Guys... I really appreciate the encouragement and the kind words. The last post ended with a couple of teases, like the flywheel blank and tank test placement. The flywheel has come a ways since then. I modified the 5 spoke instructions given in one of the Duclos articles to make it a 6 spoke version. This took a little rejiggering of hole sizes and placements, as well as the radii of the spoke curves, but nothing brain stretching about it. The project kept getting delayed by family matters, including an 8 hour middle of the night round trip drive to retrieve my son and his broken arm from a wilderness camp in the Great Smokey Mountains. Nicholas is doing fine and seems to ignore the pain as if it were nothing. I finally got back on course late yesterday and made up for some lost time. The photos below show the flywheel just after it was mounted for testing the wedge lock which secures it to the shaft. This is basically a cone that has been split at 90° so the 2-56 screws can force it to squeeze the crank shaft. Quite an effective way to mount a flywheel. All the hand filing work is now done, but the flywheel will see quite a bit of hand polishing yet, before the job is done. I think I'm on the right track with the engine, but will be visiting a local model IC engine guy tomorrow, just to let him critique the project so far. Not having messed with IC engines, I'd like to be sure I'm on track for a runner. For those who are curious about making curved spoked flywheels, I posted a write up on the HMEM board back in October on the subject. You can check it out at http://www.homemodelenginemachinist.com/index.php?topic=3169.0 Ralph... After 20 years of interest in steam engines, the governor was actually pretty straight forward. The only tricky part was making it all fit in the limited space that was available. That required a bit of give and take where one robs Peter to pay Paul. By going with round rods and smaller diameters, along with slightly over sized balls, I managed to gain just enough space to sneak past the limitations. I got to smoke test it a bit tonight after securing the flywheel. IT WORKS!!!!!!!! although the spring tension might require some trial and error experimentation. Steve |

Lovely job Steve that flywheel is a work of art :thumbup: Stew |

You are a real rotten bu**er Steve. Every turn you take, you come up with another jaw dropping feature :jaw: :jaw: I suppose for your final trick you will have the engine running 1" above the bench and rotating very slowly, with no visible means of support. You are giving us a real goal to aim for. John |
