[Steam-engine] Dan's Boiler

[Dan Donaldson]

Andy,

    I am only doing some of the work myself.  I have bought all of the steel 
(with matching mill certificates) through the company I work for.  All of 
the parts are being or have been cut on our CNC burning machine.  I am 
almost done drilling the rivet and stay-bolt holes using two magnetic core 
drills at the same time (that way a 5/8" or 3/4" hole is drilled every 30 
seconds).  Soon I will be using our plate roll and brake press to form the 
sheets except for the backhead and the throat sheet.  The backhead and the 
throat sheet will be heat formed using a 2 3/4" thick piece of steel that is 
cut the proper shape with rounded edges.  After all of the parts are formed 
they will be fit together with temporary bolts and I will take the boiler to 
Ohio were a certified ASME boiler shop with an "S" stamp will weld the 
firebox and  longitudinal seams on the barrel and steam dome.  Then it will 
be stress relieved prior to stay-bolt and rivet installation.
