I added a second cds as you recommened and did some VERY preliminary testing and it looks like you are right.

I didn't get to do much other than add the 90 degree cds. I built a new power supply and did a major overhaul to the generator today. Made some smashing differences. I'll try to write this up and either post it to the list or put it up on my web site. Tomorrow, if anything is open, I'll look for flat black paint and make up shields for the cds.
