Yes that is about it I think, R was 5.2R as I posted a little while ago.

When its all done I will take readings again.

One thing I did think about afterwards is to place some plastic over the
coil around the transformers which I am using as weights, For the simple
fact if they fall over it will bash the windings ont he flat coil and could
easily waste hours of work.  When its all finished up I will try to take a
shot on my web cam :)
