The 1/4 inch copper tubing will work fine.  You could also use 1/8th 
inch refrigeration tubing for a more compact primary.  Be sure to 
make up a test winding with some scrap 12 AWG wire first to check the 
resonance point.

The cap is always larger so it doesn't resonnate with the xmfr and 
damage it.  A .005 uF cap will work great with this size xmfr.  I 
would not use a .02 unless you meant .002 uF?  Use .005 and you will 
have good success.

With a 4 inch dia. sec coil use a winding length of approx 22 inches.
