Shim the balance rail when possible to avoid springiness caused by an exaggerated stack of paper/cardboard punchings. Also use the thickest card punchings possible. My rule is that if it takes more than two punchings of the same thickness, it requires a thicker punching. Start with the thickest punchings and progress to smaller punchings during the leveling process. -- Regards, Jon Page ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
