I have the manual mitre sander and love it but I was just wondering which sanding discs everyone is using? I like to use 10" discs(100 grit) as they are cheaper than the 12" but United doesn't sell 10" discs,
so the questions are:
1. which size disc do you use?
2. Where do you buy them at?
3. What grit do you use?
Thanks,
Goyo
 
Why don't you try some of the woodworking catalogs? They usually have much better prices than framing suppliers as they are selling a large quantity of them to woodworkers.

I don't own a miter sander but have done woodworking most of my adult life and, if truth were known, you could glue a 6" or 8" sanding disc to your hand sander and get similar results for alot less than 10" or 12" discs. Granted, the discs wouldn't last as long but you may find them in larger quantities for a competitive price.

You could even go to an auto supply wholesaler and probably get a whole roll of glue-on opencoat discs (5", 6", 8", and 10") used in the shaping of autobody plastic filler (40, 80, 120, 150 grits) and for a few bucks more, you can get some self-adhesive discs by the roll. 3M is the leader in that field but there are also off brands that will do a good job.

A word about sanding discs .... I had been using a cloth 80 grit with my ITW/AMP and was happy with it until subsequent discs turned out to be of unequal thickness, causing an uneven sanding process .... the thing kinda "bumped" while sanding (yeah, it blew me away, too...
. My distributer advised that I switch to paper discs, stating that the cloth ones were not designed for the sort of precision sanding we framers require .... and they're cheaper and of uniform thickness.... problem solved. True, they can be a little more of a challenge to remove, but not bad.
 
good point, FF. Most of the self adhesive disks that I mentioned have a high tack but easily removed adhesive on their paper backing. Most bodyshop sanders run at very high speeds so the disks have to stay put or you would be ducking 80 grit frisbees whenever you started sanding a panel.

Most professional sanding materials are made to a higher standard than the average DYI stuff sold at the BB hardware stores and wood supply places just as our adhesives and papers are of a much better quality than many of the across-the-counter materials. Like many of our supplies, you pay a bit more for them but you get the higher quality in the bargain.
