Really Cheap Secondary Xfrmr Tube



Goto Office Depot.  They have <=3" Diameter
and 33" long tubes to mail Posters etc. in.
These are very strong.  I tried to crush one with 
my hands and i couldn't, i couldn't even bend it!!
I tried hard too.  You can't build a big coil with it.
But for a 4 dollar tube, you can't beat it, especially
after a few good thick coats of polyurathane.
