Piston/crank test

I have redone the pistons and rods quite a bit since the last post. The rods now connect to a pin I installed through the middle of the piston head and rotate in a slot I cut in same. This is more like how real pistons work and limits (or ideally eliminates) the ability of the rod to impart a torque on the piston head, which would cause it to bind.

Additionally, I used a longer rod and removed the lever between the rod and the crank. This lessens the angle of the rod to the side of the cylinder, reducing the risk of the rod contacting the cylinder, and also reduces piston head torque/binding.

Below are two close-up pictures of the piston/rod connection, and there is also a video showing the motion of the piston when connected to the crank.
