A proof press resource
I am working on a Vandercook No. 4. The carriage does just fine engaging in print and trip. However, the carriage will not stay put in the home position. On the opposite side of the operator, there is a broken spring that is keeping a latch in place. I wonder if there is more to […]
MoreMore TagI’m in search of a diagram or photos of the non operator side of a vandercook 4- specifically the mechanisms that catch and release the cylinder- the screws and parts keep loosening and occasionally bend- resulting in the cylinder not locking in place and the grippers not performing correctly. I’ll attach a few pics here […]
MoreMore TagHi all, I’m teaching on a Vandercook 320G that is still relatively new to the school, and working on tuning things up. One of the main issues is that the carriage will not stay in its resting home position unless it’s held in place. After a print is pulled, upon returning to the starting point, […]
MoreMore TagI thought I’d give my Universal III a good cleaning after it had sat idle for a good deal of the winter while doing some home remodeling. I started out cleaning out the gear racks and noticed that the carriage latch was pretty loose and no spring tension. I pulled it off and found the […]
MoreMore TagHi Folks, Sorry if this has been covered before… Haven’t printed on this machine yet, but in the course of general lube and clean-up, I detect one issue: in the home/start position, the carriage doesn’t quite sit well-settled to the left/feedboard. it wants to roll off of the correct home/detente position and almost begin travel. […]
MoreMore TagWe have a No 4 (S/N 8655) that seems to take more effort lately to return the carriage to its resting position at the feed table. There is no problem leaving the feed table in trip or in print. Returning to the feed table seems fine in both trip and after printing an image until […]
MoreMore TagI’ve been talking to Fritz about this and he suggested reaching out to see if anyone else may have some measurements. My 219 OS has a wooden block acting as the carriage latch. Now that my press is properly leveled it’s clear that the wood has worn away and it’s no longer holding the carriage […]
MoreMore TagHi, I have the press basically back together and I’m starting to get things reset so that I can start printing. Some quesitons on how to do a few things: 1. How can I determine the amount of packing needed on the roller [impression cylinder]. 2. inking rollers that are on the oscillating roller group […]
MoreMore TagMy Universal II has all of a sudden stopped locking when it returns to the feedboard. Therefore when I press the trip pedal nothing happens (grippers don’t move) and it makes a sharp ‘bang’ noise releasing the tension of the pedal… Thoughts? Trip spring? Please help. Thanks, Adrian
MoreMore TagI think I might now what the prob is, but wanted to hear what others think. The spring under the latch that holds the cylinder back and in place that is not the original spring. I faked it with a purchase from a hardware store 7-9 years ago. Well, it seems that its time has […]
