Either a heat-bonding/baking or varnish-binding method is highly recommended to prevent this less than optimal situation. Vance Dickason said he wound coils in college and dipped them in something starting with a 'G' when I showed him mine at MWAF a few years back. I just use polyurethane. The zipping of the coil is mainly to hold the structure together while the varnish dries. You could remove them after curing, but the polyurethane also holds the zip-ties pretty well too.

    I do normally see the solid-core coils with tape alone more often than not. I'm sure this has something to do with not dipping the steel core, but I've even dipped some upwound steel-cores and had no issues. I have also used undipped coils from distributors, but if I make them myself i make sure they are not coming apart.

    Being unhappy with some of the coils I've purchased in terms of binding, I've rezipped, removed loose ties, and even re-dipped said re-bound coils.

    I wound a few coils by hand, nothing very impressive, not so easy to do if you don't have a coil winding machine.

    Mr. Dickason probably was referring to Glyptal, a company name. All sorts of insulating coatings.

    Four or so zip ties aren't good enough? I have unwound several quality inductors and they weren't "dipped" in anything to bind them, just wrapped with good quality tape.

    If she's innocent, she has nothing to fear.

    What I do now with the project finishing and coil-dunking, I have no use for the satin or matte in these applications.
