Hi busted
I to managed to use some old parts around the house and made a speed reducer, but now I need another. I could do the same thing that you have done but I think you have done one thing I can't , as I can do no milling and we do not have a local machine shop anymore. Did you mill out the shafts and put sealed bearing in and did you pin the two pulleys together? Please correct me if I'm wrong and if you could suggest a way I could do this, please explain because your setup is great.
