rigging sling question

i hope not to distract anyone from the other thread in this forum but i was looking for the opinion of others.
recently my employer purchased an ISC Flame rigging block although we also have a larger heavier CMI block on a stable braid sling.

I would like to use the ISC block for light duty rigging, but it will be used for "impact" rigging sort of speak, lowering small sized (around 15' at the biggest more or less) tops. would a sling make of a 16 strand rope of good quality be a suitable sling? once again for small sized pieces, as i only use 1/2 lines for rigging
 
I would use at least 9/16th stable braid, 5/8th preferably....keeping in mind that I used 5/8th Tenex for a few years with very good results just got fed up with the picking but it's cheaper and easy to splice ( not that I splice but just saying )....The Flame is a 5/8th block if I remember correctly.....
 
Using a rated all nylon sling is my choice for light impact rigging because it stretches and absorbs those repeated impacts far better than other far less stretchable slings that transmit shock loads onto the tree far more so than 100 percent nylon does.

They're relatively cheap and the best have their rating sewn right onto them on leather tags.

They come in a wide variety from 2-50 tons.

They do wear out though, like all things do, but keeping out of the sun in their designated bag or container substantially increases their working life.

yeh i startin to think i should just go with a 5/8s whoopie. i was looking at those nylon slings you were talkin about jomoco on some riggingwarehouse.com or somethin, i just want something adjustable so the block isnt like flopping aroudn or adding more distance between the load / rigging point.
 
That's why I use a simple cowhitch and sling, I like everything snugged up tight with no slop, my friend here uses those nylon slings and I don't like the slop they create....to each his own it's all good...
 
Keep in mind the lowering line should always be "the weakest link". For the flame block, I would use a 9/16's or 5/8's spliced eye sling, preferably polyester cover, nylon core. Not a fan of whoopie slings for the primary anchor point. The rigging anchor will see 2X the load.
 
Or you can do a 5/8ths tenex eye sling with some cordura chafe sleeve on it to prevent picking. I recently spliced up a 3/4 stable braid sling with 12" eyes on both sides this way I can wrap the sling around the rigging point as many times as needed then just put the eye with the block thru the other eye. I tested it on a small tree I got here at my house and it worked out great was real snug (no slop) I know it probably won't be best for all situations but it can be useful. You could also use it to choke up on another tree to run a pulley used as a redirect or a good knotless anchor point. Especially for rookie groundies who aren't good at tying knots....

Bad info Jo..
The extra play (stretch) in the slings increases shock loads, whereas stretch in the lowering line reduces loading.. FYI .. the rigging nerds with their computer models have shown that!

as swing mentions, the best way to do that is with a knot... any adjustable sling will tend to have more play than a sling tied with a cow or timber hitch...

Here's a pic... Well nevermind every f*'&?ng pic I try to post says its too large... Wtf!

Simple answer...you're trying to fit a football field onto the space of a baseball infield. Too large to fit.

Take a few minutes to learn how to edit pic size and crop so that the picture has the greatest value. Learning how to edit pics is as simple as tying a bowline.

This page is easy to use:

Or, there are many other apps or free programs that can edit pics.
 
I spliced up a couple of slings like that and use them all the time. It is a real time saver.

I also take the middle of the sling and go around an anchor point and through the two eyes. Then attach block to center of sling.
 
Genius thinking treezybreez that's a great idea. I can also choke sling to rigging point then throwthe other eye between a crotch and then hook a block to that eye.
