Tin the frame where the Babbitt goes with 50-50 solder. coat your bar and the key stock with black soot from your torch so the Babbitt will not stick on it. Install the bar, washer and centering cones on both ends and put jigging putty around the washer if needed, stand the frame on end and do the center bearing first. heat the frame around the bearing to 200 or 300 degrees before poring. then move the washer to one of the ends then do the ends one at a time. the finished bearing needs a slot so the bar can be removed without removing the cutters, the key stock keeps the Babbitt from filling this slot.

James,
That sounds like the most reasonable solution.
I need to machine the bushings to fit the frame. What I'm hearing is that the bores in the frame are precision machined. I was wondering how I was to center new bearings in the frame if they were not.....
