Has anyone had experience using a split roller that allows for two different inks to be used on a single print run? Is it worth retrofitting a Uni to cut the printing time in half? Thank you for your thoughts!

What Vandercook does this clamp bar go to?
I am trying to figure out what press this tympan clamp bar comes from. It doesn’t fint my SP-15, the Uni I has a slotted bar, and it is too short for the Uni III. Any ideas? It is 14 inches long, the outer pins are 11 1/2 inches on center, and the innermost two […]
MoreLubricating the gear teeth on the Vandercook No. 4 impression cylinder
Hello. I am a newbie in the process of restoring a Vandercook No. 4, SN 18794. My husband, who was in aerospace mechanical engineering for many years, is providing advice and much moral support. He was surprised when I told him that the procedure for lubricating the impression cylinder gear teeth was to apply a […]
MoreVandercook No. 3 Carriage Help
Hello. I recently had my Vandercook No. 3 overhauled with a new paint job. While the press looks beautiful, the carriage with the cylinder no longer “locks” in place. I think something mechanical was painted over that should not have been, so if anyone has any suggestions about which part on my press is affected, […]
MoreSP20 Trip Spring Repaired
I recently repaired an SP20 at the University of West Georgia on which the carriage had become stuck during the return travel. The photos above shows that top carriage bearings on the operator’s side had been removed during a previous repair attempt. Typically what happens on SP series presses is that the trip spring inside […]
Morebroken spring on an SP-15
hi all I’m calling on the fount of collective knowledge here with a technical question. I’m refurbishing an sp-15, and as I was cleaning up the underside of the cylinder carriage I noticed that a rocking lever arm (what is I assume part of the trip mechanism) was sprung with a flat spring on one […]
MoreTindeck?
Can someone tell me about the characteristics and specs of a “tindeck blanket,” the original packing specified for the impression cylinder of my No.2 Proof Press, according to the model description on the vandy site. Just curious, never having come across one. Thanks, Duncan Dempster Honolulu, Hawaii
Morecylinder gear tooth alignment
After reading the previous discussion about a misaligned cylinder causing the grippers to smash the form, I thought about the SP20 I’m currently going over (and on which we have not yet printed) and noted that when I received it, the gripper bar was not at 12 oclock when the cylinder was home at the […]
MoreVandercook 4 problem
I have printed a couple of projects on a Vandercook 4 that a friend recently purchased. I have had to put 4.5 picas of furniture in back of the deadline bar because if I were to put type or engraving at the deadline bar (without the furniture) it would smash. With the furniture in, this […]
MoreGrippers snap closed when cylinder is at feed board…
I am trying to work out the quirks in one of my 320G presses and the thing that is bothering me the most is that the grippers are closing when the cylinder reaches the feed board. The gripper pedal won’t open them at this point. The gripper bar stops at the proper vertical orientation, but […]
MoreNo.4 Cylinder Engineering Print
Fritz sent me this drawing of a No.4 cylinder showing its position at the feed board. It is posted for the benefit of Klu, and other tenacious individuals who dare to restore long-abandoned presses from which lesser mortals would have walked away. –PM The excerpt below was originally posted 10-11-06 by Paul Moxon on “PPL”:http://groups.yahoo.com/group/PPLetterpress […]
MoreCylinder Undercut Variables
[In a previous post I stated that all 4Ts have an cylinder undercut of .070″. —PM] Just to add my two cents, my 4T cylinder is undercut to .070″ as are the other 4T’s at the Wells Book Arts Center. … I’m curious why a Uni I manual at the Center would have been undercut […]
