LMAO!!!...I knew it!!!
Once an engineer always an engineer eh? Our personalities dictate how we each look at life and look at the world around us. Some are left brainers & some are right brainers & some are no brainers. This is why the CIA does detailed "profiles" on people based on their "type". Its also why eharmony.com tries to match people up by their personality. An analytical engineering type doesn't typically go well with a free spirited artistic type.
You definitely profiled yourself with this thread...but then again by my response so have I. I'll still have a beer with you at EOM though. I'm just not sure how long I can talk about crush gaskets with you however
LOL I'm no engineer - at least not a degreed one (altho I probably do fall in the "backyard engineering" area) - I was a pneumatics/propellents mechanic - I worked mainly high pressure systems including nitrogen (GN2), helium (GHe), hydrogen (GH2), Oxygen (GO2), and breathing air (O2N2). We also had compressed air on the pads and all over KSC.
Best pic I could find after a quick search - resolution not so good: The tall pressure vessels (at the bottom) was "my" stuff, plus the first little building to the right of that housed the pad compressors (2 on each pad) - Quincy 740 cfm screw compressors. In addition we had multiple pressure reducing panels up on the structure; the main ones were @ the 175' level, but many others plus the tubing & compressed air piping all over.
We also hooked up the lines to the MLP (Mobile Launch Platform - that big grey thing the shuttle is taking off from), and had panels & systems inside of that.
And believe me, I'm
not anal - but I do change crush washers every time! I often order fasteners in bulk from places like McMaster-Carr including metric and I was looking at the crush washers the same way. That's not anal, it's practical in my thinking. I do like fiddlin' with stuff tho and tinker quite a bit in my garage. My FJR is farkled fairly well, and I'm gonna do a complete do-over this winter to simplify, organize, and shrink all the "stuff"! How's that for a technical explanation!
My intent was not to have this thread "degenerate" into
if the crush washers should be changed, who does it or not, and why - just if there was a better/alternate source for the two-piece washers vs Yamaha. When I found the one @ AdvanceAuto, that told me someone makes these and they are not special but if I want to stick with the two piece washers then it looks like my choice is to either stay with my local dealer (probably a good idea regardless), order from fjrgoodies, or convert to the more common aluminum or copper one piece crush washers. I choose one of the first two...
@EOM there will be plenty of things to talk about vs crush washers, see you there! I'm looking forward to it.
