I jumped in to do the power bit. I have hook and loop stuff, 80 to 600 grits, and 2" diameter wheels. I also bought an angled drill with 0 to 1300rpm speed. What is the best speed for sanding? Any other tips would be appreciated.

My son let me borrow his random oscillating sander and many of these marks were no longer visible. I haven't seen the random oscillating sanders in less than 5" diameter so they don't seem to be applicable to the inside of a small radius. It has helped me create a better finish on the outside of my pieces and on the inside of the larger diameter pieces.
While I vehemently disagree with the above statement, and not just because I want to sell sandpaper, I do agree with most of the rest.MichaelMouse said:Most woods benefit little from anything beyond 320, some beyond 220. It's direction of scratch that counts.

The burnishing part will vary with the type of abrasive you are using and the grit. It may look shiny, but may not be burnishing.
pyrocasto said:I guess it depends on what wood and what you use it for. Our cabinet shop's high end cabinets have never touched anything greater than 220 for wood sanding, and get 320 between laquer coats.
Though on a piece of cedar I turned I could see a bit from 600 grit.
MichaelMouse said:Might have been the 600 on your cedar, if the light were right and your eyes real sharp, but the odds favor a rogue from previous grits or what's worse, a scratch or dent from a fingernail on a hand trying to hold a piece of paper properly. Hate that. Especially when you press one in accidentally while roughing between coats. It's times like that I wonder if I shouldn't chew 'em to the nubs like some people.

I sometimes will clean a disc and continue to use it...especially when sanding shellac sealer or something like that. I take a fine wire brush and "scrub" (too harsh a word) the caked shellac off the disc. Other times it's oil...such as tung oil...but if I get the surface back down to the grit, what's the harm? I realize that I probably lose some cutting power...agressiveness...as loose grit is shed but is there any other downside?

CTutor said:Try Industrial Abrasives their Ryno backed paper is extremely good. The paper wears out before the backing. You can get 1ydx1meter sheets of hook and loop for about $15 and make your own disks.. Works out to less than 9cents per disk
