Pedal Power Project#2
The second project is starting to evolve
I've always had trouble trying to saw a 2x4 and cutting it so the end was square. I know that you are not supposed to force the saw, just relax and let the saw do the work...nice smooth rythm and so forth...I've even tried marking the 2x4 all the
way around, using a combination square. I would saw nice and slow...and as I tried to force the saw to follow the line in one place, it would go off on the other side! The harder I tried the worse it got!
Finally the only thing that really worked for me was to make a miter box large for a 2x4, (which is what I used to saw the legs for my lathe stand.)
So I ran across an article where a 48 inch diameter flywheel cut from a 3/4 inch particle board was used for the pedal driven sprocket to drive a small generator, to smooth out the 'jerky motion' of pedaling.
So here is the basic version of the flywheel assisted, hand-driven saw(next version will be pedal driven or rather 'treadle driven, of course there has to be a connecting rod between the tip of the saw and the eccentric pin. The saw you see here has been replaced by a newer saw that is sharper, shorter and cuts in both directions, push and pull...twice as fast in other words!
(Feb.11, 2003, started and scrapped for now
(too cold out there today about 2 or 3 degrees!!) look for my newest project coming soon about wind energy
