Building the Prototype AMD Series Engines

Crankshafts

The blog is slightly out of sequence as I made the crankshafts for the single cylinder engines some time ago, but I am catching up now.

The cranshafts are built up with the shafts fixed to the webs with Loctite.  A reasonable degree of precision is required to align the separate portions of the shafts and to achieve the correct diameters.

Here are some pictures.

Shaft sections.

Shafts and webs ready for assembly.
