The press? A Universal 1 manual. The problem? A severe case of an undercut cylinder. How sever you ask? Say your normal depth of cylinder on a Uni 1 is what? .040 inches? .070 inches? This Uni? .160 inches. What packing can fill it? What top sheet can hold it?
What am I using for packing? .020″ blue board, .010″ mylar, .006″ & .002 Vandercook tympan paper. The grain direction of each is doing what its supposed to under the topsheet. be doing, getting around the cylinder and under the topsheet. Trouble is, the packing won’t behave well enough where the topsheet fits in at the gripper assembly. It’s a jump even Evel Knievel would fear, making registration a worry I hate worrying about. Plus after a few impressions the top sheet begins to looked pretty worried itself right at that edge compromising fold where it meets the gripper assembly. Try two top sheets you say? HA! It will laugh at you and call you names if I shared your suggestion with this unruly beast.
Here’s my thought (and now tell me if this is rock stupid, okay?) I buy a diecutting jacket and (time to fess up, I’ve never seen a diecutting jacket for a Vandercook so yes, I am talking out my keister right now) and I put a healthy portion (how about .090″ = 4 blue boards & 1 mylar) of the .160″ packing under that. Plus the jacket itself would take up some room.Anyone know how thick? .050 inches maybe?
To anyone with Vandercook diecutting jacket experience: Would the jacket be strong enough to strap the packing down from end to end securely? And if it did, would it seem ludicrous to then act as if everything were normal and build up the normal .070″ packing with the standard issue .006″ Vandercook topsheet?
Why ask such a stupid question? Cause such a press exists and it’s in my care and I’d like folks to be able to use it. Plus . . . aren”t those Vandercook diecutting jackets sort of expensive? I’d rather look before I leap into buying one if this idea is buckshot full of holes.
Other than that, gang, any other possible solutions are welcome. Now amaze me with your wit, wisdom and candor. Moxon? . . . that leaves you out.
