RE: STEAM BENDING LUMBER
I need some advise on steam bending lumber.
I have seen several other people’s home shop operations in various publications and my old text books from woodworking school in the 1960’s. But here’s what I am using and I need to know if I am getting the maximum efficiency to steam bend 1″ thick lumber 3″ wide.
PROBLEM IS, I AM BREAKING ABOUT 50% OF THE STICKS I STEAM BEND AND IT’S VERY FRUSTRATING.
20 lb. propane bottle heating a 75,000 BTU stove;
2-gallon gas can (never used for gas as it was new when purchased) with a 1/2″ radiator hose connecting to a 10 foot long x 4″ daimeter ABS drain pipe w/ two 1/4″ drain holes. I usually heat a piece of wood for a solid hour before removing to clamp to a curved fixture.
IS THE RADIATOR HOSE LARGE ENOUGH DIAMETER TO EFFICIENTLY HEAT THE LUMBER?
AND, IS THE 1 HOUR PER INCH THICKNESS STILL A RULE OF THUMB?
