[TowerTalk] How to attach a 25/45 ginpole to HDBX Tower

[Gene Smar]

Benny:

I followed Steve's suggestion from 2001 about using a chain and a couple of S hooks to support the bottom of my ginpole on the Trylon I was assembling at the time. Here's a close-up of the bottom of the pole http://tinyurl.com/no9w45g  , along with a few feet of heavy chain and two S hooks. Note that I taped the hooks so they wouldn't fall off the chain. I lashed the ginpole to the lower leg at three places a few feet apart.  
 
A word of caution:  I would advise against this method for the HDBX design.  To use the chain and S hook method, you'd have to sling the middle of the chain over a leg brace above the bottom of the pole.  I don't have first-hand experience with the HDBX tower but understand that the leg/brace joints are riveted together. I would not put much faith in having an individual rivet support the weight of the pole plus tower section using this method.  My tower's equivalent joints are bolted together. 
 
Caveat Amateur.

if there are 
good ideas out there about rigging a Rohn 25/45 ginpole for use on BX 
Towers. 

Designing a ginpole for a tower with changing leg dimensions is pretty 
tough. My technique is to just use the pole part and lash it to the leg. 
If you're just using a piece of pipe or tubing, use a sling to attach a 
pulley to the top of the pole. Just about any piece of steel or aluminum will 
work - it's just that steel is so much heavier. 

Use a choker or sling on the bottom of the pole to keep it from 
slipping down whilst you're pulling a section up. 

Attach it fairly tightly to the leg, otherwise it'll want to move 
around - never a good idea. 

Cheers & GL,
