[Steam-engine] Fw: Rivited boilers

[Dan Donaldson]

Lawrance,

    Are the boilers you built ASME stamped and are they all welded or are 
they partially riveted construction?  If they are ASME code boilers were the 
detail drawings stamped by the state inspector before or after fabrication? 
Or were they not stamped at all?  Did the AI (ASME Inspetor) require hold 
points during fabrication to check weld prep and fit up of parts?  I am 
trying to get as much information as possible so that I may know what to 
expect on my project.
