More engineering - started a new part.

I did some work on the cylinder heads today, and drilled and counter bored the ports for the inlet and exhaust. They're finished now, apart from the holes for the rocker shaft. Check out the pictures:-

Cylinder heads very nearly finished

I started the gearbox, not much done yet, just the flange face, location diameter, bore for the bearing, and clearance drilling for the primary gear.

Gearbox started
