I have been struggling with the flute grinding attachment on my U2 Checkel for over a year. After re bushing it and putting seal on it etc, under a load it’s a bust. Too much friction. It was mentioned several times by the experienced that the only thing that works is an air bearing. That’s what the real tool grinders have. So put an air bearing attachment in my long range radar. Few have showed up and usually in the $800+ range.
It had fallen to the impossible to find range until Fri in my usual search of CL from LA TO SF, down in Ventura an air bearing grinder attachment appears, for $200! Emailed to guy and didn’t want to get my hopes up and the owner, Jim called me back! He was a toolmaker for all his career and is liquidating his stuff. All in small lots. He said I was only the second guy to call and was shocked nobody had jumped on it for this price. I’ll be honest I thought it might be a come on. We worked it out and even though it was Ventura navigating Santa Barbara south is terrifying for me. Jim was even nicer in person and felt bad I’d had to come all that way(3hrs one way). So he threw in extra stuff no cost after I tried out the air bearing. Couple extra mill bits, a grinder hub. Aluminum channel and hex shaft! An air bearing is even more crazy wonderful than I imagined.
As I tried to leave he kept pulling stuff out and even though I’d specifically only brought $200 he kept throwing stuff at me no sane TAS sufferer could refuse.
First was Im not sure if it’s a cross slide or compound of a Hardinge. Rusty but tight, $10. Then as I was trying to close my car door he brings out this little jewel. It’s some kind of precision grinding fixture. All three axis are spring loaded with the x and the y with the little Lufkin mic’s for stops. He tried the “what will ya give me for it” and I told him homey don’t play that. He came back $10, doh! Said I could send him the $ in the mail. He had a really nice assortment of DI’s of all kinds and mic’s, which I’m good. But he still got me like I knew he would
