Re: Shay boiler question

Ok, its nice to know definitively what it looks like.
Now I just need to figure out how to make this one.

The section under the steam dome is just a little taller than a standard 42 ton (54" dia outter shell) with the steam feed pipe coming out of the side of the boiler under the dome.

This boiler here, While still a 42 inch boiler by spec, measuring the broadside of this class of loco, the slanted rear top sheet models are alomost 6 inches or so bigger in diameter, or at least taller, just in the spot where the steam dome is. If its a circular diameter then its almost 60" dia.

Though Im wondering if it is NOT circular under the steam dome; like maybe the boiler tube is circular, at the rear slope at the back head, then has a hump on top of it under the dome, making it oval shaped at the point it is under the steam dome.

I would appreciate any input on this boiler shaping I can get.
There are still a few of these left around in STD gauge.
