Having researched pickups I now have some wire (1500 metres of 40 AWG enamelled copper wire) a half built machine for winding, which incorporates a drill, some wooden bits and some badly made bobbins to wind it onto and some super-duper super strong rare earth magnets.  Just waiting for the glue to set and for the ready made bobbins to arrive in the post (yes I cheated).  I am building the winder using the age old principle of glueing bits of wood together.
