==========

I need to construct a 35uH air inductor using .250 copper tubing. D
is around 5"; L = 10 inches. I can play with the dia & L a bit and
still be in the Q ballpark I desire.

Does anyone have a jig or technique they use to make such a coil
while maintaining the turn spacing and not kinking the tubing? It
needs to be "pretty" because of where it will be located :-)

Thanks
