Question:
If a two-cylinder version of this engine was to be built from the published drawings, what would be the best crank configuration? Just asking.

The question still stands.

Haha that's funny.

But just so we all know, that post is not suggestions for you but rather ineffectual spam for construction contracting services in Haiphong Vietnam. A moderator should delete that post.

That is a lovely job, and it makes such a refreshing change to see, and hear, a model ic engine working under a proper load instead of just ticking over or being revved.

Hi Jeff,

Well done, runs very good with a lovely sound. What do you think about a period switchboard and some tiles on the floor?
Do you start it by hand or with the use of a power drill?
Anyway a very successful project. Heat off !

Kind regards,
Johan.

Hi Johan,
A switchboard and tile floor will be part of the my current project. It is progressing now. The Bruce-MacBeth usually starts easily with a few turns by hand. It runs on propane, which helps.

Re: Posting # 22:
Hoping some forum members will speculate, or offer opinions regarding the crankshaft configuration for a modified, two-cylinder, version. One piston up, the other down... both up....??

Thanks,
Frank

Hi Frank,
Just some random thoughts. With a 180 degree crank you would stand a better chance of balancing due to mass up, mass down. Some Triumph motorcycle engines were 360 degree cranks, both up at the same time and operated fine. It's just that more counterweight is needed. Personally if I were to build one I think I would go with the 180 crank. You will also get a different firing cadence with the two configurations.

G. Britnell-

I appreciate the input, and for the explanations regarding both crankshaft options.
