#1149: Slowsaw

When cutting up firewood, with nothing else to think about, it occurred to me that the process might be better organised.

People who want to saw wood slowly, using a normal ripsaw and a consistent action, but who have limited musclepower can make use of today’s invention.

It consists of a simple vise which grips wood of any shape in the usual way. After each stroke of the saw, the vise (and wood) is rotated precisely (using a computer-controlled motor), so that a perpendicular to the saw contacts the wood surface symmetrically.

This minimises the amount of wood sawn through in each stroke and thus the rate at which energy needs to be expended.
