  • Video should be working now. Was easier to build engine then to upload video.

      There is a very fine line between "hobby" and "mental illness"...

      • That is a very sweet running / looking little engine...you are making Tim VERY JEALOUS....I am just sitting here drooling...

        Videos are always annoying: Much of the electronic world is more of a challenge than the mechanical world.

        As my father told me when I considered going into electrical engineering 45 years ago: "stay with mechanical: you can see steam but cannot hardly carry around a bucket full of electrons."

        or was it 'you can carry around a bucket full of steam but cannot hardly see an electron..'?

        if he could only see what I do today (or visualize since most of it is electrons....)...

              • First video 10 PSI, about 400RPM
                Second video between 5 to 15 PSI
                Still need to adjust the valves a little better. Will do that after final assembly and then mark them.

                  • Hi Guys, gathering materials for the boiler, can you tell me the length of the 5" OD boiler shell. I am guessing 12"

                    • My boiler is 12"
