Logs for wood burning are difficult to saw up, the best ones being
composed of denser wood, and in my experience some females
have great difficulty sawing through them.
See-Saw, She Saws solves this slightly obscure problem.
The fact that it requires two people to operate it, and is
mechanically
complex (needing constant maintenance) qualifies it
as a fully fledged candidate for inclusion here as a halfbaked idea.
The principle is simple and straight forward. A standard
playground see-saw's up and down reciprocations are converted
via mechanical links to that of a rotational motion, then
eventually to a sawing action. If you think of the links that
connect the drive wheels of a steam train to the pistons, you can
begin to understand the mechanism.
The end point of the apparatus is a large horizantally orientated
saw, poised over a V
shaped supporting base, which clamps then retains the logs as
they are being cut.
The logs themselves are stored in hopper, containing a
ram device that pushes them along in six inch incremental steps.
ie as each log end drops off having been severed by the saw, the
next section is pushed into place. A cam controlled link that
harvests some of the see-saw's action enables this to be an
automated, hands free process.
There are several advantages to the See-Saw, She Saws:
1 It delivers consistently cut logs with minimal effort.
2 It's fun to use and watch.
3 It doubles up as an exercise machine
4 It's totally safe as there is zero human contact with the saw
blade.
5 It means that giggly girls can jump up and down and cut up logs.
Delux auto version has a "raised boulder" attachment.
This features the action of the See-Saw, She Saws being used to
raise a large, heavy stone many feet in the air, where it is locked
into place. This then acts like a storage battery for the potential
energy, which is released via an escape mechanism similar to that
of a large pendulum clock. This can be used to totally automate
the sawing process or to drive any other connected devices
