I think fuel gas fittings are often LH thread.

This company moved to Inventor after decades with PTC. There were also issues with the updated Windchill file management that required huge server upgrade. Maintaining a handful of PTC licenses to support access to two oceans of legacy models and drawings. that now have been migrated to a giant...

We still sell some of our parts that have been in production for over 50 years. We have patterns for many of them, made back in the day when there were still foundries in Massachusetts and the sales volumes were much higher. We provide finished part drawings, not pattern drawings. When a...

A supplier sent us a STEP file of a model they created from our drawings for a fairly simple cast part. The STEP file was Exported from Solidworks 2024 I believe, although that may not be too important. I inquired if the STEP file was AP242 . No reply yet. They also sent an approval form that...

Once upon a time we were asked to reface some used floating clutch disks from some vintage Ferrari. Maybe .2" thick or maybe less. They were worn, and sort-of flat. Each time .005" or so was gently wet ground off one face, the disk would distort to a new shape, so we stopped. The owner took the...

Usually I delete cold e-mails and then block the sender. Once in a while I don't.

May I have some pictures of the remainder of the shaft and the machine or device that "broke" it? Also some details about the service history. Would this happen to be a belt driven device ?

Dang. I was thinking when you said API you meant these folks - https://www.api.org/ I really was.

If the bronze bearing ever experience less than EXCELLENT full film lubrication you may find that a leaded bronze offers huge benefits.

Several years ago My older daughter's 1996 Honda Accord had a lower ball joint break/unseat while slowly navigating her residential neighborhood. That car had passed Massachusetts' annual RMV inspection about a month before. It was the OEM joint with over100 kmiles. Replacing front brake...

If the upper and lower edges of two spaced tablets are welded to the jaws of the fixed Stillson wrenches, AND the purple forces are applied as shown I'm thinking it may be more of a weld shear tester. If the purple forces will actually be applied more towards the center of the tablets it might...

"cut the head off" I seemed to have missed the OP saying there is an issue removing/loosening the nuts. But that does happen sometimes.

Do you have a project, or is this just curiosity? I think any torsionally flexible coupling would "reduce dynamic stress levels", no damping required. Unless a torsional resonance is involved, and then a big whiff or two of damping would be desirable.

If I understand the "ball groove" correctly, it is the four shallow grooves that run the full length of the socket. I don't think their purpose is to affect loosening. I think it is to ease manufacturing. I think they first drill a hole down the center to remove a bunch of material to make it...
