Homebrew PCBs

What is the largest size of board you did that way? I challenge you 
that a 6"x9" board will not laminate image correctly. I never had a 
single problem laminating small boards but it takes some tricky 
ironing to make a large board and I have ALMOST 100%. That ALMOST 
might be or might not be important, depending on the location of hte 
misfit. What you have there is a steady temperature and the pressure, 
but the pressure has to be of certain value; too high and the tracks 
are flattened. Too low and they won't transfer. Bu different parts of 
board require different(-ly applied) pressure, at least that's what 
find out. I am sceptical about your contraption until you provide 
your comments. Mike
