Inline Twin Engine Ep. 13

The flywheel for the engine is next.

It is a straight forward turning job. Here, the first side is done:

Inline Twin 196 (800x450)

The flywheel is turned over and the second side is finished:

Inline Twin 197 (800x450)

The finished flywheel:

Inline Twin 198 (800x450)

As a contrast to the mostly aluminum engine, I decided to cold blue the flywheel. Hopefully this will also help a little with corrosion protection.
I used Brownells Oxpho Blue, and I’m happy how it turned out. It’s not as dark as a commercial black oxide finish, and has more of a blue tint to it.

The flywheel installed on the crankshaft using a taper locking assembly.

While I was bluing the flywheel, I decided to give the rockers the same treatment:
