Re: [TCML] Making a neat primary

[Sfxneon@xxxxxxx]

Steve,
 
Try this first. Draw your coil full size on paper. Use a pencil on a  string, 
which wraps around a dowel or tube to create a spiral the size you want.  
(Use two pencils taped together to get the width of the tubing in one pass) Once  
you have a full size pattern, start from the inside and curve the tubing by 
hand  to match the pattern. It helps if the tubing is already in a flat coil 
and  approximately the right size. It should be very easy to inch along and 
curve the  tubing into a near perfect spiral by hand this way.

Anyone got any tips on creating a  neat primary wind? My second attempt is 
much better than my first, lousy attempt  - but it's still not very regular.

I thought about having a guide made on  a CNC mill that has an accurate 
spiral groove cut into it, feed the copper  tubing into that first, then remove it 
and install it in the coil.

I've  seen some really neat looking primary coils out there...
