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. […]

Challenge 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 […]
MoreMore TagWhat 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.
MoreMore Tag4c 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!
MoreMore TagNo. 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 […]
MoreMore TagSP-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 […]
MoreMore TagRoller Height Differences along Length of Bed?
I’m still running into problems on my No.3 with respect to roller height and I haven’t seen anyone else having this issue. I’m using a type-high gauge (from NA Graphics) on top of a cold-rolled steel 18-gauge plate. I set the proper roller height where the start of my Boxcar Base would be, then roll toward […]
MoreMore TagNo. 3 Form Roller Lift Arm Bracket
Hello all– Wondering if there is a rule of thumb for bolt placement in the slot for the lift arm bracket on the No. 3 (and why there’s such a large slot in the first place)? Do I need to adjust those in some way before I start adjusting my roller height (e.g. on one side of […]
MoreMore TagSP15 form roller slipping
I have a friend who has an SP15. She was having trouble getting the inking smooth and I stopped over to see if I could figure it out. Turned out that the roller and the drive gear were acting independently of each other. Once it was printing the gear that should drive the form roller […]
MoreMore TagReprex No. 2 Missing drive gear
I recently acquired a Reprex No. 2 [No. 1] proof press. While everything on this Reprex appears to be in excellent shape, it is in fact missing the drive gear on it’s form roller. The original manual I have specifies that there should only be one drive gear, and the part number for this gear is […]
MoreMore TagSP-15 rollers hesitating
Right before the holidays I was finishing up a print job and noticed the the rollers didn’t want to turn with each other anymore. I thought it was the ink drying as a result of the heater blowing close to the press area and didn’t think about it again. After being off for a few […]
MoreMore TagSP 15 Rollers Condition
I bought a SP15 a couple of years ago. The rollers were/are clean and seem to work fine, but they are shiny and quite hard. However, after reading a recent post on Briarpress about cleaning rollers I wonder if mine are glazed and need to be deglazed (or possibly recovered). Certainly, the rollers are not […]
