I get dibs on his UNICOR desk calendar. I can't get those anymore, not at my job anyway. I miss being able to change people's lives with a simple calendar.
If anyone makes it to the Nintendo store in Manhattan, there is a powered and functional GameBoy on exhibit that survived a barracks getting bombed in Desert Storm.
The PCL cover was a rare "find". It was ordered to replace one broken during maintenance. At the time when M models were fairly new, they shared way too many part numbers with A/L models, even though they shouldn't have. In this case, it lacks the notch for the rotor brake release AND it doesn't quite fit right. When installed, if you tighten it down the end straightens out a little. If the PCL is moved to the LOCKOUT position, it will get stuck and you can't retard it. Fortunately I caught it doing MTF preflight checks. We sent a report to AMCOM and they fixed the part number issue. They failed to issue an ASAM or SOF. A few years later Rucker had a few incidences where they torched some engines due to this issue. Anyway, this one didn't go back into the supply system because it was considered a defective part.
The tail rotor dive shaft bearing is my favorite. I spin it on my desk and the irritating noise lasts between 20 and 25 seconds. I timed it. Unfortunately, the guy who shares the office with me has a bifilar weight. It spins even longer. It takes only one or two good spins before the LMO comes over from across the hall and tells us to knock it off!

The lockpin materials were but I don't think the bifilars had anything dangerous like that.
Fun fact- look inside an old radial engine from the 1940s-1950s and you'll probably find a bifilar (two point pendulum) vibration absorber on the crankshaft. Somebody invented those long ago. I got a D- in Dynamics I and another one in Dynamics II so I'm the wrong guy to explain how the hell the things work.
Look, you're getting the calendar. Maybe he can toss in the tacks and you can be happy?
If I recall you and @Jim123 are both right. Or both half right. I recall both the droop stops and the lockpin pullers having that same dull gold color and being standard PC board answers to, "what should you not lick on the aircraft?"
There's a "your mom" joke here that would make a totally inappropriate yet epic answer in a HAC board.
Sorry. It's not the weight, is one of the bifilar bearings. A bifilar weight wouldn't really spin on your desk very long, if at all.
The droop stops are made of beryllium copper. Beside licking them, be careful when you're doing the deice checks. They get hot, and if a short exists, you can get shocked. Or so I've been told.
How many times have you told a Specialist, "Go up there and see if the droop stop is warm."They get hot, and if a short exists, you can get shocked. Or so I've been told.
I'm a little skeptical about asking Specialist to do anything. Remember, I'm in the Guard, not the "real" Army. It is rare for one of our full time mechanics to be a specialist. A weekend only Specialist can only reliably climb up on and climb down from the helicopter without assistance and with little supervisory direction. I'm pretty sure that phrase is standard boiler plate for their evals.
Beside all that, it is SOOOO much more fun to send a 1LT, 2LT or WO1 to do that job.
MTP/ME: Just get your hand close. You don't need to actually touch it.
1/2LT/WO1: Yeah yeah yeah. I got this!
-----A few seconds later-----
1/2LT/WO1: F#$%^! M$%^Fing %^%#$%
MTP/ME: (pisses pants, breaks a rib laughing so hard and tries to look innocent): So?
1/2LT/WO1: Yeah, it's hot. (blowing on fingers).
I was trying to wrap my brain around what I was seeing and what I remember of a weight, but didn't say anything since it's been 15 months since I've been up on the head.
So what is a bifilar bearing? Is it a bearing in the weight where the bolts go through to keep the weight on the....mount thingy? Everything was always smeared with elephant snot, so I never thought to look down in there.
