3520b powermatic owners help please!

[sgt374]

I am rebuilding a powermatic 90 lathe. Removing reeves drive and replacing with new pulleys and vfd. I want to set it up like the 3520 so.... Can any 3520b owners give me the pulley sizes for high setting as well as the highest and lowest hz reading on the vfd? Same information for low also. Thanks

Keep the reeves drive along with a vfd. It will allow you more options with speed. I have a 1976 90 with reeves and a teco fm50 vfd it works great. I am working on riser blocks for it to give me the bigger swing. Good luck

Thanks for your input, but after lots of research I have decided I would be better off without it.
