First off, sorry if this was gone over but I did a couple searches and couldn't find anything. I'm considering buying this 10" disc sander but was wondering how I could make my own discs to save some dough. Any help would be appreciated,

Thanks!
 
AB, you're just asking how to make your own sanding discs? I would take my favorite sandpaper, draw a 10" circle on it with a compass or a 10" dinner plate, cut it out, then spray 3M spray adhesive on it and slap her on to the grinder. Maybe I am missing something in your question?
 
I guess I worded it poorly. I know some guys here use 10" wheels and was wondering where they get material to make 10" discs. All I ever see are 9.5x11 sheets
 
That is why 9" is the most popular size.

If you have a 10" disc, carefully gluing on 9.5X11 sheets will only have a small uncovered area on two opposing sides. It will work just fine. Aftyer placing the paper on the disc, use a bench knfe to trim it flush.

Unless you just can't handle the cost, order 10" PSA discs. It is by far the best way. Consider the time spent gluing, fitting, and cutting discs against the cost of ready to go PSA discs. probably close to a wash.
 
I would just get a 9" disk, or turn your disc into a 9" one, and live happily ever after.

The reason everyone uses 9" disks is obvious.
 
Speaking of disc sanders, what is the usual speed used? 1500 or 3000 RPM motors?
(edit) along a vfd of course.

Thanks

Peu, Most 9 inch disc sanders for knife makers use a 1725 Rpm motor. Get a reverse switch for the VFD also. Larry
 
When I built my disc sanders I used reversible 1725rpm motors. They are more than fast enough. Just wish they were variable speed. :(
 
The discs are usually very inexpensive when bought with the machine. I believe in the 9" (8 7/8") because of the availability of multi kinds of sandpaper. I have also found that operating at say 30% - 40% speed definitely helps to produce the quality of finish wanted. I have a thin cork gasket of 3/32 thickness on my discs that I have applied with the same 3M non hardening glue I use to install the sandpaper over top. For a great machine look at the magnetic disc made by Rod Nielsen.
