Car Baler

Sierra RB6000

At first I made the jaws open wide...

...but they didn't close all the way.

This happened because the movement of the pistons in the small
pneumatic cylinders is not 2 studs as I had thought but a little less.

I had to move the hinge points of the cylinders for studs.
The jaws don't open the whole 90 degrees any more but so is the
case with the real one too.

I found these pictures from the net. If they are yours and you
don't want them to be here just e-mail me and I'll take them away.
