That darn weight that fits up into the sand dome and down into the notch in the boiler weight seems to be a large amount of the problem with removing the shell. Why not cut that weight in two, with the upper part stuck into the sand dome, and the lower part resting in the notch in the boiler weight? That way, shell removal and replacement in the future would be easier. Or, am I missing something? I have 2 that I have to get around to "doing" for various reasons (like turning one into a B&O T-3).
