I used a belt sander with 80, 120, 220 grit. Then, 400 and 600 grit trizact belts. Finished with coarse then fine Scotch Bright belts.
Did the nooks and crannies with a small wire wheel on the dremel. It sounds like a lot but it really wasn't bad and I enjoyed doing it.
Its instant gratification seeing the progress getting better with each pass.
The last NMSFNO I stripped, the coating came right off and was almost perfect underneath. No decarb at all, the blade was just about satin and the flats were smooth and shiny. You never know what your going to get into when you remove the coating on a BUSSE.
