Just because I can doesn't mean I should - sniper - 02-21-2016
Looked up plans in ShopNotes for a sanding disc stand for my new lathe. The author says that his lathe has a 12" swing, so he made the disc 11 7/8".
I'm looking at my lathe thinking "Gee, I've got a 25" swing, I could make a 24" disc".
Then I look up on Klingspore and the largest adhesive disc they have is 20", for ~$15 each.
Think I'll make it a 12" disc. (5pk =~$15). Probably a little safer plus the smaller size will be easier to store.

I made one for my PM3520b that is 15" and Grizzly has lots of sizes. To me I like it the best because I can turn it fast or slow. I also made a 90* stand for it in my banjo which is 1".

They come in a 2 pack and if you scroll down the page you will see other grits. Also they have an adhesive back. When I sanded down the wood I sealed it with 3 coats of shellac and used 0000 steel wool. Fits and works great.

You can make PSA discs pretty much any size you want by cutting discs out of sheet material and using spray PSA adhesive.
I have no opinion how big you should make the discs tho.

I buy 12" sanding discs from Lee Valley. I attach them to a 12" plywood disc and use a 3" face plate to mount it to my lathe. I bought the face plate for that purpose.

You may want to consider these. I am in the process (sometime) of using two to the 12" (14") for sanding disc at my old tube lathe and one as the backing for a donut chuck (16") at my Nova.

Seems to me the weight may be an issue for prolonged starts and stops. I just use plywood or mdf for all my compression chucks.
For my lathe which is old and worn out I would use mdf for the sanding disc. That way I could true it up as needed. I am glad this was posted, I'm planning on a new lathe this year and a large disc would be a perfect use for the old lathe.
