Hi,

Make sure your strike rail has a goodly gap in it, so it doesn't form a
complete ring. I would try salt water caps, very durable and perform just
fine. Search for "geek group bucket cap". I didn't do the math, but you may
not have enough primary turns. There are several TC calculators out there, a
couple of them web based.
