Is this what you meant Mr Bullman

[Dean Lofthouse]

sorry i think its crap and dangerous

you have doubled the load on the top anchor

so its more likely to fail

and at some point the drop will be too big and shock all the system

if you had used a seperate piece if rope from good anchor up to weak anchor and a half hitch then clipped a pulley in it would have been much safer and i would have said you actually had thought about it.

sorry if this sounds strong

anyone got other thoughts

 

Your entitled to your opinion Bob, but your suggestion would still double the loading.

 

The secondary anchor was more than happy to take the load, but it would not take a side load, side loading is extremely dangerous, the leverage and forces involved can break even a thick branch

i would have had the gate facing out.

Well spotted Bill

 

 

Also remember Bob, you only double the load on the secondary anchor when both legs are vertical, the more open the legs, the less the loading, till it is zero at 180 degrees.

it would not have doubled the loading if half hitched at the top as the rope going down to the main attachment would only be there as a in case the top anchor failed would it not

You'll have to draw a picture

What about the side-loading if the two points are not in line?

[bob]

will try to explain again

step 1 tie rope to thin tying in point with a pulley on the end (single pulley)

step 2 tie the other end to a stringer anchor a bit lower down the tree

then work of the top pulley and the backup rope is not loaded it is there as a backup if required when the top anchor failed

if this does not make sense i will take some photo,s tomorrow

 

if doing this type of work always strop on as well

Good point Pete, I made sure they were, but 20 degrees either way is neglegable side load, as long as you remember not to go beyond that. I would think on most trees branch structure would limit how far to the sides you could go ??

If you could Bob

[Steve Bullman]

thats exactly what i meant dean. for the record im not advocating this technique. its a method i chose to use on one particular tree as the ease with which it enabled me to carry out the work far outweighed the minimal risk(in my estimation) of redirecting my anchor point in this way. I certainly wouldnt recommend this technique to a new climber as there is too much to assess as well as a sound understanding of structural properties of the wood in question.
