11/05/2016 · I've been curious if anyone has converted a variable speed bridgeport head to direct drive or to just regular pulleys or timing belts. I have replaced the belt and bushing on my mill twice in 3 years. At first it's really quiet, but soon becomes louder and louder. I'm thinking that I could just do 2 timing pulleys and a VFD. Any thoughts? thanks
· I haven't done this to my Bridgeport mill (I have a 1942 M head BP with 6 vbelt pulley speeds adn 1/2HP 3 phase motor) but I have added a tach to both of my Altas lathes I have a 6" atlas lathe with a variable speed motor setup and a 10" Atlas that I am planning on installing a variable speed setup on. Hope this info is helpful to you.
