Just an added note: I always use locking nuts (double nutting) on rotator mounting bolts unless they are the huge bolts as used by Prosistel. I still use lock washers and locktite on the nuts. I've n
How do you get double nuts on a bolt that has no nuts to begin with? The bolts screw into threads in the rotor casing. There's no way to double nut them. 73, Dick WC1M _______________________________
Sounds like a good argument for a second thrust bearing to keep the mast straight. By coincidence, I just installed a 2-el Cal AV 40 (a rare beast) and an M2 OR2800PX. I bought and installed the wire
Sho nuff is. I use longer bolts, put nuts and lock washers on the extended threads, screw the bolt in the proper distance and then tighten the nut against the base. Pretty it's not, effective it is.
Hi Dick, I used aircraft bolts, after I had re-drilled and tapped the holes. The aircraft bolts have wires through them so that they won't turn. I'm not sure how Roger does it. He must have a T2X tha
It's not nearly as difficult or awkward as it sounds. Take a bolt (bout 1 1/2" or 2" as I recall). run two nuts up the threaded portion to the end of the threads toward the head of the bolt. Put a lo
Nothing wrong with using aircraft bolts other than they are expensive. They have rolled threads instead of cut threads to prevent stress risers. They come both drilled and undrilled as well as drille
(bout the find off "jam If you think about it, this accomplishes nothing that a bolt would not accomplish in the same application. The second nut does nothing more than make the first nut "thicker".
In 2003, I (actually, I watched, while Bill, N5YA, and a 60 ton crane with 161 foot boom did the work) installed a US Tower HDBX72 with a 24 foot mast, and mounted a 2-el Cal AV 40 at the bottom and
Yes it does. A thicker nut and two nuts "locked" or jammed together are quite different in the way they work. A thicker nut or rather one twice as thick (two nuts) offers twice the area as do two nut
The "double nut" approach for locking has been used on boat propellers for decades. One nut locks the other and then, considering the consequences that loosing your prop can generate, the deal is fur
Oh... I guess you would not want your nuts in a jam. Anon -- -- _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contes
