Re: Above is just for ASME cert

Mik,
Well damn.
I had some spare sheet metal laying around and thought I could use a sledgehammer to form it, a little brazing rod, and make it into a new boiler for the Cab-Forward at CSRM. Should be good for 300psi!
Probably still can, nobody checks that ASMI stuff anyway.
Then we can drive the big'ol thing through densely populated areas! :-D
And why would I waste time and money on a steam boat when I'm thinking about a new boiler for the worlds oldest Heisler?

Earl,
Thank you for your response.

I guess my problem is I'm not up on current engineering costs.
That and I'm used to the live steam hobby where someone with brains can do all the leg work himself and then hire a certified welder to finish the job, and still walk away with ASME certification for not all that much money.
With CNC laser cutters, CAD computer systems and all the design data accumulated over the past couple hundred years of boiler building, one would think that boilers should be easy and relatively low cost. Modern steel is very consistent in makeup, and it all has a known modulous elasticity, expansion and contraction at a given temperature is common knowledge, stay bolts are a given factor of pressure vs. surface area.
It just doesn't seem like it should cost a fortune. :-(
But what do I konw I'm just a mechanical CAD Design-Draftsman who designs minature steam locomotives and does design studies of the full-size stuff as a hobby. :-/
