So many good things came frome these thermodynamic principles.? Internal combustion engines, refrigeration, air conditioning, steam turbines for power.Science is fun-Jody

Hi Bruce You make a good point that a low heat conductive piston might be better. Here is a video of a copper tube and wood piston type fire piston. https://youtu.be/YKJksRIBzNc I think the coolest

Neat. Aluminum is highly heat-conductive. Steel might have been a better choice. It's denser, but a thinner wall could be used, so it might come out in the wash. What's really impressive is when

I searched "spherical bronze bushing" under Google Images and got a lot of hits. I didn't follow up on them. Bruce NJ [email protected]> wrote:

Maybe not applicable in this case , but what most machinists I have worked would do is to cut the thread with a single point tool up to 90% or so , and then finish it with the relevant tap or die

Haha!Less talking and more cutting.I'm not worried about fatigue or tension stress at all on the stuff I'll be doing.? Just sharing knowledge about what I do in the aviation industry.-Jody

Good trick Jeff, I will remember this one as I encounter these "olive" bearings on occasion!? Bill in Boulder CO USA sometimes in Plano! BTW where is Lone Star?

Forget stress and fatigue just cut the thread don't worry about that stuff. You are not building a space ship GP --------------------------------------------

You're absolutely correct Jim.A fastener in tension will obviously fail at the minor diam or thread root and at the nut.? Being an airframe stress analyst and also working in the fatigue and damage

Thanks for clearing that up.? I didnt look at the cutters closely, and they just looked like straight up 60 deg cutters. I see why these would be desirable now.??-Jody

BMW parts will be metric, of course ? ________________________________ Sent: Thursday, January 10, 2019 5:46 PM To: [email protected] Subject: Re: [atlas-craftsman IO] Off Topic Question

Looks like a BMW power window motor bushing/bearing. I replaced one awhile ago; it wasn't that hard to get. you might look into Bosch, or one of the other electrical suppliers for the part.

I want to thank all that replied, too numerous to mention. The UK sites were all metric, as were the Chinese, and I really don't need ten thousand pieces. A dozen would be nice, though. I never heard

For those who care about tensile strength of screws, the root of screw threads very significant affects screw tensile strength! A sharp bottom V is a stress concentrator/riser, and defines the minor

A full profile insert makes the entire thread, flank, root and crest.? Because the root and crest width varies by pitch, they are only good for a limited number of threads.? A partial profile

In looking for an internal threading boring bar I came across this set on Shars. Shars Internal Threading Set (

Have you thought about getting one that has the correct OD and then make a bushing that fits your shaft and machine the OD to fit the ID of the new bearing.

Works? ok on one or two if you're only taking a little, after that it's down hill. Sent from my T-Mobile 4G LTE Device
