Lost two days to a stuck fly press arbor this week

Spent Monday and Tuesday chasing a seized arbor in my 1940s fly press, soaked it in kroil, torched it, slapped it with a 4 lb sledge, and it finally moved a half inch before the threads stripped out, so has anyone else just given up and converted to a hydraulic setup instead of fighting old cast iron?

You ever notice how old machines have a way of making you feel real smart until they turn around and bite you? Sounds like that arbor just wanted a little more respect before it gave up the ghost. Honestly, converting to hydraulic is like calling a tow truck for a horse that threw a shoe, sure it works, but you're never gonna hear the end of it from the guys who still run theirs with a prayer and a cheater bar. That half inch of movement before the threads gave out is the machine's way of saying "good try, but I was born before your grandpa, so who's really in charge here?" I say keep the old girl as a paperweight and go hydraulic, just don't tell anyone you gave up. The ghosts of machinists past will haunt your garage for sure.

That "born before your grandpa" line hit me right in the gut. I've got an old South Bend lathe in my shop that I swear has its own personality, and it's made me feel like a genius one day and a total idiot the next. When something that old finally lets go, it's not just a part breaking, it feels like losing a grumpy old friend who never said thanks but always got the job done. I get why you'd want to keep it as a paperweight, that's basically a memorial at that point. And hey, going hydraulic doesn't mean you gave up, it just means you're smart enough to know when to stop fighting. But yeah, don't tell the old timers, they'll never let you live it down.
