RE: [TCML] copper tube stationary gap - was: NST rebuild good
I have a 4"dia coil I run up to 3kw. I use a static gap with 9 ( 8 actual gaps ) 1" copper pipes that are 3.25" long , and they are cooled by two muffin fans , each having a 4" fan blade. My mounting system is diffrent from others Ive seen,...it makes for max cooling & ease of cleaning. Even if you can hold the temp down on your copper pipes, they will eventualy start 'beading' and need to be lightly sanded , cleaned etc . I can simply pick up a pipe, clean it , & lay it back down & its ready to go. I can Email ya a pic if needed. Its pretty stable , spark length is good on long runns.
your coil is 6" dia ? 6"x24" is a good start,..thats the size i used on my 4" coil,..i now run the four 8" gazing ball configuration
keep sparkin' daveB
