I've been wanting to purchase a Klingspoor sander for some time and finally did so. I bought the 6" because the larger ones would interfere with my dust collector. I spent last evening breaking it in on some scrap wood. I had been using a Scotch Brite 2" ball and it did fair. I can see the Klingspoor 220 grit can be quite agressive. I'll have to be gentle. It seemed to me I still need something for de-fuzzing small areas. I have several Dremels which work but are not that convenient, having to hold the Dremel in one hand and the scrolled piece in another. I had sheets of Scotch Brite left over when restoring a milling machine. A sheet of Scoth Brite, sharp knife or scissors, a 1/4-20 bolt any length, two 1/4-20 nuts and two fender washers. I used just one layer of Scoth Brite but they could be piled up to make a thicker unit. Instead of punching a hole I just cut an X near the center of the pad with a knife. It works beautifully in narrow slots and other small areas. The grey pad is less aggressive than the green. Scotch Brite is readily available nearly everywhere. I bought mine on Amazon. It's a cheap little device and works great. Scotch Brite can be sometimes stolen from the kitchen but you did not heard it from me.
