A good friend of mine is a Ham who lives in Wimberly, just south of Austin, Texas. He is former President of the Collins Collectors Association and has an incredible display of Collins gear. He has a 55 foot USTower crankup with a Tennadyne Log. The log has lost its balun and it is far enough out on the boom that the log is going to have to come down to repair. He is now at the age where he can no longer climb and wants to hire someone to do the work. He also needs some minor maintenance on the tower while someone is there. The tower install was well done and is in good shape at this time -- he wants to get back on the air.

Does anyone know of good tower install/maintenance guy in that area?

Re: Tx-455 tower with HAND CRANK

I see...I thought maybe it had something to do with the cable spooling up on the drum and they mounted it that way instead of flat on the tower.an over a little for handle clearance....?

Dave:

The only reason that I can see is why you wouldn't mount it flat on the tower is the clearance from the handle to either the mounting plate or tower cross members. Your knuckles would be getting pretty sore.

I changed out the Fulton winch on the Tiltover assy for a K2550 Dutton-Lainson winch and the handle had to be shortened to clear the Tiltover assy. Not a big deal in my case as I use a drill to tiltover the tower.

Re: Tx-455 tower with HAND CRANK

Understood....why couldn't you just mount it like they do on the us 438 or the older triex or hy gains....flat and off to the side ?..I know that some the hand crank bracket was welded to the tower...but the new ones seem to BOLT the bracket to the tower to allow for removal and installation of a md75 or md750 ?

Its an older design. I installed a K2550 on AA6PW's TX-455 and it worked really well. I had to reverse the drum bolt and shim with washers. Its been going strong for over 10 years.

Re: [ADV] [CrankupTiltoverTowers] Stainless Steel Cable?

Hello Jim! The correct cable is 7x19. The rest is spot on as usual. I only recommend SS if the owner can see sea water.

7 strand, 1/4"  EHS  cable, like what's  used on   guyed towers  with pre-form dead ends  etc,   is  rated at 6700 lbs. 
1/4"   galvanized  winch cable is  rated  at  5700  lbs.   (  which I  think is  7-16  construction, or  similar,  IE:  7  bundles , and each bundle has 16  strands).  
1/4"  galvanized aircraft cable looks identical to  1/4"  winch cable, but is rated at 7000 lbs.
1/4"   SS  cable also has   7-16 or  similar construction  (  designed to  go around pulleys).  but  strength is  typ  4000-4500 lbs. 

That's a huge difference between   7000 lbs...and   4000-4500  lbs. 

Similar deal when using  SS  bolts.    SS  bolts  are the same as  Grade  2 mild steel .

If  using  SS,  you have to size it  up a bit...along with all the  pulleys  too.   IE:  1/4"  aircraft cable  could probably be replaced with   5/16"  SS. 

SS cable is not cheap...and esp replacing all the  myriad of pulleys.   You are probably better off buying the  correct sized galvanized  aircraft cable..and be  done with it.

Be aware that SS cable generally has a lesser load rating then the same size galvanized cable.
