Hi Dave,
  I do not know your chargers design and even if I did I do not have 
the detailed engineering knowledge to work it out. If you are having 
good success with it Its obviously getting close if not there on 
field saturation.
Maybe the beast thats on Ebay will do what we want maybe not. Looks 
very much like it will. But just because a machines a magnet charger 
does no necessarily mean its set up and designed to do what we are 
doing. I can not honestly answer that. The machines that was at 
Triplett was not easily adaptable to our purposes. So when they went 
out I never pursued acquiring one.  I took another look at the pics 
of the charger on Ebay and its design varies from  the one near me 
thats part of an actual Weidenhoff "Magneto" Test bench. But he also 
admits to doing a good bit of repairs or modifications to it. So that 
may be throwing me off and the fact that the other one is not in 
front of me to compare sure does not help matters any. CRS disease sure sucks.
  Sorry my terminology is not technically detailed I just have a 
working understanding of the basics learned from various sources 
through time. Built some motors and magnets when I was a kid. I paid 
real close attention to high school science and absorbed all I could 
there but since then its just reading what technical mumbo jumbo I 
can made heads or tails of. Theres a point in the every day world 
where jargon starts to get in the way of understanding for the common 
fellow like me. But it really helped when I started to work for the 
motor compressor shop here in town when I escaped school. Learned a 
lot from the old timers that was still around 30 years ago. They knew 
practical theory in laymans terms not detailed engineering theory. Or 
maybe they did and I just never realized it because they could 
explain in a language I could follow along on.  Hell I just hope I 
guess right half the time. Time for some Black Velvet.      Mark
