Rigging straight timber

[vduben]

if the half hitch is set right followed by a running bowline then there is no reason for it to come undone, if in doubt cut a notch or put in another half hitch

[Bundle 2]

marlin spike- surley that is weaker than a half hitch due to the tighter bend of the rope? I'd not recomend it.

 

As for not using the running bowline- can you say why

 

Check your Art & Science of Practical Rigging sir....I think you will find this knot used for this purpose not only here but in numerous articles vis a vis rigging techniques.....?

I allways use a steel crab as a running bowline and if its really small diameter limb or very smooth bark with no pegs then a half hitch aswell.

 

Very quick and has never came undone (yet)

 

are they meant to be loaded this way, i'm sure on other forums this has been discussed.

I would say it depends on whether you are shock loading the krab or not.

 

Nice pics Rupe.

No they are not, but it works well! Its referred to as knotless rigging, works a treat but for smaller loads than you might usually use.

 

By adding a half hitch you take some load away from the krab so you can rig larger bits then. Alway check the krab if it gets twisted it will need replaceing and if you are over doing it and replacing krabs too often you'll soon stop as that will get expensive, but having said that it takes quite a lot to twist a steel krab so if your using this method with a small (12-13mm) lowering rope then you will probably never get in any bother!

The rope would snap before the krab got damaged. Its a nice heavy duty strong little fella.

 

Saves loads of time deffinately worth a try

I know the system and i've used it. i was hoping to open some discussion on it. are carabiners rated to take the load at an angle to the gate? i've seen pictures of carabiners that were not closed properly and heavily loaded.

I've used that system for the last four years with the same crab, it hasn't been changed. No damage or bending at all. When I get down to 6 inch stems or so, I used a basketed sling

 

But saying that, I never shock load heavy loads, the lad I use for lowering on big jobs can lower anything from terminal velocity to zero without some much as one shake of the tree.

 

IMO the loading on the crab very much depends on how good your lowering man is.

Is that a trick question?

 

Cos I only tied in once.

 

 

Rupe,

 

you seem like a good climber, can't understand why you would post a pic of yourself cutting with only one tie in point. On a big piece like that there's no excuse for not flipping your secondary lanyard round the stem below where your cutting. Or am I wrong?

 

It just doesnt add up - all that quality gear, great rigging techniques but no second tie in point?!?

[Arborlord]

If you have a steel core your pretty safe so long as you dont rev the saw into it.

 

Using another lanyard choked is always nice but sometimes you wanna move quick.

 

After all were running businesses not training days
