Nice project!
I don`t fully understand how your crank is being mounted, can you explain a bit the design?

So simple and so clever! :bow:
Thanks for the pics, they explain everything!
 
Hi Tony,

Nice work on the engine, like that crank :bow:

Question, how did you make the seats for the crank bearings in the block? In the lathe with a boringbar, your mill, other? I have been thinking quite some time how to achieve a nice round boring in a relative long block.....

Keep the pics coming!!

Best regards Jeroen

Very nice work, Tony. I appreciate the clear descriptions of the operations in your thread.

Hi Tony,

Thanks for the clear explanation, it helps a lot! Nice tip of sacrificing an old tool bit holder and put that in the bar. I will keep this in mind when I will build my first multiple cylinder engine in some time.

I will be following along your build.

Best regards Jeroen
 

Great looking work as usual Tony!

Keep it up.
 
Great looking engine! What's the bore and stroke?

Chuck
 
Tony, your engine is looking great! :bow:
 
Hi Tony,

Very cool, When we have more news?

Take care,

Alexandre
