Re: [TCML] Ballastwith adjustable Core

Ed,

_Florist-wire_ is well suited for good quality cores. Here in 
Europe/Switzerland the soft iron wires can be obtained from florist shop 
auxiliary means distributors for little money. They are in the form of 
bundles of straight wire (diameter 0.5mm, length up to 50cm), colored in 
green. The color is a sufficant insulation for the purpose of avoiding eddy 
currents, and there is no need to straigthen and to cut the wires: all one 
has to do, is to form a bundle of them!

We have made cores for our induction coils out of them:
