Thanks for the reply. The great thing about these discussion boards is exchanging ideas, getting input from others. I enjoy the challenge of building tools from scratch or devising a different way of building them. That is the purpose of trying to locate this variable speed pulley system.
Not all of us can find a used or purchase a new variable speed motor. This is my quest for a new project. I am building large and different style bead roller and want a variable speed drive system for it.
This system was used for lawn tractor variable speed drive and it you think about the weight of the tractor and itís driver. I believe that it will transfer enough power for my use.
