I bought this spool for $1.
It's some military surplus stuff, but I can't find anything about breaking strength, and I'm not sure if it is poly or nylon.
I know it will hold my weight (240) and that it's 1 inch wide and about 1/32(I think) thick.
If you double it up, it looks like its 1/16th inch thick, so I estimated that it's 1/32nd.
I'm trying to figured out if it will be good for tree straps.
I figure even if not, it was worth $1.
You guys have any info on breaking strength?
I'm thinking of trying to find a way to load test it without breaking more than the webbing...
Any tips for injecting thread into the webbing would be appreciated also.
My old Singer did ok for the first couple straps, but had trouble later.
I'm thinking of sharpening or replacing the needle.
Finally, I tried something new with the pictures, so let me know if you can't see them.
