I get the impression there is always something extra to do with these engines Olli, nearly there though. :thumbup: Nick |

Well, the fat lady just started singing (but sheīs not finished yet). She sings so loud that the table shakes (the engine/flywheel is still largely unbalanced). Some more pics. This shows the shorter power stroke. Changes since yesterday: Pushed the Oilite bushings out, and substituted one of them with a Teflon bushing. Changed the (=made a new) power piston connecting rod. The old one might have worked in a well-balanced engine, but it was too heavy (I told you...). Shortened the power stroke, drilled and tapped another hole in the crank disk. The displacer volume is now so much less than intended that it cannot push the power piston all the way through the power stroke. Thereīs still a mismatch, but at least it runs, sort of. I will make another much longer displacer piston, and cut the other test tube to size. Maybe also lengthen the displ. stroke. And make another spirit lamp. I temporarily pulled the wick out from this lamp, so I could get a bigger flame for testing (and filming). But this engine needs a lot more heat than the smaller one. And of course will consume more alco, so the itsy bitsy burner is a bit ridiculous. The engine so far makes lots of noise, that also needs some tlc. The other one is very silent. The flywheel(s) must be balanced. As it is, it will promptly walk off the table. And general blinging might be of benefit.. My son will go to London next week, and he promised to get me a cigar in a one inch tube. I just need the tube, but I will smoke that cigar also :D Always nice when a new engine behaves. :beer: Thanks for watching, more when thereīs some significant changes. :wave: |

She runs :bow: A great looking engine too! Ive been thinking of building a stirling engine and this thread has only helped to further convince me! |
