The Flywheel. Hello Gentlemen Thanks for nice feedback. Well, now it’s time for the flywheel. It’s not a tricky part, just a few turns on the lathe. First in the lathe, I fix the surface and drilled and reamed the hole for the crankshaft.. …then then half of the outside… …after I did the same with the other side. Then drilled and threaded for the stop screw. After some polish… Not too bad. This was just a miner update but… :coffee: I’ll be back. |

Crosshead Guides. Hello Gentlemen The update continues, this time it’s the crosshead guide that need to bee done. It is therefore critical that all dimensions must be exact. I first begun with the fly cutter for a smooth surface… … then some milling and … …drilling and reaming the holes for the columns. Then milling the radios… …then drilling… …and threading for the stop screw. And now checking… … and it looks like everything is ok. Even this was just a miner update, but those things are necessary for the complete engine. I’ll be back. |

Hello Gentlemen. Thanks Ray Stilldrillin for nice komments. Oil Cups You must be wandering what I am up to, but I feel to play around a bit with the oil cups. Ones again I follow a suggestion from Mr. John R. Bentley and I am not going to use brass, instead I am using hexagon steel bar. As you can see on my skis, it’s a very simple oil cup, but it will stand out. So, first in the lathe where I marked out the length and prepare for the threading. Then I threaded the oil cup… … and some deep turns so the threading can go to the bottoms. Then some more turns on the lathe … … so that I can shape the cups. Then drilling a 1 mm hole from the bottom. After cut off I turn the cup around and drilled 4.5 mm hole. And after some clean up I feel radar pleased. And they fit well with the rest of the engine. Again no big update, but now it will take a while before I post something new, I will begin whith the cylinder block. I’ll be back |
