    A truely saintly woman.  There is nothing better (except for a wonder
wife) than good power tools.

    Well, the metal work will actually be fairly easy as soon as I can aford
to pay some movers to move my mill (I have it stored at my parents home at the
moment).  As far as the electronic goes, I am always willing to look at other
peoples ideas.  I have a good idea of what I am going to do, and I need to
build up some breadboards of the various components (a 1 channel mixer) and
check it for noise and power supply rejection.

    I was thinking of keeping the mixer pretty simple.  A master gain selector
switch, pan pot, output channel selector switches and a fader for each input.
I was looking at the Panasonic pots that digikey had and was thinking of
getting a set to see how good they were.
