Homebrew PCBs

Well The good news is it works and it works really really well The 
toner is rock hard and fused to the board I have found that slowing 
the motro to helps as the board absorbs a lot of heat as it passes 
thru the laminator. I found that 220Deg C works well for the feed 
rate of my laminator. I am awaiting a roll of toner sensitive film to 
arrive as I believe this will stop any bleed thru problems I have 
been getting on the larger boards.
