Here is a picture of the backhead.  
Ray I meant to mention you need to take a good picture of the spec numbers on that piece of boiler tube just for future reference.  If ever the need arised to get the paperwork for that tube piece I might be able to get ahold of it.  
For those following Rays progress it should be noted that the pieces of steel that go into boiler building are specific grades of low carbon tube and boiler plate.  Ordinary tube and plate steel are not acceptable as they can work harden and crack under the heat and stress of a fired pressure vessel.  As can be seen in the photos Rays boiler barrel is a piece of SA-106 grade seamless tube.

Tim,  I do feel a little better after seeing your boiler.  That thing is huge. I have taken some close up pics of the tube #'s. Thanks for mentioning that.   Sng42  you were close on the firebox  dimensions .  Since it is tapered the measurements change front to back.   front is 9 5/8 "wide , 8 1/2" high, rear  9 1/4 "wide 7 1/2 "high, and  grates will be  15" long.  After running the raritan  for 26 years now, and yes that is even hard for me to believe.  I have gotten used to shoveling coal almost constantly to keep that little boiler hot, and running the way people are used to seeing it run. The raritans firebox measures  4"x 6".  The last couple of years I have had the opportunity to run some very large boilered  steamers, and could not believe how easy it was to fire. I will very much enjoy that.     Ray III

Tim,
Thanks for the post. That AS-106 number is ingrained on the brain of those of us who must resort to scrounging, salvaging or begging! It may not be known to some of the younger / newer guys / gals.
 
Yes, I said gals. I've worked in nuclear power plants and other places where tig welding is commom place. Some of the finest tig hands you will ever meet are gals.
 
Thanks,
Greg B.

Thanks for the specific dimensions. I am trying to learn what proportions fire well and run clean. Some that I have looked at given complaints about steaming had tube/grate ratios less than 10%. This leaves too low a draft per unit area through the grates and too low a firebed temp, resulting in a sooty fire if even slightly overfired. One of them had 1/2" flues which would soot up if you crossed your eyes. Your design shows the benefit of many years of experience as the larger flues will tolerate soot better and the higher draft through the firebed will burn cleaner. My boiler is shorter than yours and has proportionately less tube heating area, but a larger tube cross-section, thus a strong draft. It steams well and will recover from sooting up a bit sitting in the yard. The very strong draft quickly raises firebend temps and sandblasts the flues clean once you get going. You are right about firing your Raritan frequently and that comment alone tells me you really know how to keep a thin, hot fire and clean tubes.  
 
A steam engine is a collection of unstable systems. At any given time, something is going where you don't want it. Fire is burning out, water is dropping, steam is dropping,.... In training newbies, this is perhaps the hardest point to get across. Like a flywheel, a larger system has more inertia and is easier to manage since things don't change so fast. You should really enjoy this Mike. I don't know what you expect for a drawbar, but I am guessing around 300lbs, minus friction losses. Bore/stroke and driver diameter would let me guess a little closer. Good luck finding enough cars to load it down!!

   Ray,
 
   I do think we can find the cars to put a "little" load on the engine at the BCRR when you come down for the un-meet.
 
   As far as good steaming attibutes of your boiler goes. It seems a few posters here have no idea who's shadow you and even I stood in to learn the stuff to make engines run right. We were indeed fortunate to have had the expierience of learning from J. Cassady, J. Van Sickle,  B. Schneider, plus a few more "live steam gentlemen" here in Florida.
 
   One only needs to log in to "youtube, papasmurf7597" to find your Raritan running. With a boiler that you built many years ago. I do believe that these vids should show definitively if both you or I know what we are doing with either building or re-building a boiler.

Bruce , I can't wait to load the engine down, and  take it up on the new trestle .  That will have to wait until next year unfortunately.  I had hoped to have it down there this year.   With the engine still, a ways from completion, I have decided to stay home this year.   I have made the trip for  the last 10 years,and I will certainly miss  being there.  I have not  worked on the boiler very much ,since  mid december [holidays and family time].  I did remove the firebox in early  jan and  run my seal welds  on the inside of the outside sheets.   While running the seal welds , the outside sheet on the firemans side warped .  This was a small setback. I have since  resolved that.  The next  step will be welding all of the pipe couplings on the boiler for  fittings  to attach to.   4 @ 1/8th" checkvalves, 2 @  1/2" safety valves,  1 @ 1/2" bottom front of barrel  for washout,  2 @ 1/4" blow downs,  2 @ 1/2" washout back of firebox ,  3 @ 1/8th" backhead for  sight glass & pressure gauge.  When all of that is done I will reinstall the firebox .  Ray III

   Ray,
 
   As always, beautiful workmanship. But after knowing you all of these many years, I would expect nothing less.  
 
   I can't hardly wait for your next visit to the BCRR with that "Mike".  
 
   Safe journey on your upcomeing adventure,
 
   Bruce

Hello everybody,  the welder has been collecting dust for the last  7 weeks.  I have been out of town, borrowed out to another portion of the railroad .  There was a shortage of engineers ,and I was asked  if I would be interested .  This was  an opp I could not pass up.   A bonus of the trip , was the  railroad  museum  in Duluth MN. A wonderful collection of equipment.  Everything from a 4-4-0 to a  DM&IR m-4 yellowstone  2-8-8-4.  The icing on the cake is the  1 1/2 " scale  M-4.  I have a ton of pics to show you.  The  DM&IR used these  engines until 1960.  They saved  3 of the 18 engines.  The  one in the  museum was rebuilt by the  DM&IR & retired DM&IR employees, then donated to the  museum.  It runs  twice an hour with electric motors.  The other  2 engines are  within 30 miles of each other. One in Proctor MN, and one  in Two Harbors MN.  Both out side  but  taken care of.  I am ready to get  back into the boiler  project,  hope to start in the  next day or so.  RAY III

This is the  #225  in Proctor MN.  This engine sits less than a mile from the  yard  it  used to operate out of.  these  engines weighed over 1 million lbs with tender. They  were rated at  6000 drawbar  h.p.  They were often seen pulling  180  loaded 24ft ore cars , 70 and 50 ton cars were the  norm. the trains weighed as much as 18,000 tons.  It takes  3  new diesels to do that today.

the small hoppers in front of the  sd-40 are the same cars that the m-4 pulled 48 years ago.

Welcome back, Ray, you've been missed. I knew you'd fall in love at the museum. I spent many weekends there, back in the 70s. Northern Minnesota, back then, was railroad heaven. Every little burg had a display of some sort.

thanks Greg.  Yes  that is a very neat  area.   railroad and  maritime .   this next pic  shows  the water glass and the  neat thing  in this pic is the plate to the right of the glass. its hard to read but the  3 lines  are for correct water  levels on diff grades. the bottom line is for level track , the  middle line is for  1% grades  and the top line for  2% grades.  These engines were  on 2% grades every day.   Trains coming down the hill from the iron range  experience  1.7 - 2 % grades.  Let me tell you  , when you  are coming down a 2% grade  with 13,000 tons ,  you better have your game face on.    It was very  challenging in a good way.    Ray III

Nice Pics.  One question,  WHERE is your HOGGER HAT.  You can't run a steamer without your Kromer.

here is the 1 1/2 " scale version of the  DM&IR #225. Itwas built  by Ralph W Andres. Started in 1963 and finished in 1994. It has been on display  at the museum since  1998.  A friend of mine was used for size comparison.    Ray III
