Got back on track with the 10V this week. I got to the stage where I had finished the crank and con rod. This was a real pain because the con rod had been started, the only piece that had been touched on the entire set when I purchased it second hand (strange place to start?).
So got to here:

I then machined the cross head which was quite straight forward and also started the piston rod.

The following video just shows the con rod and cross head running and then with a second video of the piston rod running through the bottom cover (I was worrying about the bushing I had to do). But I`ve since had it turning with the piston in the cylinder earlier this evening.
