Just finished my latest engine, my first what you might call freelance design. 13mm bore and stroke
Two reasons for making this engine.
1. I really liked the external shape of the “Whitney engine”.
2. I have a large stock of aluminium alloy sections which could be used to create a similar shape to the whitney.
The latter includes 1″ sq. and round, 1 1/2″ round, 1 1/2″ x 1″ rect, plus numerous others.
Having seen a side mounted marine engine I decided to adopt that into my engine instead of the base mount.
Had it running recently on air, it’s on you tube at bobbie jones small marine style engine if you would like to see it running.
Inside the alloy there are cast iron liners in the cylinder and cross head guide.
More details on request
