Just curious if anyone has used either of the products here, http://www.lecryo.com/index.html. I wish there was more information on the site because it looks good in theory, but does anyone have any real world experience?
Don't cyro treatments increase the wear resistance of a metal?quote:
Deep cryogenic processing permanently refines the grain structure of metals at the atomic level. Carbon particles precipitate as carbides into a lattice structure and fill in the microscopic voids. This creates metallurgically improved and stabilized rotors that have a denser, smoother surface. As a result, you reduce heat and wear on brake rotors and pads.
Detour begins:quote:

As for NOS (new old stock) tubes from the likes of Western Electric, Mullard, et al, I really wonder how much of this stuff may actually be months old - not decades old - and coming in from a Peoples Republic Army factory on the outskirts of Shanghai in beautifully counterfeited boxes mimicking the original brand versions to be sold stateside for fifty, seventy-five, or even one-hundred-fifty bucks a pop to the cash-flush and naive.
Correct. That is one situation where vacuum tubes are superior to their less robust semiconductor cousins. It had nothing to do with Soviet technical "inferiority". They had plenty of transistors, too. But that is why tubes still are sometimes found in military applications.quote:

I remember reading about the capture of a MIG fighter aircraft years ago, and the amazement that its avionics were vacuum tube. Then the reason dawned.
I participated in several atmospheric nuclear test series and saw the effects of EMP . . .
Amazing what people will do to fleece others. Next time offer to pay a dollar in cryo treated nickles.quote:

I had a barrel cryo treated on a rifle in the mid 90s. It was supposed to help out accuracy thru better barrel harmonics. Nothing in accuracy changed other than my wallet was lighter.
