated, and heat kills paper very quickly. The larger disk has more mass and surface area to dissipate some of that heat.

If you have (or can get cheaply) an electric motor, you could make your own. Here’s my version…
