The inside turn was permently connected.  Then I used an aligator clamp
for 
the outside turn connection.

I would move the aligator clamp in and out from turn to turn.  If a coil 
tapped good from turn 12 to 14 for example, I would move the tap many
times 
usually 1/8 turn at a time to find the best location for the tap.

Yes.  Thats right.  Couldn't squeeze 3/8" tubing as small as 1/4" tubing
and 
keep the turn to turn spacing the same.
