I have one of the original GB laminators mentioned in Ultrakeet's
(PodeCoet?) hack article. I replaced the temp switch with one for
300-plus (330? -- I forget) degrees F. I always use 10 passes.
If you do the temperature switch hack, watch closely when you do your
first warm-up and first board(s). The plastic top of the laminator
gets so hot it will deform. I decided to cut off the ends (they hold
the switch and LEDs and cover the motor and drive gears) and ditch
the middle 10 inches or so..
The small boards, as mentioned, can be problematic due to their small
size relative to the roller width. To insure even pressure across the
board, run them at the edge of the rollers and put a second blank, or
scrap board (that you're not processing) next to it, "inboard" of it.
This will even out the pressure on the target board.
Never leave the laminator on unattended. I always consider it a fire
hazard and make sure I'm around when it's warming up and that I turn
it off before leaving.
Good luck.
Cheers,
Dave
