Re: Coil Winding Advice
Welcome to the group, and thanks for your interest in the coil winding technique used here in the PL-310 loopstick experimentation.
In answer to your question about the type of tape used to hold the Litz wire turns in place, I use Johnson & Johnson waterproof 2" wide tape, as pictured in the photo below.
This tape is wide enough to cut a piece slightly longer than the length of the planned coil, then wrap in an overlapping pattern on a half inch diameter ferrite bar, with the adhesive side out. In the photo above, this tape was used as the form for construction of an E100 Slider coil, with a half inch router bit shank used as a temporary base (assisted by a thin strip of a plastic credit card, to ensure that the coil was not wound too tightly). After winding, the strip of credit card was pulled out, providing a Slider coil that was "not too loose, but not too tight."
This waterproofing tape is excellent for holding the coil turns on experimental loopsticks, and was purchased from http://www.medicalsupply.com about 2 years ago, when I was able to get a lifetime supply. If you have trouble tracking it down, let me know, and I may be able to send you a small supply to meet your needs.
