Re: tesla coil part matching





Use rolled PE cap in a PVC tube filled with oil if you can.  The water caps
don't work very good and glass is a terrible dielectric.  If using bottles
you will have to make one and then measure it's capacitance.  Most local TV
repair shops have meters and could help you do this.  Any large college or
university will have research departments that have such meters and could
help you out.

Use 20-30 turns of 12 AWG scrap house wiring supported on edge slitted
pieces of cardboard to make a test primary.  After finding the correct tap
then make a nice shiny primary with copper tubing with a few extra turns for
tuning.  If you are short and have too few turns you will never get the coil
working properly and probably destroy it.
