What sort of track width were you able to get down to? Did you have to use a lot
 of preasure with the iron to get the toner to stick? I'm interested in using th
is method but I've tried one brand of paper with very poor results

re you print the board to their transfer film and iron the film onto the surface
 of the PC board using an ordinary household iron (if your wife won't let you us
e 'her' iron you can buy one at the local thrift store for about $5). The result
 is 2 layers of resist. The film layer and the toner layer. The combination prov
ides a very high degree of resist which will work very well with fine traces and
 small holes. The hardest part of the whole process is cleaning the toner off th
e board after it has been etched (which confirms the integrity of the toner as a
n etchant resist).
