Welcome No_Dude. Your in the right place. Just keep reading. There are a few on the FF from up in your area. Give me a shout if your ever in the central part of the state. I can teach you all I know in a real short visit. But stay as long as you wish. I didn't build my mill, but made a lot of mods. Dennis

1MBF is 1,000 bd-ft. A board foot is 12"x12"x1" - a measure of volume. A 10' 2x6 is 10 bd-ft.Band thickness is related to the wheel diameter - the thicker bands (.045 vs. .042) will fatigue and crack going over smaller diameter (<20") wheels. Also, the wider the blade (1", 1.25", 1.5"...) the thicker the band will likely be. The wider and thicker the blade, the tighter the band must be stretched. Also, the more HP you will need. The wider the cut, the heavier the band (and higher tension) and more HP needed to keep the cut going flat.

OK. You know a cord of wood is 4' x 4' x 8' or 128 cu-ft of wood. A cubic foot of wood is 12 bd-ft so a cord is 128 x 12 or 1,536 bd-ft.

Also on your porta-mills what are the outside rails and the supports that span the inside made of size wise? Any good place to read on the relations of band thicknesses, FPM and the like?
