Hope that's allright with Kevin. Great if GrabCAD could be source for students to see how professional designers have built their models.

Great model Ken :)))
Hi William, That's great by me. The only thing is that the piston is a "dumb solid", which I scaled to meet the cylinder bore requirements. As a result, diameters for the rist pin are incorrect.
Have fun!
Ken
