[QUOTE="ClassicBiker, post: 93623, member: 1632"] The piston shape will influence the position of the rod. Especially if you have some kind of lumpy piston. In my drawing, which I admit is extreme, the vertical line represents the cylinder wall. The angled line represents the line of action of the plunger in the tool. The horizontal lines represent the crown of a flat top piston, the arcs a domed piston. As the flat top piston descends 0.25 inches the tip of the move horizontally 0.25 inches. The total movement of the tip of the plunger is 0.354 inches. If say the crown of the piston has some shape to it. In this example a simple arc. The upper arc is centered on the upper horizontal line. The bottom arc is centered on the lower horizontal line. So the vertical distance is still the 0.25 inches. The total plunger movement is 0.089 inches. Unless you know cross section of the crown, I would degree is at least once. Steven [ATTACH=full]20949[/ATTACH] [/QUOTE]
