i wanna start implementing the use of a figure 8 for rigging. do 8's have enough friction for rigging 8-12" diamter branches??
figure 8 for rigging?

Save the 8 for rigging for when you've used up every other device on site. Don't forget about tree wraps. I use the small portawrap in the tree. Quicker and better. I wouldn't put the 8 into my rigging kit. I don't even like using it for descending myself. Really a backup kind of thing, for quick descents like lunch time. Also if you use your 8 for rigging it should not be used for climbing like any rigging gear.

They definately have enough friction. For years (and even now on occasion) I did all of my heavy rigging on the large, crome plated figure eights. We regularly lowered 400-1,000 lb. pieces with them. Remember, on the large figure eights you can "double wrap" even a 5/8" bull rope. Also, remember that you will have to "untangle" you rope often, as it will wrap up with repeated use on the device.

I think a fig 8 is a crummy way to do the rigging. You'll be light years ahead if you can spring for a portawrap.
But if you ARE going to stick with the 8, get the biggest one you can.
Your rope will twist a lot (as wheelloader said) but I'd like to add that you can cancel out the twist (to a degree) by loading it in different directions on every other lower. One way will twist it to the right and the other will twist it to the left.
Let us know how it goes!

The mini porty is really nice if your looking for somthing that you can use in the tree.

Re: figure 8-use the OLDS
OLDS for in-tree rigging
F8's will work but there are better tools. Using a bollard in the tree can be tricky. If the down rope gets slack in it there is a chance of loosing a wrap on the out-put end resulting in loss of control. If you use an ISC FOS you can clip the rope with a biner to trap the tail of the rope.
F8s tend to hockle the ropes. One way to reduce hockling is to alternate ends on each lower.
The OLDS works really well.

Re: figure 8-use the OLDS
I shouldn't of been so negative about rigging with the 8. It will work but it's like comparing an ax to a chainsaw or an 8 to a portawrap.

I'm going to buy a OLDS Belay Tube in February, finances permitting. I think that it will have really good value.

Re: figure 8-use the OLDS
i was thinking how cool it would be to make a lowering device along the lines of the unicender. anyone got any creative ideas or input?

Re: figure 8-use the OLDS
How about this- chain links- maybe like 3" each, but cut open so you can slot the rope into it....then there are little captive eyes that keep the chain link from falling apart...
Then you weave the rope through in an "S" back and forth pattern???? Then when the piece falls it the chain goes taut and locks the load (you can adjust how much it'll slide by weaving the rope through more or less links). If it's too tight, you grab the top link of chain and pull back on it like a friction hitch....
Cool- now someone make it and let us know how it goes....

It sounds like that this could fit your description ... maybe?

It sounds good in theory to me anyway. What I've tried with chain on hand did not give good results. Larger links with maybe a 1/4 twist link might help.

Re: figure 8-use the OLDS
large twisted clevises in a chain maybe?? the only problem would be the screw gates would lock down so damn tight after shock loading.

Re: figure 8-use the OLDS
I rig with an 8 once or twice in a year of steady climbing. Not terribly refined but it works in a pinch. I keep a dedicated 8 and small loopie close by in certain situations when I'm on the ground in case someone's lowering something and I need a little more friction but I find it's best to keep in in the 2-300lb range and only for one or two times. Beyond that and I quickly set up a porty. I do NOT like to keep a climber waiting.

Re: figure 8-use the OLDS
A figure 8 has loads of uses... Yeah, its not a porta wrap, but they sure come in handy..
Heck, I even use a locking steel biner with a munter hitch for some light rigging... that makes the 8 seem like a godsend

Kristian! Its me, Paul.... remember when you came out to CA, and we all worked together on that removal job I had around the Tennis Courts? Had Sackett out, Chad was there, as well as Drew... That was the time Fred had that nasty accident.... must have been at least 4 years ago now?
