Hello! If we are to build a treadle, we need to make a flywheel that will
be level and support the crank shaft. We suppose that doing this with
concrete might pose some problems. Does anyone have experience/suggestion
with treadle flywheels?
Thanks, Lyla

>Hi, Lyla:
I just found Holden's book. Did you spot his plans for a hollow wheel
that you could add ballast to for your own touch/kick/ (p. 120) I haven't seen
any clearer directions than he has given. If I run across one I will pass it
on.
Keep in touch about your progress.

Lyla ,.. I have made 2 flywheels using laminated wood,.. I used maple and glued
together the segments then made a jig to cut the flywheel round on the
bandsaw,... then once round I drilled two holes throught the core of the
flywheel and counter bored holes into which I tightened threaded rod with nuts
on either end.... this was to further insure that the glue joint would be
supported even thought the glue is actually strong enough on its own,.. The
problem that I have found with concrete for the treadle flywheels is that it is
far too heavy for treadle,.. the flywheels I made were around 50 lbs. a
comparable size in concrete I would estimate to be at least 80?... This is only
what I have found through my experimentation. hope it helps

Before you start making something, check tha area junk (scrap metal)
yards. You just MIGHT find what you need. I did - a 110 lb. flywheel from a
printing press of some sort, weight concentrated on the peremeter, perfect
size for the kick wheel I was building. Cost $10.
Happy scavenging,

Dear Lyla
Concret flywheels are a pain because of the dead weight in the centre
which serves no real function. Suggest you use two discs of heavy
plywood with housebricks bolted in between around the perimeter like the
filling in a sandwich, then you'll have the full effect with no excess.
12 bricks around the edge of a 4 foot wheel makes it almost unstoppable!
Steve.
