I have been reading through some of the earlier threads about DIY suspension systems and the best stitch for shear strength and durability. I currently use a PP 1' webbing strap and have been sewing 210D Swan brand high tensile thread (which our machine can just barely handle) in a box X stitch pattern about 1' x 1' between loops. I realize now this should be spaced 2 or 3x the width, so implementing the correction now.
We have contemplated buying a bar tacking machine to handle all of our straps we sell commercially, but after reading some other threads it sounds like that may not be necessary. Im currently asking my partner which sewing machines we use exactly (a home Juki machine), and I know that will help. We believe we are trying to do an industrial stitch with industrial thread on a machine that may not be able to handle it, which is why we are considering a tack machine.
Someone recommended this pattern: https://www.hammockforums.net/forum/...8&d=1392267873
the science behind this "W" pattern with a box seems to run parallel with the length of the strap and increases the shear strength? Is that correct?
To be honest Im a bit more lost and confused than when I started, but if I can avoid a bar tacking machine without compromising strength then I'd be one happy camper.
Thanks in advance for the help, guys and gals!
