If I remember this right, a 150lb guy hanging from the end of a 4 foot bar equals 600lb

Of course few of us probably weigh 150 lbs. I could use a two foot bar. Or Frankie could hang from a 6 foot bar.

In my early years of aircraft school my instructor asked me what the torque was to put a propeller on a R985 motor? My answer was about me on the end of that bar. He didn't like that response. p.s. I was only off by 30ft lbs;D

Long ago in another life when I owned helicopters I was installing main rotor blades and didn't know if the main rotor blade grip bolt was supposed to be torqued. I called my tech service guy and asked him. He says "torque to GFT". I asked "GFT?" He replies, yeah, "good and f***ing tight!". LOL

When I was in the Army they called it the Jesus nut. If it came loose you were going to meet him.

The NC Forest Service has been running a couple of "EuroStar" helicopters for the past 6-8 years (the last of our Hueys had just wore out). The rotor hub (3-way) is a big forging in high-tech aluminum and there was an A/D to have them checked with dye penetrant for cracks. *Both* of ours had cracks you could see with your naked eye. Made our pilots feel *really* safe!

When I was in flight school a couple of centuries ago, I was performing my first preflight on a huey. The instructor half-heartedly told me to grab the "jesus" nut and make sure it was tight. I grabbed it and it came back with my hand. I new just enough to suspect that wasn't right. The IP nearly fainted. I learned the significance of that very quickly and it stuck with me.

Yup, the Jesus Nut used on Huey 2 bladed teetering rotor systems. The grips I was refering to are on fully articulated 3 and 4 bladed rotor systems. Two things to avoid making your day a bad one on a Huey, mast bump and loose Jesus nut!

When i was riding on them i was worried more about getting shot down......

Boomer · October 12, 2014, 09:51:32 AM

Ya might survive getting shot down but a mast sheared off or loosing a nut.....well, kiss your @$# good bye. Those were the days huh Ed.

Having started out as an Infantryman in the 101st. I guess fear of getting shot down wasn't so great on my part.
Or nearly 50 years has dimmed it.

Fear of getting shot down was lessened when I switched to gun ships. The Charlie and Mike models gave you the ability to shoot back. The Cobras caused those little guys to quit firing at the skinny ones. The Apache ruins a whole lot of days for them.

After retiring from the Army, I learned to really like the fully articulated systems. I spent a lot of time in Super Pumas and some in AStars and BStars. I also have a good bit of time in the 500MD. The 412 isn't so bad. The 212 caused me a lot of back pain on long days. Jetrangers nearly killed me.

Maybe we'll meet at a rally someday Boomer and compare stories.
