If I wanted the corners polished off, I could do that with a rasp. :scratch: Just for you, though, I added a couple more warts and gave it another try! Found out what the problem was. Had a loose crank throw. I guess the weight of the paint on the flywheels was too much for it. Fixed that thing. Now it runs just like it did in the test run before I had painted it, though somewhat quieter since it's now on a base with felt feet. Here's the vid. I started it off without the fan belt on, and when it was going, put on the belt. A funny thing will happen right after I put on the fan belt. I thought it was funny, anyway! About halfway through the vid, I set down the camera for a few seconds to put on the belt. Watch the fan. You guys go ahead and laugh. I sure did. I got that fixed, and fired it up for another go. Ran out of batteries after about 15 seconds and the camera shut down. It's long enough to see that it works well, though. Actually, it blows more air than I thought it would, and was puffing the flame on the burner around quite noticeably. Usually, the flame is pure blue, but the extra air going into the hole in the firebox was turning it yellow. You can see my hand trying to reach into one of the bottom arches to reach the air mixture on the burner, but couldn't quite see to get it and run the camera at the same time. I suppose that'll do.

Hi Dean I had a chuckle when the fan came off :) ,,, Sure is a great runner :clap: :clap: :clap:, looking forward to your next build :thumbup: Regards Rob |

Dean, that fan looks like a real winner, just a minor blip to deal with, keeping it on, but overall, that's one fine running engine, and a beauty as well. You might try ducting the air supply for the burner in separately, to reduce the fan's interference, or maybe cover the upper holes on the sides. I can't say I've ever seen a better running Stirling engine, and really look forward to building my own, so I can enjoy it as much as you seem to. Top notch job, all the way around. :jaw: mad jack |

Rob, David, and Jack, thanks much for commenting! Mad Jack, I think I'll just put a baffle in the hole. That should probably do it. I was kind of surprised that it blew that much air down into the firebox, but it sure does. I can feel a steady stream of air over the cylinder too, on the side opposite the fan. It really blows..
