Hi Pierre,

Actually, Strokes per Minute are a function of the Bull Gear rpm, so they stay constant for each speed range. That means the ram travels each stroke in the same elapsed time - there fore, the longer the stroke, the faster the ram moves to cover more distance in the same time.

A longer stroke makes for a faster cutting speed (or technically, a faster max cutting speed as it varies from 0 to max to 0 on each stroke).

The Gingery Shaper, for example, in "first gear" has a CS of 5 1/2 ft/min at 1 inch stroke, but CS is 33 ft/min for 6" stroke - still in first gear.

Aren't shapers fun!!
