Bill,

A clip can be made with a fuse clip, or two of them.  Or you can
bend some pieces of brass to make a clip, etc.  It does not have
to be super strong or heavy.  In many cases 1/4" copper tubing
is not really needed for a primary if the coil is small.  Again, if
the coil is small, you can use # 12 or #10 stranded wire for the
connections to the tank, etc.  For a larger coil, thicker wire should be
used, such as # 6 or #8.
