Homebrew PCBs

HI all , I have a supply of fr-4 pieces left over when a local pc 
shop closed  mostly double side copper clad most are .045  and .062 e-
mail me with the size you need for your projects and a fair price per 
piece by square inch and i'll see what I got to fit your needs.  I 
really enjoy this groups posts and have learned a lot from you all. 
thanks and keep up the good work. I read in an australian hobby book 
that attaching  a carbon rod with a wire to the board being etched in 
CUCL H202 would speed up the process by creating an ionic situation 
like a battery. wonder if anyone has sucess with that. thanks Luther
