If you've already got the 5/8" sling, just get the CMI block. That one is a good, solid block with no frills. I like the SS version but it's about $15 more if I remember right.
 
i dont have a block that will accommodate 3/4 ropes. so i think im gonna get the 3/4 block and sling combo and that way i can still use the block for 5/8's and then have room to move to a 3/4 when things start to get heavier.
 
All I can say is whoopie. lol

Really Josh, splicing tenex is real easy. Don't shy away from splicing your own stuff.

Great thread!

The 2 ton block will accept a 3/4 inch sling. Those blocks have capacity to support a sling 1/8" larger than the designated running line capacity.

Just in case you didn't want to spend the extra money on the 3 ton.

Just wondering i use 1" web slings in the tree for all my small medium stuff with a block they work great but I was looking at some rope slings single eye varying lengths and I saw you are getting 6" eyes why is that? Is there some math behind that? why not 4" or 8"? 6"eye makes sence for sure im just wondering if there's a rule for eye size?

every bit of 1600 lbs.

[/ QUOTE ] That looks about right to me too. Glad to see someone not exagerate.

Every bit of 2200 lbs.

top of the log stops shortly out of the picture frame.

controled fall, with 7/8" bull line and one big block; I think 4 ton (I'll check). 1" amsteel, 109,000 lbs tensile sling.

melted the cover on the bull line on the hobbs. got video of it. see a smoke puff rise after the run. (maybe publish this Tulip removal in two years the rate I'm going on video posting)

We pealed a spiral of green plastic off the hobbs drum when it cooled.

Nine inch eyes should be minimum for rigging.

Reason: the more rope that is "in the system", the more rope fiber there is to help absorb the shock. So, the larger the spliced eye, the more rope there is to absorb shock. We proved this during testing. Smaller spliced eyes were breaking at lower numbers, consistantly.
 
thanks Norm but then for lots of climbing gear and such they make about a 1" loop around a thimble shouldn't that drop its rating way more?

Climbing gear, if used for climbing, won't experience near the shock load of riggiing gear used for rigging. My BF2 bridge has very small eyes (about 1/2") sewn in it.
The tests we did were on double braid rigging eye slings pulled on a 150,000 lb. tensile testing machine at a rate of 4" per minute until they parted.
