Hey guys, new to the forum as i am a hobbyist. I have a Bridgeport mill with what seems to be an import Variable speed head, I finally got it wired but now i have the issue of a missing spring on what im assuming is a sheave setup with a spring. Would somebody be able to point me in the direction of the correct part i need to get the spindle rotating? at the moment i have no tension on the belt because of the missing pieces.
Thank you in advance.
