Hello! I have been wondering about proper packing on my SP-20. I have a Galley Bed Plate with 040 cylinder undercut. I have Vandercook Tympan, .003 packing sheets and a Mylar sheet.
Everything I can find as to how much packing you need does not mention if the thickness of the bed plate is involved or not.
If I use one piece of Tympan, the mylar and 5 packing sheets. Its not enough to make an impression in 80lb lettra.
Im worried that if I add any more thickness to the packing I may be counterproductive. and of course I do not have a micrometer (Yet)!
Any advice would be great.
