I am having an issue with our Uni I—it has a squeaky rider roller.  I took a look at an old post, ‘Inking Roller Squeal,’ and that was helpful, but I have an additional question.  The black knob at the end of the rider is loose, but when it is held in place, the squealing [...]

NEW CONTENT AT BOTTOM The problem I am having is that I can not see how to remove the distributor frame. It is wider than the frame which holds the mechanism to raise and lower the roller assembly. I can raise the distributor frame about 1/2 to 3/4″, but since it is partially in front [...]

Hi Folks – I know that I use one of the “knock offs”, a Challenge 21MP (similar to the Vandy SP15), but I’m up poop creek without a plunger. I am calling on the collective wisdom of this group…. I’ve been restoring this press (some rust – lots of gunk) and have run into a [...]

The Book Arts Program at the J. Willard Marriott Library, The University of Utah has a Vandercook 15-21 (shown with the top frame assembly removed) that is experiencing difficulties. Within minutes of application, a majority of the ink added migrates to the non-operator side (highlighted in the image) of the ink distributor assembly and form [...]

I have been perusing the posts related to #4 form roller problems, specifically in regards to the clutch plate. I finally got a good handle on the source of all the racket that my press has been making for the last few months by adjusting the roller assembly and shimming the clutch plate. The issue [...]

Can anyone provide a picture and approximate dimensions of the bullet catch that holds up the ink distribution rollers for cleaning on a Uni I? Ours has gone a-miss and I have a VERY KIND friend willing to machine us a new one–but I have no idea what it looks like!

Rather suddenly my rollers decided to crap out by not inking the form evenly. I am using photopolymer plates. The Problem Form is not being inked evenly. Ink is heaviest at the beginning of the form (the area the form rollers hit first). Based on the image above, it appears that the rollers are not [...]

Hi there—This is my first post. I have an SP-15 (serial #26151), and I looked through my manual, but am still unsure of the part names. It appears the gear on my motorized roller is broken. This is the gear that the belt / pulley (?) runs on to actually move the roller. For clarity, [...]

A prelude leading up to a repair question- I am restoring a Vandercook 4, serial # 10877, that I’ve had for a few years now. I’ve been mostly removing accumulated layers of ink, grease/dust and mild rust, and lubricating moving parts. With a couple of exceptions nearly everything appears in order. One of the first [...]

Do any of you #4 Vandercook owners have any side play on your ink drum? That is, when wiping from side to side, does the drum move a little, or not at all?

I sent my form rollers to be recovered and got them back without the MR-110 pin that goes into the end of the shaft, the one with the rounded head that connects to the gear clutch. The roller company says they never saw them. When I prepped the rollers for shipping, I stripped off the [...]

Hi, I recently obtained a vandercook that is in pretty rough shape and missing a lot of parts, although still great for what I need it to do. I have the two inking rollers that are supposed to be mounted together with the oscillating roller (excuse the made up terminology), but they aren’t usable anymore. [...]
