Thank you everyone for all your input.  I should have joined the list a long
time ago :) lots of very helpful info.  I think I will get the 12 x
942C20P1K from mouser.com tomorrow.  Everywhere else I called had a minimum
order amount that was over $100.  Mouser has them for $4.28 each which will
be around $51 + shipping.

Thank you for the pointer about using 28 AWG for the secondary coil.  I
don't remember how I came up with 16.  This will save me a few dollars too
as it's sold by weight and this won't cost as much.  If anyone recommends a
site to purchase wire I'm all ears :)  Oh and is 1000(ish) turns the
standard for beginners like me?  I have 4" diameter PVC pipe.   I see lots
of formula on the internet but they require you know the inductance of your
primary and the frequency of it too.  I don't have an ossilliscope.

I'll see if I can get a few pictures of what I have made up so far posted on
the internet later tonight so you guys can take a look.

Thanks
Malcolm
