Hi Everyone,

At the moment I am just about to rebuild my secondary on my solid state
coil. The secondary I have at the moment is a plastic rubbish bin wound
with 0.25mm enamel wire. It has given great service (I get arcs about 12
inches long out of it) but I am now starting to get arcs coming out of the
side of the coil (caused by not always being in tune - this semiconductor
coil is very sensitive to the environment it is in- I can stop it from
arcing by simply moving my hand to a different position). These arcs have
caused a bit of carbonisation.

Anyway, last time I wound the secondary it took me about a week to wind the
kilometre or so of fine wire onto the bucket. This time I would like to
automate the process. Anybody have any ideas about how I could do this? I
can get access to a lathe but I dont really know how to set it up to wind
the coil - any advice? Has anybody out there built an automated coil
winding machine?

Best Regards,
