New to repairing a Columbia machine
Posted: Sun Feb 07, 2021 5:16 pm
Hi -
I am trying to repair a Columbia AT. Whenever the horn is on, the feed screw makes a clicking sound and the carriage does not advance. When the horn is off, the carriage advances properly for the most part. I am using the proper small lightweight Columbia horn. I have fixed this sort of problem in Edison machines by adjusting the half nut so that it maintains the proper tightness against the feed screw. But I have never worked on a Columbia cylinder machine, and I do not know how to adjust the machine to fix this sort of problem. I've lubricated the feed screw and carriage rod and the carriage moves smoothly, so I do not think that lubrication is the problem. Suggestions?
Thanks!
