I've found that if you have a lot of metal to remove with the 1SM, it really helps to start with a very coarse, 80 grit or less belt. If memory serves me correctly, I've chugged through a bunch of steel on my 1SM using a 60 grit Zirc belt. Those Zirc belts are very sharp and aggressive and will scratch pretty deeply, but for hogging off metal they work great.
