Really great engine. Everything looks so well detailed. Thank you for sharing.

I clicked the link from a friends computer and it opened promptly. There is also a download button.

Has anyone downloaded or looked at the Fusion 360 files?

One undocumented change is in the head. I bored shallow pockets to install hardened valve seats (press fit) with a steeper seat angle than shown in the model. Valves were lapped in with 600 grit Clover Compound. Extra tapped holes were added in the base for mounting. Oil ports were added to the...

Here is a downloadable link. https://a360.co/2rA0apm There have been a few undocumented changes along the way. Joints between the gears and cam were never established( It was not working for me nor is it necessary) Not sure how long I will keep this available. If you have interest , get it now.

Thanks for the compliments. I am really glad it has turned out well. I am still working on mounting, fuel tank, usb charger and lights. I started using a vaporizer style fuel tank. It has stabilized the running, but lacks instantaneous demand for changing load conditions. I still may make the...

I made a builders plate.

It is starting to look pretty neat. I built a PM Research generator and mounted it with a flat belt drive. I really like the green with the bronze.

Here it is in color.

I'm not sure there is even a million people building model engines. LOL One thing for sure, the Chinese have made a million copies due to the free nature of the design. They are all over Ebay for about 300 bucks. It has been a great learning step for me. I am eager to try my hand with more...

Next Video. The little piece of shop towel is a temporary choke. I am not having very good luck with the carburetor. I am going to give the Jerry Howell carburetor a try.

Had some issues getting a video uploaded.

I have had a number of minor setbacks along the way, but I finally got it to run. Between valve seating, carburetor issues, and timing problems it took a while to narrow in to get it going. There is still a lot of details and mounting to take care.

Hello, Thanks for interacting with me. LOL Iv'e been waiting for questions. I did turn the crank from solid on a manual lathe. It was turned between centers. I started with a bar of 4140 pre-hard. Cutting it close to length, then squared the ends and brought the length to size in a mill. I...

Thanks. I want to reach museum quality , but i fear i am very far away. Dream a little dream.

Hello Everyone, Finally I am getting around to posting an update. I am slowly making progress on this build. The weight arms, weights, and bracket are mounted to the flywheel. Key ways have been cut in the crankshaft, gear and flywheels. The valve rocker support is finished. The valves, guides...

Hello Everyone, It has been a while since my last post. I have had some opportunity to work on this project over the holidays. Here are some photos of what I’ve been up to. Thanks

Hello, I have an old Atlas Clausing 5904 lathe. It works well, for the most part, but I have had a hard time finding some items for it. Particularly a collet closer. The lathe has a 4.5 Morse taper in the spindle nose. I have seen pictures of a 5C adapter for this taper, but haven't been able...

Hello , Back at it a little this weekend and tonight. I made the sides and bearing caps. None of which have been drilled. Good Night
