In a previous thread I got help modifying my belt/disk sander. I needed some new 6 inch disks for it so I got a slightly finer grit than the previous 60. I settled on a pack of 100 from Harbor Freight and a pack of 120 from Menards. Someone mentioned on a different forum post that the lighter grits may burn rather than cut. I'm wondering what any of you may have found. I use it mainly to square up pen blanks so don't get too aggressive but I can understand how the speed may be an issue with a heavy hand.
