basis method for pulp chips and fuel, where it is used for a one-time point estimate of what fraction of the whole is usable fiber (or fuel) and what fraction is wa-ter. As you will note, in the example provided above, the OD basis moisture content can (and will) exceed 100% on occasion â this is NOT an error â it simply re-

If the head or block being resurfaced is harder, high silicon content alloy, the speeds need to be slowed down a bit: 690 rpm for a 11-inch cutter, 580 rpm for a 13-inch cutter or 540 rpm for a 14-inch cutter.
