  3. Pope Spindle, (Taft Peirce), rotor removal to get at bearings.

    I originally posted in the Taft Peirce Machine forum but someone informed me that it was probably a Pope spindle so I'm sticking it in general.

    When I replaced the bearings almost 30 years ago I...

    We just checked the similar existing fixture and all parts are slightly magnetic so could I assume that they are probably 304L? Certainly 316 would be non-magnetic and 17-4 would be more than 304L.

  7. Micro-Centric air chuck, 6" 3 jaw, I'd use it on the mill

    I have a 6" Micro-Centric 3 jaw air chuck that is surplus to my needs. Serial number 10713 so it is not that old. I put new O-Rings in it years ago and didn't need it as I found two Northfield...

    Yep, it was a bit cluttered. But it does show how easy it is for mis-information to be packaged in a cute way which might make it more believable to the un-informed.

    I was quite skeptical before I drove a Leaf also. But after buying a used one I realized just how good of a solution it is for local / regional driving. It cost about the same as drying a load of...

    "A lot of the fuel not needed by an EV is diverted to generating electricity to fuel the EV."

    Not quite. You might think that we still use oil to make electricity in the US but practically zero...

    Thanks Libor. Nice looking part. We are working on some variances and things may not be as bad as I was thinking. What was that machined on?

    That would work, but it would be nice to have it with a .750 diameter and not so long.

    This is a part that is about 300 grams. Your business sounds like mine. Liquid nitrogen... any change to the properties? I'll have to look that up. Any published sources?

    We're also looking into getting them blanchard or double disk ground. That is probably the best way, comments?

    Flat is not that important, surface finish is. Going in high vacuum. 32 will most likely work fine.

    I could get it close to thickness first, then flip flop it. But holding it becomes the issue....
