I need some feedback please. We use a Reprex II in our studio. During the last class, last 15 minutes the carriage would stop mid travel like it hit a brick. Checked all the usual culprits- something on the gear track, high furniture, bad lock up, etc. Even changed some furniture to make sure none […]
More320G oscillating roller problem
I’ve been having some problems with the oscillating roller on my 320G. It would stop rolling and begin to chatter as the cylinder traveled across the bed. When the cylinder changed direction it would begin to roll normally again. I think this condition was caused by the worm gear and/or crescent. I adjusted the screw […]
MoreOld Style Rider Bushings
Greetings Paul and Vanderbloggers (First post!) I’ve acquired a Vandercook No 3 – OS (green) model. Serial is #9403 (currently registered to a previous owner on the census). While already functional, I am in the midst of typical maintenance/rehab and becoming familiar with this particular model. First issue: This backside rider roller (Part M-123) is loose/large […]
MoreSP-15 roller grinding sound (pictures and video)
I am having trouble fixing this sound. I believe it is being caused by the gear on the inner form roller when it travels over the form roller rack teeth. See the video to hear the sound. This happens in trip or print. Vandercook SP-15 grinding sound (YouTube) Here is a photo of the gear […]
MoreExcello Proof Press
This display ad appeared in most issues of Graphic Arts Monthly, vol. 1, 1929, but does not appear thereafter. Neither was it advertised or mentioned in The Inland Printer or Photo-Engravers Bulletin before, during, or after 1929. (Perhaps, there wasn’t enough interest in this product, and likely Black Tuesday—the infamous crash of the stock market on […]
MoreInk/impression issue on SP-20
I’m having some issues with a print I’m working on today. It’s a long form (photopolymer) – approx 17” – that I’m running vertically. I’m using photopolymer on a solid wood base that’s shimmed with chipboard up to type high. Printing on Lettra 110 with black ink. The initial couple of lines are very heavy, […]
MoreAdjusting Cams on Universal I Power
I have a early model Universal I Power that I have recently purchased. When running the automatic carriage it has a tendency to slam into the end of the run and upon returning to the feed board slamming into that. I have adjusted the speed and the brake using the dials on the operators side, […]

MoreTwo Early Custom Vandercooks
Here are two very large proof presses specially designed by R.O. Vandercook, and built by Chicago machinists Reichel & Drews, circa 1912–14. While neither press is known to exist today, they demonstrate that Vandercook was able to satisfy specific client requests early in his career as a manufacturer. The illustration at left, accompanying an article in the June […]
MoreSP-15 Gear Roller Grunt
One of our SP-15s makes a sort of grunting noise as it travels down the bed. I suspect it is the gear on the back form roller, but I cannot see any issue with it. The other SP-15 is silent during this travel, and this noise is new, so something seems to be out of […]

MoreGummy SP-20 rollers
After acquiring, I did a thorough clean-up the ink rollers on my SP-20. That was months ago, and they have remained somewhat gummy, tacky to the touch. At first I thought it was due to the humidity, but that’s no longer an issue. They were pretty crudded up & I gave them a good scrubbing […]
