Guilty as charged; I have more pictures to post and I'm slipping at my duties. I will try to get something up in the next day or so.

Thanks for checking on us.

Hi Guys
Here is a quick update on the Otto & Langen

Max wasn’t real fired up about hogging a flywheel from the solid so he started looking for a suitable casting. It turns out that an IHC Tom Thumb flywheel is pretty close to the right size also the number and size of the spokes is also a good match.
The flywheel casting did have a counter weight but that was machined and fettled away.


Here is the mostly finished flywheel.




Here are a couple shots of the flywheel mounted on the engine; I think it looks pretty nice!

Work has also started on the base; I will try to get some pictures posted in the next day or three.


Thanks for checking in.
Dave & Max

That flywheel is a good match, style fits right in with the rest of the engine. An incredible project!

That's a really nice looking flywheel and great pictures. I really like the depth of field you get.

Chris Jim & Dave thanks for the comments.
Wow where does the time go. I have had these pictures for a while now and just never got around to posting them.


A wood base was made from African Padauk hard wood. The fuel and exhaust piping has also been added.


The bottom of the base was milled out to accept the S&S ignition module, batteries and to make room for the head and spark plug.
At this time the engine is pretty much finished and running. I will try to get a video of it posted in the near future.

Thanks for checking in.
Dave & Max

Hi Dave, a very good solution to hide all the electronic stuff and wiring  in the wooden base.
Waiting for the video and thanks to Max for doing this nice engine.
Kind Regards
Achim

I sure do appreciate the clean work Max is doing. Every detail is crisp, clean and "right". Finishes are perfect and the 'shine' is not excessive. His work has the unmistakable look of a master...
