Oh, dang. Behrens made a sick lightweight and curvy wristwatch. Even if it was free I couldn't wear it but as a machine-minded person I love the stuffing out of the engineering, manufacturing, and aesthetics. #horology#machinist https://youtu.be/GOqzjrPnWao
I'm looking for anyone who has a Pratt Burnerd lever-closing collet chuck of any kind, and/or anyone who has a manual for one. Pratt Burnerd don't seem to keep them on their web site; fair enough, this has been out of production for decades. But I'm crazy enough to have bought what is apparently one of the few D1-5 PB LC-15s ever made (because I wanted a collet chuck with similar capacity to my spindle) and I'm trying to bring it back to life.
Photos or scans of the manual for any of their lever-closing (or maybe even pneumatic-closing "PC") chucks, or any teardown pictures or videos you know of, would be helpful. I'd like to be a good steward of this piece of machining history.
If you know how the "release key" works on Pratt Burnerd lever-closed collet chucks, even if you don't have any form of documentation, mine does not seem to be working and I could use help understanding how it should work in order to proceed with disassembly and cleaning. #machining#machinist#lathe
A question for every #machinist more skilled than me (just to avoid to write "all").
To support parts that have to be rotated wouldn't be better to have a machinist #jack with a rollers head, like photo 2, rather than with a flat head, like photo 1, which moves every time the part is turned?
Hey, shop folks. Do you use software to manage jobs, stock, etc? I use spreadsheets and whiteboards and really enjoy not using the computer for planning but of course I wonder about ERPs like Proshop and Jobboss. If there was a FOSS ERP I might give it a whirl. #machinist#shoptalk
If you're a #machinist near #Seattle today or tomorrow between 9am and 2pm then I highly recommend going to the OnlineMetals.com clearance sale. They're selling metal stock by weight at amazing prices and the selection is still good, especially for stock that is two feet long or less. I'm sad that they're closing this branch but oh wow am I happy with my new stock.
Okay #machinist, #precision#measurement, and #tool Mastodon. I inherited a collection of tools which includes these apparently-high-precision calipers and micrometers. Not totally sure what they are but listed accuracies are 0.0001 inches. My guess is that this is worth a fair bit. Is this worth trying to sell?
