For those of us that haven't acquired a nice Morris coil winder yet.

Makita variable speed drill, a cam and a pulse counter and an arbor.

This is a late 30's GE radio antenna coil. Apparently it had been
hit by lightning somewhere back in the distant past. The shortwave
section was ok, but the broadcast band section wash charcoal.

ROughly 250 turns so wound a bit more and will trim back as needed
to make it resonate with the tuning cap.

Here's my version.
First photo is a bunch of little 25mH chokes I needed for a project.
I've since started using the plastic sewing machine bobbins for chokes
like this. Second photo shows a couple of them in place.

The next two photos are an IF xfmr I made for a homebrew rig. This was
slow going and the set required THREE of them. I think they were 300+
turns of #30.

Ooooher pretty.

Where's your turns counter? ;-)

Almost, but not quite enough crap on the bench behind the winder :-)
Looks like a winner to me.
