Bruce is the best person to work with on these.
Prices fair, machine work excellent.

I'd like to fit them on Jensens for sure. Down the road perhaps Empire, Mamod, or Fleischman. I also want to create a two- or three-stage speed reduction accessory not unlike the one Empire used to make.

I have a good drill press so I can bore things out a bit if a larger shaft is needed.

Thanks,

Paul

Aside from machining them from scratch, is there somewhere to purchase cone pulleys, also known as step pulleys?
What are you wanting them to fit ?
