Below is the handiwork of John Gaertner of BlueSwallow Aircraft in Keswick, Va., for steaming airframe wood. Set up with a propane burner feeding a small "camp stove" (left) and tank (left below), an unused paint can and sealed lid for boiling the water, a collector tube and funnel as water inlet (above) and a drip collector at the lower end of the tube (not in place here).
Steam line feeds steam both to upper and lower areas of steam chamber via the ~ 1" pipe running parallel to the steam chamber.
Steam chamber and feed lines are insulated. Chamber rests at an angle on two lumber feed stands to allow condensate to flow down and back, and drip is manually collected and fed back into the funnel.
A digital timer is affixed to any nearby appliance.
"Cork" at upper end retains steam.
Works well.
