Hey folks,
My understanding is that a good rule of thumb for "how wide should the strands be/how many strands do I need?" to plait around a given diameter is "multiply the diameter by 4.6 and that's how much width the strands should total to". For some reason I also had "multiply it by 4.0" floating around in my mind, but I can't remember if that was for something else or if I just imagined that one.
Anyway, I started doing some tests with 4-4.5 mm lace I cut from 4-5 oz single shoulder cowhide, and the numbers aren't adding up. I'm trying to plait around something that is around 3 mm in diameter with a 6 plait, but I'm still somehow coming up short with the coverage. Even at a conservative estimate of the laces being 4 mm wide, that would come out to 24 mm of coverage for 6 of them, and the equation only calls for about 13.8 mm. My coverage is really uneven, with tight plaits on one side and wide ones on the other, which I feel usually happens when there's not enough coverage.
Is there something I'm missing? Maybe the thickness of the laces is throwing off the measurements? They're about 2 mm thick each. I want to do this quick sanity check before I start planning out the rest of the whip. I don't want to get all my laces cut, tapered, and conditioned only to realize I messed up the math, you know?
Thanks!
Edit: I've done quite a few paracord whips, but I've only recently gotten into working with leather. Still getting used to the differences.
