Greetings, TowerTalkians -- Other than a prop pitch, the Orion 2800 is about the best amateur rotator available but I've run across three Orions in the last couple of months with the same problem. An

Learned the hard way: If you want to lock a bolt/nut you MUST use a jam nut. The cost is peanuts and it works every time without fail. Even when bolting big rotators to the rotor plate, a jam nut wil
Some other possibilities, you may have eliminated them. 1) stretch of the long bolts, detectected by comparison with new ones. 2) some small deformation of the mast clamp due to stress. 3) Mast clamp
During a conversation w Mike a week ago he said that M2 abandoned the rubber donut shock absorber because the bolts loosened and gave trouble. He also said that rotator mounting bolt loosening is a f
FYI, there are similiar mounting bolt loosening problems with HDR-300 rotors. I also double nut the mounting bolts. Bob, W2CNS@arrl.net -- FAQ on WWW: http://www.contesting.com/towertalkfaq.html Subm

Although perhaps overkill for the application, if you really, really, REALLY don't want bolts to back out, the military and aircraft industry way is to safety wire them. Two posts, one mentioning rac

I wrote earlier: It's been a while. The method I mention will work fine, but it's not the "right" way to do it. The right way is to push one end of the wire through the first bolt. Loop the wire arou
The world may have changed since 1968, but when I was working on Navy aircraft in that era, if you had a number of items to safety wire, such as bolting flanges together, the daisy-chain method was a
Wait a minute everyone. Everyone is gluing, wiring, locking and double nutting the bolts. When a problem gets that severe, you can bet something ELSE is going on besides the nuts turning. The nylon s

Agreed. But after 40+ years playing around with BIG horsepower autos I feel that stainless is one of the worse materials to use under conditions of high stress and torque. Instead, consider the highe

I have had 4 of the rotators fail, the bolts tear out from the base. It could be fixed by opening up the mold to allow more material around the bolts. The material is less than that the engineering h
