The Lee-Tseung Lead Out Theory

This post is in response to your bearing pictures.  Well, I have a lot of experience in this area and, I hate to say it but, if you want a high temperature bearing than you have to change materials.  Cutting a "slit" in a precision bearing will NOT improve its temperature range.  What it will do is let the metal "relax" a bit, and in this case a bit needs to be only .0005" and you have just rendered the bearing useless.  We made true high temp. bearings for the aerospace industry and they were 100% ceramic and could take 3,000+ degrees F.  This temp would melt your bearings, slit or no slit. NASA liked our bearings and are still using this technology today.  NASA does NOT slit cheap metal bearings to attempt to raise the operational parameters.  What you need is partially stabilized transfromation toughened zirconium oxide for the ball bearings and the race and the shell.  If you do not do this, what is the expression? Pissing up a rope.

PS I have over 18 years in the precision ceramic machining industry and I know of what I speak in this area.  We used to machine parts for China because they could not hold the tolerances.

Good post! Now you can put things in perspective. Surely the old con man thinks he can squeeze in some fancy photos to make it more 'official' that those commies have the keys to the energy kingdom. Now, what is your answer, old Tseung? Let's see how you can explain this? Maybe, check with Wang or Lee when you retire your current personality? Oh, I forgot, we have to wait for the medicine to wear off first!

I thought we had agreed to leave this f*cked up thread alone in future.

Sorry Hans.
I'm LEADING OUT, as Joe said!

Thanks for reminding me I need to be off my hobby horse. I'm off NOW!
I'm going to join Otto in his TPU research. I hope I don't see old Tseung on that thread!

Thank you for your information.  There is one more solution for the Chas Campbell device.
