Hello to everyone; New forum member here and this is my first post (and I am a novice at machining). I was given an old Atlas 618 lathe by a friend who passed away and I have taken it down into parts for rebuilding/refinishing. The old countershaft hanger bushings (or bearings, if that is the correct term) were so worn and the countershaft spindle so scored and worn in spots that I ordered a new spindle and bought two bushings from a local bearing supply house. I pressed in the bushings and rigged up a setup on the lathe using an angle plate and bolts (Chinese 9 X 20) to hold the spindle holes/bushings in line with the lathe axis but the countershaft hanger slipped while boring through the first bushing (which I did by turning the lathe spindle -three jaw chuck attached- with a spindle crank in the lathe). I stopped there and checked the new spindle in the bushing and it was a tight fit, and "looked" straight, but it is off by about 1/16" when pushed over to the other bushing. In other words- the two bushings will not line up. So my question is; can anyone suggest a rigid setup for holding this oddly shaped piece (the countershaft assembly) on the lathe cross slide to bore new bushings for the countershaft spindle? I am wondering what kind of fixture they used at the factory for this job. And by the way, I used the hand crank rather than boring under power because I was afraid the reamer would do damage to the part if the part slipped while being bored under power. Thanks for putting up with my long post!
