But, as I stated, the reason I had chosen the bondo resin is
because of the relative flaccidity of the Sonotube. I wanted to
improve the rigidity. Glyptal won't do that, right? And a few thousand
feet of magnet wire is going to be lots of weight on this little cardboard
tube with no resin.....
Well, still working on a 'real' coilform....
