Modify the thin drive wheel from Treadmill

[oldwolf]

IIRC, some of the guys used the old flywheel and projecting grooved drive stub to press fit a drilled out pulley onto. Three bolts were added to keep it tight to the steel flywheel.
One British chap use a wooden wheel he turned on his wood lathe and the old steel wheel and stub was epoxied into the recessed side. He trued this assembly up while running on the motor, and made it a 2" wide drive wheel.

Yeah. thanks Stacy. That's what I was looking for in my first post. Good ideas.

the simple way to prevent dust is buy one of this

with smaller holes and cover the fans. Stick a neodymium magnet on top of it to attract metal dust.
for the drive wheels you can just glue some pieces of Fly-wood or MDF together they are hard to break and easy to make than a chuck of wood.
