(Part - 1) I am having trouble with my rotor not holding my beam in position during wind storms. The beam wants to turn such that the boom is pointing into the wind and the elements are broadside to
The Tailtwister (big brother of the Ham IV) has a pre-drilled hole through the upper rotor housing and clamp piece. I'd pin the mast with your rotor, just as is done with the T2X. 73 Don N8DE _______
I never tried one of these but they get good reviews, http://www.tennadyne.com/slipp_nott.htm Joe - KC2TN Sent from my iPad _______________________________________________ ___________________________
Looks like a good solution and easy to install ! Bob K6Uj _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.c
Pinning the mast to the rotator is a sure way of preventing mast slippage. It also puts you at risk for rotor destruction if the wind load becomes overly excessive. Since there is no good way of pred
The idea of drilling and pinning seems like a real good idea but there are drawbacks. I have been tempted on several occasions but have always backed away. I just seems like not having it pinned give
Someone suggested to me that I might increase the mast to clamp friction by wrapping the mast with something with a little bite. Do they make double-sided emery paper that can tolerate being wet? I h
You probably don't want to hear this, but you're really pushing it with a Ham IV turning 12.1 sq ft of antenna. I agree with Roger that the ratings on these rotors are generous, and they really need
Some manufacturers supply adhesive backed grit stuff that looks like what is used on metal stairs to give them some grip. Probably stuff like this: http://www.amazon.com/Incom-RE3952-Safety-4-Inch-15
K7NV makes the same observation on his web page, Dick, and suggests that if you want to pin a mast the hole needs to be drilled very precisely and a pin specifically designed for this purpose be used
I have to agree with WC1M that you're pushing the limits of your rotator. You probably could improve the clamping if you added more u-blots to the clamping plate if that is possible, even one more in
Ideally you polish the bolt or use a pin and ream the hole. Use the largest bolt or pin possible without weakening the mast (more contact area.) It's almost impossible to just "drill" a hole and get
