Re: [TCML] Splicing wires - Secondary Coil

 Tom,

For wire that is 28awg or thicker, I file a wedge shape at each end to be spiced.
I don't remove any insulation other than on the wedge.  The wedge is a one
sided wedge, like a bevel....  Not a two-sided wedge.  Then I tin the wires along
the wedge. Finally I solder the wires together so the wedges overlap.  If this
is done correctly, the joint is smooth.  It's best to practice the method using
a thicker wire such as 14awg to perfect the method.  For a 28awg wire a
jeweler's file is needed to file the wedge shape, because the wire is so thin
it's a little hard to handle.  I used this method near the bottom of my TT-42
secondary coil which the wire was damaged during initial testing when the
coil was somewhat over-coupled and suffered some damage from racing sparks.

Alright folks - suppose you are in the middle of winding your secondary and the 
magnet wire snags and brakes. Or maybe you need 2000' of magnet wire and all you 
can find are 1000' spools. Or ... etc
 
Let's just suppose that you can't get a continous piece of wire for your 
secondary coil. What do you do? Can you splice magnet wire effectively and not 
hurt the electrical integrity of your coil? What are good techniques to splice 
single strand copper wire? 
 
Thanks,
Tom
