They have a page of MO caps?  I looked at the page for them, and it said 
that there wasnt any.  I was looking at motor run caps rated for 2350vac.
But it seems that there page is currently not working for some reason, so i 
will have to wait to check this out again.  Well if they do have MO caps, i 
will just buy those!  I suppose i will overrate my cap bank and such.
Robert H mentioned that i need a 2x to 4x rating on many of the components.
The problem there lies that the IN4007 diodes will only handle 1 amp.  The 
mot can supply upwards of 500ma.  Thats just barely giving a 2x rating, 
when he says i should have about 4x.  So what should i do?  Do i really 
need the extra amp rating, or will this suffice?   I dont even know where 
to get big HV diodes that are rated over 1A.  I guess i will give it a shot 
with the diodes i have.
