Straightening a lathe feed rod

[Paul Jones]

Olderdan and Gramps43,

I am sure Keith Fenner would be having a cow seeing this but don't worry because the final corrections to feed rod vibrations became almost perfect by taking the chance of doing this in place. The spiral errors are in within a few 0.001" and the feed rod is now running almost perfectly true and probably better than it is was when it was new in 1987. The proof is in the machining finishes showing almost no surface variations and even better than before I made the feed rod correction ( http://www.homemadetools.net/forum/l...7293#post23627 ). The correct approach would have been to completely remove the lathe feed rod and do it off the lathe and systematcilly making the correction with a hydralic press like Keith Fenner has shown in his YouTube videos.
