Flat Belt step pulley
I'm looking for a source of flat belt step pulleys.
I've searched around all the usual suspects (MSC, McMaster, Grainger) The few flat belt pulleys I can find are single size ones. Any ideas? I'm playing around with a lathe design (older style lathe) and at this time do not have casting ability. |

Flat Belt step pulley
There are myriad of cog belt pulleys available. Could probably stack a few
of those to get a multistep. Probably better traction than a smooth, anyway. Respectfully, Ron Moore wrote in message oups.com... I'm looking for a source of flat belt step pulleys.

I'm playing around with a lathe design (older style lathe) and at this time do not have casting ability. You really don't need to cast them. Depending on the size wood will work well. Too small or too narrow are limiting factors for wood pulleys. You can make good pulleys out of maple. Laminated maple even better. Other hardwoods as well.Turn the hub out of aluminum and mount it to the wood using epoxy and screws. The screws really only help when the epoxy is setting up and if the epoxy ever fails. You can either use a large diameter hub or use a smaller diameter with large diameter flanges. I'd go with the flanges. One way would be to drill and tap holes into the faces of the hub and screw the flanges to the faces. The hubs can be keyed easily because they are made from aluminum. Be sure to finish the wood with a product that not only seals but also wears well. I imagine some kind of floor stuff would be ideal. ERS |
