Hi, thanks, that is a much better idea, a lot quicker using gravity, KOOL!

the spacing you might use would include settings that were less than 1/4

staggered or high and low pipes for a shorter overall distance......some
glued the end of the pipes to a block of plastic, one even was made on a
flexible surface and as the tension was increased the gaps became
wider.......interesting and very simple design.  My best recommendation,
look at a lot of pipe style gaps, decide which is easy to make, and
expirement.....you own innovation might be just what your coils needs to be
happy....enjoy...Brian F.
