I am in the process of sewing up my first gathered end hammock.
I'm 1840mm tall and mass 120 kilos, I'll make an assumption that my sleeping gear and ancillaries won't mass more than 10 kilos.
I'm wondering what thread to sew with and what safety factor I should sew to?
I was planning on using Ipcafil180 which sews very well but only has a static strength of 840 grams, I also have Rasant but that isn't as strong, I have Guterman upholstery thread to but that won't work in my Singer 201.
I've pinned up with a 25mm triple roll edge and I have pinned in 200mm of 75kg polyester twill tape at the end of each side seam.
If I assume a safety factor of 3 and sew using enough stitches to hold 400kg at the ends will the M-180 thread be strong enough?
Or should I oversew the ends where the twill tape is with something stronger such as M-60 bonded nylon?
I normally sew rucksacks and pulk harness and I'm not used to dealing with LW fabrics; my sleeping bags are not pretty to look at.
If it matters the fabric is cheap 30GSM nylon bought cheap as military surplus and was used in the Australian army windshirts, quite durable but a sleazy weave
