mmc question.... still working on first light.

mmc stats:
 8 strings    
3 caps per string
6.5kvdc. per cap
.015mfd +-10%  per cap

i mounted the caps on a 3/4" piece of wood  is this a bad idea???  i have 
recently read that wood isn't a very good insulator at high voltages.   i 
have yet to get first light out of my coil and this seems to be the problem.  
the reason that i am suspecting the mmc is because i tried to charge it the 
other day with a bank of 3 mot's and i had no luck at all.   i hooked the 
mot's secondaries in series across the mmc and charged it for a few seconds 
then  tried to short it out and nothing happened.  any ideas as to what might 
be going on???    
coil sats...

6" secondary  
22ga wire 
23" of wraps on the secondary
8 turn primary
1  1/2" between turns (aprox)
3 mot's in series  
assuming 2500v per mot. 
 i don't have a meter capable of testing over 1000v ac 
i have tried using a 4th mot with the secondary winding unconnected (not 
shorted) as current limiting (placed in series with input power from the wall 
socket) but i was unable to get any spark (maybe 1 mm at most)   should i 
have placed the current limiting mot in series with the OUTPUT   of the 3 
mot's ??   should i have the secondary windings on this mot shorted? 
  terry was helping me with all these problems a few weeks ago and i jsut got 
around to some more experimentation (with no luck)    any info would be 
greatly appreciated
