Hi All
Well the McOnie is finished and running. It's taken about four months, the reject pile
is not to bad. This model has some interesting machining hurdles, but with some help
from Ramon and photos I was able to download I think the finished engine is quite
interesting.
The valve events are unique in that the port just cracks after TDC then opens rapidly
to full port opening then closes just as fast before BDC, I can only assume it has something
to do with the crosshead design.
Photo 1 shows the engine at speed.
Photo 2 is the governor end.
Photo 3 is the cylinder end.
Photo 4 is a side view.
Should anyone be contemplating building one just drop me a line and I will see what
I can do re photos etc.
I will be going on a Holiday shortly so will have some time to think about the next project.
Cheers All
Thanks for the nice comments as the build progressed.
Mike.
