Here are the latest WIP photos of my 1:8 Hispano-Suiza H-8 aircraft engine. This is the engine used in the SE-5 and the Spad VII. It is completely scratch built.
I still need to do spark plugs and ignition wiring, the prop shaft and hub, and mount the propeller, and the exhaust stacks.
No, I haven’t worked on the 3D printer in a long time. Construction is done but I have to install software and initialize everything. Just haven’t gotten around to it.
Nothing on the Hisso is high tech- no PE or anything. Only out-of-ordinary work was turning the magneto couplings on a lathe. Most of the model is wood- crankcase, cylinders. Smaller assemblies are multi-media (styrene, some brass and aluminum).
Yesterday I got exhaust stacks done ready for painting. Made 4 spark plugs- only 12 more to go (engine has complete dual ignition- must have been one of first).
Somehow, when I post the link becomes just text. Don’t know what is wrong- maybe just going to the aircraft forum and looking for the Hisso thread is the easiest way to see it.
