What Did You Buy Today?

Somebody (thought it was Tom Lipton, but couldn’t find the video) serviced a ball screw assembly and replaced the balls. IIRC, he put the new balls in a tray with some of the grease he was using so they wouldn’t escape; this is the same thing I was taught to do 50+ years ago when servicing drives on 16mm B&H projectors - they had open bearings with ~2mm balls - after cleaning with solvent they were immediately placed in a small cup with some grease and you used a toothpick to transfer them into the race.

I need 696 ball bearings, I ordered 800 so if a few try to make a run for it I'm covered.

@ChazzC Funny, as I was reading these posts on dealing with the loose bearings I was thinking of the B&H 285/385 series then I read your comment. I cut my teeth in the camera repair business on those projectors. (1965) You know B&H made a tool (envision an ear syringe) that was supposed to suck up the correct number of balls and deposit them in place. I found it more trouble than it was worth.

That sounds like one of my projects. I needed 464 bolts, so ordered 500! Same idea.
Even a 3/8" nut or bolt can take off for parts unknown!

And what does 800 precision .125 inch ball bearings cost? A mere $32 lol

Should have FRESH vegetables next winter. Put a deposit on an 18 foot 4 season green house today. Will install it next spring. They use passive solar with a 700 gal water tank to supposably keep it 20 deg C above ambient. Will add additional heat with radiant hot water from my wood fired boiler.

I don’t think we were a full B&H authorized repair center, we didn’t have any special tools (also the boss was cheap: had some Graflex - which we were authorized for - tools/fixtures duplicated bu a local shop for half what Graflex wanted). While I was there wegot qualified on Kodak’s: needed to have an O’Scope and VTVM in the shop to troubleshoot sound systems, which we bought but never used. We also sold & serviced Technicolor projectors than used 8mm loop cartridges: very popular with Elementary schools.

Bought the big daddy headstock chuck today! Jacob's 59B.
I have a crazy idea about an eccentric lathe chuck... sort of in the Horvath vein.
Yes, I'll post about it

I had one of them for a Taiwanese lathe I had in the late 80’s; it was part of of a commutator turning kit with another chuck that was mounted on a live arbor. I think Mr. Pete has one of these kits (hell, he has two or three of everything - the only one I am aware of that has more stuff than Dave!)
