I use standard self-adhesive sanding discs. I purchase them from McMaster-Carr. I've tried everything from 40-120 grit. I tend to prefer 80 grit. 120 is too fine, and tends to clog with contact cement. 80 will as well, but you need to be careful. You could go with 60 grit, but it leaves a very coarse finish.Good info there. I have a table saw and a miter saw. I wouldn't trust the miter saw to do any kind of precision work, it's a cheapie. I'll look into the table saw disc and work on some fixturing. Do you use the regular sanding discs for a table saw, or the kind with flaps on it? Any word on how course to use?
