[TCML] Gaps

["Brian Foley" <ka1bbg@xxxxxxxxxxx>]

Hi, I built a so called "RQ" gap, pvc with copper tubes inside, i use a computer fan and the top of a pill bottle so all the air is in the gaps or thru the pipes. It works well on my coil. 
For those of us who have built coils and been coiling for years have found Tesla Coils are as unique as people...what works wonderful for one coil doesnt mean it will make your coil wunderful....there is no perfect size, no one size fits all...
there are many designs that built carefully work just fine, once tuned to the parts of that coil.......
this style gap seems to suit smaller coills up to several KW or a little more....If you ran and tuned your coil to a simple gap set at 1/4 inch then the spacing you might use would include settings that were less than 1/4 inch and slightly more than 1/4 inch...
Gap distance divided by the number of gaps approximately..
I found the pvc pipe difficult to drill slots so the pipes could be spaced to a certain gap distance......easily done however in a machine shop....Now there are many gaps made with pipes layed out flat, one used 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.
