BUILDING THE SIMPLEX PETROL ENGINE

Part 1 by Phil Procter



Here are the castings as purchased in an assorted box of junk on ebay.

I was also lucky to find the drawings and the pair of skew gears needed.

A start was made on the crankshaft. Set up on a rigid post mounted on my own design of low height indexing table, it allowed a few faces and holes to be done with minimal re-setting.

.


And using a boring and facing head to machine the register in the top face for the cylinder.
