On my own, I went out and purchased a bunch of 1U low profile cpu coolers and installed them on my switches. ........ I got written up for putting non-approved hardware into customer machines that could have voided their warranty.
I hate engineers.....
Engineers design things, Technicians make them work. A "good" engineer will understand his resources and utilize them fully. They will go out on the shop floor or go out to the customers location, look at how things are and then ask questions, why do you do this or do that.
Bad engineers tell you how things work and how you will use it and design it that way. They will go to the location and start designing right away, no observations... Bad Engineers then become managers....... Oh yea..... I've been told engineers make bad managers..... Hmmmmm......
Back to the subject, Locking nuts were crimped metal or altered threads, but they had a short life as each time you removed them they tried to go back to origianl uncrimpled unaltered state. First nylon locking nuts had a hole drillled into the side and a slug of plastic inserted. Nice idea, but the angle of the plastic and size , it didn't last long. The Nyloc's also don't last if used in applications of where you are constantly removing them. But for vibration aplications they're great. Oh yea.... they don't like heat ..... on a side note, I had a set where they had bake-lite instead of nylon, but the bake-lite wasn't flexible enough so they were "use once & throw away".
