Hey Guy's
I have a 1967 Bridgeport that is in good shape. Because of it having a T-Ram option and being a Line-A-Mill when it was new( I have removed the optic tracer). It was fitted with a few upgrades. Chrome ways. Also has Ball Screws feed screws. Of which I can not find any info on.They look well made and designed but could use some new wipers. Would love to know were to look for parts if I were to need any. Also. Would love to have opinions on ball feed versus the standard bushing acme thread as far as vibration and problems climb milling. I plan on using the old servos for feed when needed. luckily this unit also has manual handles. Another neat feature is the handles have needle bearings in them and they can be disengaged to spin freely when using the servos. Pics of the ball screw set up. The feed tubes on on the back side in the pic.
