Hi, I’m building a 5 in loco, and I am at the stage of putting the boiler into the frames. I see from the drawings that the rear of the fire box end is supported with expansion mounts. But what is not clear to me is whether the boiler is sitting with the use of gravity or whether the fire box end is actually held down and able to expand and contract. Can some one help me with this please.
Thanks
Garry
