Helena Montana Temple

01 — The railing

Thin, straight, and nowhere to hide

The baptistry railing is built from thin, straight-line infill sections. There is no curve to absorb a variation and no heavy section to stiffen out a twist. Every line in the assembly is either parallel to the next one or it is obviously not.

Thin aluminum also moves when you weld it. Heat goes in, the section pulls, and a run that measured right on the table reads wrong on the floor. Controlling that is sequencing and fixturing, not skill at the torch — the weld is the easy part.

It sits in a finished room, at hand height, in a building people walk through slowly and look at closely — and we installed it ourselves, so there was nobody else to hand the fit-up to. That is the standard the package had to meet.

03 — The cupola

Too big to ship in one piece,
so we welded it as two

The cupola was the other first. It is large, it is a finished exterior surface, and it had to arrive in Helena undamaged after six hours of highway.

So it was built as two welded assemblies rather than one. The entire base is a single weldment. The finial and spire section above it is a second, fabricated and welded complete in its own right. The two bolt together at one joint.

That split is what made it transportable, and it is also where the risk went. Every tolerance that mattered stayed inside a weldment we controlled, rather than being handed to a field fit-up. The cupola was supply only — somebody else set it up there, working from what we sent — and the only connection they had to make was the one we designed for them.

It also meant building a custom shipping frame before it could leave: a one-use structure, made specifically so a finished painted surface would not be the thing taking the load.

Nobody writes a line item for the frame. You build it anyway, because the alternative is explaining a scratched cupola in Montana.
