Soooo..... Is chad still around? Or did he find the breaking strength of his splice?

I figure it was a lovely service, buried in the family plot. Maybe they planted a tree in his memory.

I've thought about doing this myself as well. I would definitely have someone do the testing like I've linked above.

I know this is a really old thread, but I’m surprised at how many nay-sayers there are. Sure, people (arborists, rock climbers, abseil), die every year from their own made gear failing- but there are thousands every year that don’t…. As long as you’re doing it correctly….
I splice and sew my own slings and loops, and would gladly bet anyone a handsome sum that if I sent them in to Sherill to get tested, none would fail below 85% rope test. Any takers?

So easy to splice HRC, BeeLine, and UltraTech though. Under the cover, those are all just hollow 12 strands.
Personal preference I guess, but I like naked eye splices more than sewn eyes.

The OP's second try doesn't look too bad. Now I do think that since very few people try to stitch anything themselves - that is why so many are poo-pooing the idea. The way I see it, arborists are constantly doing things themselves that if done improperly, result in a fall, death etc. Just the way it is. I am a rigging engineer who frequents nuclear, DOD and DOE jobsites. We take rigging procedures and requirements to the extreme. On some lifts we have single-failure-proof cranes and rigging or else go to 10:1 rigging safety factors. No one goes under a load let alone reach under one. All sorts of stuff. But I go home and can be hanging from a single part of 7/16" rope. A single carabiner, single pulley or many other possibilities. Often one failure away from falling on my head. Certainly makes you think twice until you get used to it and/or start coming up with ways to add redundancy.
If I ever get around to playing with sewn splices, I'll dissect a known good splice, count stitches, measure thread dia. etc. Watch videos, do some reading, buy the best thread there is then give it a try. Doesn't mean I'll go around selling spliced gear but my stitching is going to be the least of my worries. That said, I'd probably rig up to a couple trees and do my own pull test to see if I need to dial in my process. I have a 10,000# digital load cell and plenty of real rigging to break a small rope and not get whipped. In rigging we use off-the-shelf equipment when available. If not then we do our homework and design up what we need. Fabricate, load test, go to work.
