I'm building another wheel, built 2 previously, to try the throw-while
standing thing and because I need one that will handle more clay than my
present wheel. Have two questions. First in calculating gearing, what is
the maximum wheel speed necessary? And secondly, does anyone have
experience with a motorized kickwheel design using a small pully on the
motor, large (very large) pully on the wheel shaft [I'm designing it under
the kickwheel] and a variable friction /tension on the belt? What I'm
planning is to mount the motor on a gate so it can be engaged slightly,
fully, or not at all.
I would appreciate any wisdom from those who have been there/done that. By
the Way... I'm using a pickup axle and bearings, figure to do this whole
project for $50-$75

Hoorah for the "El Cheapo" I thought my family was the only one who used
that phrase!
Let me ask, Are you using a solid flywheel?? If so why not use the
Lockerbie system for the drive?? I think it would be a lot easier than the
slippage/pulley design. It would also allow the flywheel to be a lot lower
to the ground. This seems to be advantageous if you need to kickwheel
it(like when you are starting the wheel up) My mentor built a copy of a
lockerbie wheel just to see what it would take and it was really cool. Very
rugged!
Lets see, Max speed??? The fastest listed in my catalogs is around 250rpm
but for a flywheel for big work I'd stay in the 100-150 range. Centrifugal
force would have to be getting up there for the higher speeds.
Have fun, Ben
