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-
Shapers spin slower than routers, usually in the 7-14,000 rpm area and their power demand starts where routers leave off, (around 3 HP). Router tables are welter weights by comparison. It takes two routers to equal one shaper.
I primarily use corrugated back or lock edge cutters which are bigger and heavier than say a 3 wing cutter. I worked in a shop that had a 15 hp SCMI shaper and we ran everything at 6000 rpm or lower. The 2 cutter head I refered to is 2 high and 4 in diameter without knives in it. With some moldings the overall diameter can be as much as 6.
