Homebrew PCBs

Thanks to all that helped with this.

What i did was get an old cloths iron and took out the thermostat and bolted
it to the
roller casing (same place where a fixed 120c thermostat was mounted) wired
it up and
set it to about 180c (my toner is HP black).

Made a layout onto some inkjet colour paper, scrubbed some pcb with brillo
pad, cleaned
with some acetone, run the board through the laminator 5 times, let the
board cool down
and then soak in warm soapy water(some of the paper stuck between tracks)
but rubbing
with my thumb soon removed it!, and all the tracks stayed on, etched the
board and it is perfect !!

So i'am a very happy chap
But i still think that i would like to use a temp control circuit, but then
i would have to fit a
transformer and psu for the temp control inside the laminator case.

Thanks again to all

Howard
PS. anyone help with a good etchant ?
