The spindle may be raised and lowered relative to the shaper's table, and rotates between 3,000 and 10,000 rpm, with stock running along a vertical fence. Being both larger and much more powerful than routers, shapers can cut much larger profiles than routers – such as for crown moulding and raised-panel doors – and readily drive custom ...
