The gentleman from Texas got me to wondering. I just tried out my acetylene regulator on a little BBQ 20# propane bottle - fit perfectly.
Is there any reason you can't use an acetylene regulator on a propane bottle? If you *can*, then is there some reason all the propane forge guys don't? They all spend $60 on Goss propane regulators! I see acetylene two-stage regulators all the time, well built, completely rebuildable forever, cheap.
