Hello Group- just found you :-)
I have a new-to-me' Rockwell 3400 lathe, Ser# 142467- is there any way I can pull a mfg date from that serial# ?
After several days of soaking it in penetrating oil, I finally managed to get the live centre out of the tail spindle- is there a way / trick to get the bearing out to replace it, or is it a toss-and-new ?
thanks
