Interesting article...lots of "how-to" and theory, but no test data of sewn joins. Oh well.

knotty wrote:My personal experience with sewing with nylon thread(including spider line)is that it cuts the fabric. I've made backpacks, sleeping bags, tents, sit harnesses, dog backpacks, gators,and so on. Ive experienced failure under stress when packs are overstuffed, tents in high winds, and I personally have given up on nylon thread. As the fabric gets older and starts to degrade, it tears at the thread(even when new but more when it ages).
I prefer now to use quilting thread and have had no problems with the thread cutting the material.

I ran a number of tests on the machine and broke a number of different stitch patterns, webbing, thread type etc and got results that were similar to what other folks have reported. I should have published the data but got busy doing other things. I still have the webbing and printouts in the basement but I don't know if I still have the notes available. I've been talking about rerunning some of these tests to try and isolate the variables. I do know that I got to the point that I could predict the strength of stitching on new webbing pretty closely.
