AH, i see, just to balance the pivoting arm!
I thought (and still do) the car shock absorbers were intended to be used
as linear slides for a non-pivoting type of press.
I don't think it is very difficult to find a spring, and a counterweight
on the back of the arm works well here, but a rubber ball of some sort
would surely work as well. I reckon even rubber bands can be used if some
standoff mechanism is used.
