Sewing cinch straps

[Tree Reaper]

I want to stitch a 10,000 lb. cinch strap, what thread and where can I purchase this thread?

Thanks.

[Dwight]

If this dude is going to hold 10,000 pounds, . . . how wide and thick is it going to be?

May God bless,

Dwight

Don't. That's my advice. Buy a rated/tested/approved strap. Logging is deadly enough as it is, without guessing if a home-made strap will hold or not.

Dwight;

The straps webbing strength is 10,000 but the working limit is 3300lbs.  The strap is 1/16" thick by 2 " wide.

These are not for resale but my own non critical personal use and I'm well aware of load limits.

I'm just looking for the proper thread to use in my CB4500.

How many layers are you putting together, . . . or are you talking about sewing straps end for end to make a much longer one?

Spectra webbing and thread are used in some high strength factory  -made climbing slings and runners. It is stronger than nylon, however has very little stretch, which is a big disadvantage in a dynamically loaded situation, such as taking a fall on a piece of pro attached with spectra webbing. Also, the slings I have used were put together with multiple bar-tacks, but this may possibly be a manufacturing expedient. I believe you can find a lot of technical discussion about webbing construction over on the parachute forums, those guys have very specific specification about what they build. It's possible that you might get Russ Walling over at Fish Products to talk to you about what he uses to make his climbing gear (best on the planet) but he might just see the big red "liability" light go on.

Nobody ( with any sense ) is going to say anything which ( should anything go wrong at any time with a strap that you make ) might come back to bite them..blame always looks for something / someone, to stick to..and then there are lawyers, who for a cut of the proceeds, will try to make anything stick to nothing, and ruin everyone in the process.

Just a loop on one or both ends.

Hopefully I'm too far off to be sued but make sure if your stitching webbing that you don't use any leather point needle as it will cut and weaken. A point only style I'd recommend.

Don't let me assume to tell you how to run your railroad, . . . but the devil would be handing out ice cream cones before i would lift 3300 pounds with a 2 inch wide Walmart belt, . . . which is what you are advocating here:  1/16" by 2" wide, . . . is nothing more than a 4 oz strap. 

Scary !!!!!!!!!!!
