In reply to George Fisher:
Uh, i hadn't checked back here for a while. Thanks for the ideas.
George, i think 20kn could do for the time being if that's ok, as is not the webbing itself i want to destroy, which weighs at 36kn on single layer, but a few stitch patterns i want to test using dyneema thread.
Thinking i could do it for 3 pass levels at 6kn, 12kn and 18kn. If it holds more than that it's a bonus and would be good to see how far it goes, but even getting past those ceilings would be ok for the time being and would give time and some background data to start planning heavier tests.
Is it ok if i send you a mail?
