Hi Gary,
What's "reasonably parallel?" That's part of my problem and I am wondering if 
anyone has developed a particular technique for spacing the couplings? I have 
mine mounted on 8-32 screws and fixed with nuts so I can adjust the vertical 
height. They look like the olive on the end of a toothpick. :-)) 
The toothpicks...uh screws pass thru 1/4-inch thick acrylic with a slot cut 
into it so the screws can slide horizontally. So I have horizontal and 
vertical freedom of travel and adjustment. A nut and washer on top of the 
plastic and under the coupling
enable the whole toothpick to be locked in place. Brilliant, huh? The big 
flaw is that as soon as you tighten down on the lock nuts it changes the gap 
settings. Lucky if I can
guesstimate within +/- 5/1000ths. I cut up a Tropicana OJ jug for shims to 
help get a little more uniformity. Any suggestions---please? The sparks are 
all off of the circular face.
None are seen to come from the cylinder walls. I have been able to set the 
gap at
0.028 - 0.030. The mmc is at 0.011 uF. Not even a gap of 0.018-0.020 will 
fill a 0.022 uF mmc. 

Happy day,
