Thank you Kay, good to hear from you.
I sent a private email just last week and have not heard back from his wife.
The last I heard was that he was still hospitalized and fighting whatever
the problem was (I did not pry). I believe it to be serious, but yet
unidentified to me.
Thank you again for the URL. Back in 1998 he had suggested a glass type PCB
and that is where I fell into trouble (if I remember correctly.)
Regards,
Jerry

By the way, has anybody heard how Chris is doing? I miss hearing from him
on this net.

Jerry,
I have built coil forms using the design of Chris Chapman. I use .062"
circuit board material without the copper layer. I cut out the shapes with a
saw and use a Dremel tool to cut slots as needed and use epoxy to bond it
all together.

Subject: A Sticky Question
In years past, I had difficulties in finding a "manual" coil winder and
ended up with an old fashioned had drill. (As you know, you have to search
using the correct words or your mouth pursed just right to be successful.)
Anyway, that hand drill is what I ended up with. The EBay choices shown
by Barry are interesting. Thanks, Barry.
Never-the-less, in past, I had more trouble finding proper shaped
ready-made spools or bobbins to wind a coil. And, if I tried to construct a
rectangular shaped form, I had trouble getting the sandwiched parts to stick
together! I suppose that I did not have the correct adhesive. I tried
several without satisfaction.
If anyone knows the secret to building a rectangular form, materials &
glue, I'd appreciate knowing it.
Regards,
Jerry
