a Multilayer Coil
following figures show a method(1) of forming a multilayer
coil which produces a neat winding. The most complicated step is
producing the spiral as it requires tacking with adhesive at regular
intervals. The most suitable adhesive for rapid winding is cyanoacrylate
(superglue) and obvious care should be taken to avoid sticking fingers
to things. Cyanoacrylate may not take well to some surfaces so experiment
before attempting to wind your prototype.
cyanoacrylate won't work then the next alternative is to use a fast
setting epoxy. You will probably need to hold the turns of the spiral
with some sort of grip to allow the epoxy to set, unless you wish
to apply finger pressure for the duration of the curing time (not
recommended!). Clothes pegs may work well for this.
the spiral has been formed the remaining layers can be wound back
and forth to complete the coil.
