I took a giant step over the weekend. I wound my secondary, a 6x24 with 22
AWG.
My wooden winding assembly worked well.
I cranked with my left ahnd while I wore a groove in my right thumb. And, of
course, I stopped
every so often for a coffee break and for letting the cramp in my right hand
subside.
But it went well UNTIL....

Masking tape is fine to keep those loops in place while you are winding or
going for a beer.
BUT, do not use them once you start to apply polyurethane.
This dummy forgot that poly DISSOLVES the sticky stuff on the tape.
So as I'm slopping on the polyurethane I notice that my bottom turns are
loosening!

Emergency measures...get fingers totally glopped with poly while I skootch
the windings back into place (a technical term) and hold them awhile to set.
Apply some more tape. It holds.
Then I finished the first coat and tonight I'll remove the balance of the
tape after I apply a small drop of hot glue to hold the bottom and top
leads.

That copper and the poly make a pretty golden glow. How poetic.

But a question to all, please:

How do most secure a 6 inch diameter tube to whatever is the base of the
assembly...maybe the platform beneath the primary opening. If you just let
the end sit there, what prevents it from tipping over? Then ends, of course,
are sealed with non-conductive epoxy to 6 inch diameter plexiglas disks.

Thanks to all for all the questions answered to date.
