RE: [TCML] Ballastwith adjustable Core

["Rich Schmuke" <rdj@xxxxxxxxxxxx>]

Being a old farm boy at heart I used bailing wire and wrapped it in wire to
keep it together. It is around a piece of threaded stock , I cut the inner
flange out of a roll of 12ga , this gives about a 1 3/4 hole to fill with
steel wire , the threaded stock is hung by a wing nut through the ply wood
cover and provides adjustment. Simple and cheap.

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:

    Thanks - excellent suggestion and one I'd never have considered.
