Danni build - February 15: Brazing the crankshaft

Trying soldering and brazing

More parts today, along with trying some different soldering and brazing processes. The engine uses brazed connections in a few places; one of them is the crankshaft.

The crankshaft, piston rod, cylinder, endcaps and smaller parts laid out on the bench — More parts taking shape, including the crankshaft.

Making the crankshaft opening

Here is the crankshaft in progress. The rod is cut away between the crank arms to make the opening; it is the lower rod in the vice in this photograph.

Close view of the crankshaft held in the vice, showing the rod to be cut between the crank arms — The crankshaft held for cutting the opening between the crank arms.

Cleanup and final cuts

The crankshaft looked rather dirty after brazing, so it needed some cleanup and the final cuts.
