Storm work

It's kinda hard to explain without pics. Maybe Sohner has some?

You start with an open branch union or out on a more horizontal limb, as in the 3rd pic. Tight "V's" won't work. Throw your string where you want the SRFC placed. Find the middle of the lowering line and tie that onto the string. Pull it threw and over the branch (so you now have 2 parts of rope on either side of the branch). I find the CMI 5/8" arborist block works the best for me. Install the middle of the lowering line (bight) rope in the block and hang the block upside down. Take a 2nd rope and install it in place of the eye sling, loopie, whatever and go around the other hanging 2 parts of rope. Tie a stationary bowline large enough to go around the anchor limb and choke off. Pull the block up, into and over the anchor limb and the stationary bowline becomes choked. To retrieve, pull on the hanging 2nd rope.

Like I said, kinda hard to explain without pics or watchin someone actually do it. Ken Palmer walks through the process in the Art and Science of Practical Rigging video's.

It might be kinda hard to see, but the block is 'choked off' with another rope using a 'stationary bowline'. Sohner (Robert) showed me this technique at a TCI Expo quite a few years ago. He called it a "Static Retievable False Crotch". This system only puts 2X force on the anchor, and it can be installed and retrieved from the ground with throwline string and 2 ropes. It's definitely worth knowing how to set up.

I'd love to know it if you feel like tellin!

Is the main advantage the 2x less force than doing with just one rope and the pulley?

I would also like to see this. I think either Arbor Age or TCI showed this in the late '90's but I forgot how to rig it.

Now that I think about it, I think Pete Donzelli showed how to do it in a series of rigging artciles he was working on when he died. Anyone know if these articles are still available?

wow...that is incredible work. I get confused just looking at all those lines... one question: Why wound dressing?

 

[Norm_Hall]

Mostly for cosmetic reasons. We have oak wilt here, but it historically has infected only red oak. We put it on for precautionary measures.

What substance is the wound dressing?

kman, the video norm is talking about walks you through it very clearly. last time i checked i'm pretty sure wesspur rents out the dvd. yes you read correctly, rents. worth buying it though, for sure.

It comes in 12 oz. aerosol cans. It says 'Tree wound dressing' on the can. Never took the time to actually check out the ingredients. We have had very good luck using it on American elm and red oak during the growing season.

I was thinking it was the ISA "The Art & Science of Practicle Rigging" series. I looked it up on the ISA site and they have the video series on sale for $89.95 with the work book( https://secure.isa-arbor.com/store/The-A...r--P147C48.aspx ) so I ordered it. It came to around $101. with shipping.

Treekote is the name of the product. Here is a link to the MSDS.
