I built a Weber Tribander a few years ago (old-school "SA612A Sandwich") and the anxiety with toroid winding was completely absent because the wire supplied had insulation that burned cleanly off with a touch of molten solder. No doubt Hans has a lifetime supply of the currently supplied magnet wire, but individual QCX builders could substitute for it. Sorry, I can't recall the trade name for that type of insulationtoggle quoted messageShow quoted text

When it comes to T1 I made an effort to start by sanding the varnish off the leads. Then I heated each lead to burn off anything I might have missed. So far I'm 2 for 2 with positive results. I plan on doing that with my 30m version as well.
The piece of sandpaper I use is smaller than a postage stamp. It is just large enough where I can fold it over then pass the wire through it. I do this several times until I see the copper lead becomes dull in appearance. At this point I'm quite confident that most if not all of the varnish has been removed. The heating the lead makes it about 100%
