Motorize it to create even smooth feed. you could pretty easily build a speed controller and using a gearhead motor you'd get enough torque at a slow feed. fuse in one pass. of course, you can also buy speed controllers pretty cheap. I think you do want reverse (in case of jams). Add a thermostat and a temp indicator. You'd have a pretty good fuser --- In Homebrew_PCBs@yahoogroups.com, "mikezcnc" <eemikez@c...> wrote: > > It's 8.5" I paid $10 for it because nobody knew what it was.
