RE: Gap spacing

What I'd like to do in a perfect word is build a gap,
with as many elements as practible, that would
technically be to wide to be safe, but be able to
adjust it down by shorting out one or more gaps.

Something like 7 elements at .05 each for a total of
.3"?  I could short two elements out for a .25 gap, or
more if necessary.

I'm hoping to be able to copy what someone else has
been sucessful at (because of sheer lazyness :-)
