The picture below is of my Clishay with the new boiler setting in place, just to get an idea of how things will look.; Setting on a digital bathroom scale, this boiler weights 42 pounds.
This pic was put in just the for the fun of it. (from below the engine looking up through the firebox and through the boiler.)
John kept having to coax his tubes in place. Had I not drilled and reamed all four tube sheets at the same time, I would have thought I might have grabbed an undersized reamer for his sheets.
It tooks us a while to conclude that his tighter tubes was because he got his tubes at his local Home Depot and I got mine near me, which was two different stores. We could only figure that two different suppliers had provided two different size tubes. Now we are only talking about .001 - .002. John's tubes measured .626 and mine measured .624 and the holes were reamed with an on size .625 reamer, which gave a .6265 hole. That's really why John is standing like that....
He almost get that one stuck and had to use a wire wheel to clean up an end. He had to do that to almost everyone of his tubes.
Eventhough he does not look too thrilled about cutting out the 8 pieces for the "riser wings", I kept telling Justin that he was really having fun. I told him that I took this picture so I could later bring it out and show him just how much fun he was really having. Besides, the apprentice has to start somewhere.
The final result of today's efforts. They're flared. Next, they get swedged. Now, the boiler weights 51 pounds. That translates into 6.25 pounds more tractive force per wheel. Dry weight.
