When I used to have a "traveling job" I always brought a 1 x 12 x 36 pine building board, basic building supplies including "pen vises" for drilling holes by hand. I didn't own a razor saw back then, so any cuts in hard wood or ply wood were done with hacksaw blades or a coping saw. Everything else was done with the old #11 Xacto blade. I used a standard steam iron to apply iron on film, it worked just fine. All this was done at those tiny tables that Motel 6 provided while watching whatever was on the Motel 6 provided "Boob Tube" that evening.
