My buddy Monty and I have been for the last 2 months been scratch building a pair of Allman Gas Engines from Drawings from Debolt Machine . I bought the drawings many years ago but Never bought the castings . Thinking one day I would just build one from bar stock . Well we finely got around to it.
I machined the main body's and fabricated the cylinders with a welded construction and a cast iron liner.My buddy made all the loose pieces and I machined the flywheels and made the wooden bases and built the Buzz coil`s. Got them running last week but waiting on some fittings to finish the radiators. Here are some photo`s.

You machined the fly wheel? looks like a casting the spocks do

Nice job! I've admired those Allman engines and keep thinking I'd like to have one. Too many other irons in the fire, though.

Thanks for sharing!

You are correct the flywheel were castings .The only one`s used we bought them from Deboit Machine . But you still have to machine them.
