Scratch-built 1:6 scale Benz BzIII
« on: August 31, 2016, 07:07:23 PM »
I'm currently building a 1/6 scale Albatros CI and the particular aircraft I'm modeling had a Benz BzIII engine.  Building this dummy engine became a whole project in itself. 

One curious feature of the BzIII is that the cylinders were not centered on the crankshaft but rather offset.

The first task was to create a master for the cylinder resin castings.

The basic (water jacketed) cylinder was then smoothed out and detailed.

This was my first time trying casting of any sort.

The castings were not super clean but were usable.

They are heavy for a flying model so I drilled out the center.

Next they were mounted on a ply base that will be mounted over the actual engine.

And lots of hand-cut G10 flanges.
