I have just purchased my first lathe an old ml7, all is working great at the moment except getting the power feed to engage, i know i am missing he outer belt cover which i will have to buy. But what actually engages the power feed and holds it in place as mine at the moment just falls back down if i engage it with my hand? If anyone has any pictures of how theirs works that would be great. I know the pin adjustment can disengage, forward and reverse, but is it just a case of the bolts coming loose at the bottom?
