Also some final sanding and polishing was done on the piston. Photo #2 shows the Watkins piston completed and waiting for new piston rings...


These (2) photos show starting to get the Braden piston in the lathe for turning. The first operation is to clean up the back side of the piston. Photo #2 shows taking a few passes on the back side of the piston. Note the over spray of material on the connecting rod. There is a release agent painted on the connecting rod before metal spraying, so this over spray will clean right off...

He has done a great job restoring his engines. Hope you enjoy the photos...
