I'm still here, just haven't had much to say. I got a new laser printer
(HP 3600n) that doesn't seem to stick as well as the 2550n at the same
temperature. I'll probably have to re-test its toner - I got the toner
off eBay, might not be HP. I was thinking about doing some tests with a
transparency - temperature, number of passes, see if I can find the
temperatures for plasticity and melting. At least you can see through
transparencies :-)

Overall, I've been sticking with UV film instead. More steps, but a LOT
more reliable.

Oh - I found out how to put 1/16" PCB through a 1/32" laminator
reliably. Tape it to a sheet of paper. Once the paper is pulled into
the laminator, the PCB is gently pulled in along with it. I laminate my
UV films this way.

Also, I'm very happy with using 28 gauge brass wire in a 13.5 mil hole
for vias. Brass is stiff enough to not bend, and friction holds it in
place while you solder.

Also, the temperature control hack for the laminator was WORTH IT!! :-)
