To all interested I have noticed over the last few days that a few of us have problems with tender gas tanks freezing.
Another alternative is to place a 2nd small gas tank near the boiler, connect the valve to the burner instead of the tender tank. Join the tender tank to the new small tank with a one way valve in the line to prevent gas flowing back to the tender. You may just have to crack the gas regulating valve by filling. Now think of adding a servo or wheel driven water pump. The new problem will be steam oil. (maybe an oil pump driven by the motion? (valve gear). regards Bert. ------------------------- Bert & Edmunda [EMAIL PROTECTED]
