Re: [TCML] New Coil

Miles,

The recommended minimum proximity in Javatc is calculating the distance 
as the "nearest points" as noted in the help file. If Javatc tells you 
1.5" as the minimum proximity, then it's looking for a primary diameter 
that meets this distance. Javatc does not suggest a primary diameter in 
any of it's outputs.

Take care,
Bart

Using the javatc tool it suggests my primary inner diameter to be only 1.5" greater than the secondary form (a difference of .75" radius), and to obtain .14k coupling the lower end of the secondary is .5" below the primary.  I worry when the primary and secondary is that close; should I?
