Sub'd, y'all.
DHC is selling their Nucleotide 24 ga. OCC copper/clear teflon for $1.99. I'm thinking about braiding that stuff nekid. What's the rule of thumb for estimating how much extra length you need when you do a four wire braid? I'm shooting for a 10' finished length.
Thx
Depends on the AWG and how tight/loose you braid. I tend to leave myself about 6 inches for every 5 feet to compensate for the braiding and mistakes. Though that is always more than I need.
I do a "natural" feeling braid. I Try to go with how it feels while doing my best to avoid tightening or loosening too much. Usually you can feel when it is doing one or another followed by seeing it after a couple of passes.
So for 10 feet I would recommend between 6 inches and a foot depending on how confident you feel. . Should be plenty.
Edit: I should give a specific example. Just did a 5 foot cable with 26awg. Lost about 1.5inches off the length. But again, YMMV.
