I just got brand new rollers and cores. The weird thing is that when I check my roller height, it’s not even throughout. The ends are the same but the middle of the roller has a thinner stripe when I check. Is it the gauge I’m using? That’s steel but I’ve heard that those can […]

Reprex No 1 Rollers Specs
I just received a request for the specs for the cores for a No 1 Reprex. this is the same one posted on Briar press. I will make a drawing and share a pdf on this site. I need: – overall core length – diameter and length at ends – other diameter and length on the core – position end to end and length of rubber on the core […]
MoreVandercook 4T Roller Issue
I have a Vandercook 4T press here in Prague. Now after 5 years of not being used (here in Prague – it could have been unused for longer than that), I have decided that I should give it a go. I had to change the plug, but all seems to be working fine, apart from […]
MoreNo. 4 Uneven Inking on Rider Rollers
Hello all, I’m trying to troubleshoot an inking problem on my Vandercook No. 4, Serial No. 14509. I’m finding that my rider rollers (the small steel rollers front and back) are not getting inked evenly. (See image, the front rider roller is not completely inking towards the right side) When I roll the cylinder down […]
MoreUniversal III roller gear issue
I have taken a break from printing (it’s been 4 years) and now I’m ready to get back into it. I took pretty copious notes, but for this issue, I can’t remember how to adjust or what the problem is exactly. This piece that’s circled keeps coming loose when I put the rollers in and […]
MoreUniversal III Roller Height
I need to adjust the roller height on our Universal III and am wondering if there is a trick to it. I was able to turn the knobs on the back rollers slightly, enough to get to a good height. But the front roller knobs do not move at all. Wondering if there is a […]
MoreNo. 4 T, difficulty removing collar from form roller core
Hi everyone, I am hoping someone here in the Vanderverse can help. I need to remove the hardware from both form rollers on a No. 4 T (#14205) and both MR-112 collars (and I!) are stuck. The collars could be cemented from grime/grease accumulation. Before using force I wanted to check in with the group. […]
MoreChallenge 15MP Chatters
My daughter has a Challenge 15MP. Sometimes when she returns the carriage to the feedboard, the gears “chatter,” that is, the gears are not matching up and it makes the carriage shake. I’ve looked at it and don’t see anything obviously wrong. I did note that she does not turn the power inking off when […]
MoreWhat Durometer for Form Rollers for Hacker (or Vandercook)?
I am in the process of purchasing a Hacker 4, and would like advice on what durometer measurement the form rollers should be for printing mainly type or photopolymer plates. Perhaps the durometer would be the same for a Vandercook press. Any advice would be welcome.
More4c Roller Diameter
Hi all, Would anyone be able to confirm that the #4c, made under licence in the UK has the same roller diameter of 2.5″ of the #4? I’m assuming that it does, but thought it best to check before I get them recovered incase they turn out to be wrong. Better safe than sorry!
MoreNo. 4 grinding chatter
We have a No. 4 who is the work-horse of our print shop (at MCBA). In recent weeks, it has started an awful chattering noise, that continues to get worse. At first I thought it was the gear and the clutch on the form rollers that were rubbing together. But on closer inspection the gear […]
MoreSP-15 Roller Bracket Issues
One of our SP-15s has been experiencing inking issues; seems that we have to constantly adjust roller height and it gets out of whack very quickly. We discovered today two problems with the bracket that holds the roller bearing blocks (LH Bracket? Hard to see in our manual) and we’re wondering if these could be […]
