Selling our Challenge 15MP proof press located in Houston TX. This model is for all intents and purposes identical to the Vandercook SP-15. Powered inking, galley height (includes bed plate), 11 x 17 form.
Great shape, 100% functional and is regularly used. Rollers are not new but print acceptably, no breaks or welded repairs. Some areas of chipped paint with minor surface rust but nothing functionally wrong.
Can arrange shipping (at buyer’s expense) or load onto your trailer.
Looking for $6,000

I recently acquired a Universal 1 and have a couple questions related to maintenance. I have been keeping the rollers raised by raising the lever for that purpose when the press is not in use, but wasn’t sure if I also needed to raise the oscillator and a single rider fully away from the rubber rollers (as they would be for cleaning) when the press isn’t in use as well? I ask because I’m having some inking issues that recently arose (it was inking just fine before) and I’m worried that it might be that I’ve damaged or flattened the rubber rollers by not having the press in the correct position when not in use. From the manual it sounded like they just needed to be raised with the lever and I’ve never seen presses kept with the oscillator up but just wanted to make sure.
The inking issue that has recently started happening is that the rollers are inking the first part of the form more heavily than the center. I’ve checked the height of the rollers and they seem fine (though I didn’t check the height of the front and back rollers separately by taking off the first one, so maybe that is it?) It was inking beautifully before and I’m using the exact same ink, paper, and polymer plate. It’s definitely an inking issue and not a packing issue, as I can see it on the plate, and it happens at various placements on the bed and with various plates. Any thoughts about what the issue could be would be most appreciated! Could it be that the roller isn’t rotating properly over the form and therefore only inking the beginning of the form and not the rest? How do I fix this? I’ve been trying to troubleshoot it but have reached the edge of my knowledge. I have visual examples if that might be helpful in explaining.
Thanks so much!
hello! i’ve attached a couple of short videos and images of the problem i’m experiencing as printing today on my universal 1. basically, as the vibrator oscillates, it is actually pulling the core of the front form roller out of its bearing block on the right side, so that the roller is coming in contact with the rail on the left side. the person who was printing didn’t notice at first, and the left edge of my roller got shaved against the rail. :( now, we’re working around by lifting the vibrator each time, to make sure the form roller core is all the way in its socket, then pulling a print (obviously very time consuming). has anyone had this problem, or have any idea how to fix?
when i take the form roller off, i can easily slide the sleeve off, as shown in the images. i tried stuffing the sleeve with teflon tape, but it just gets torn up. there is no way to adjust the ring to be any tighter.
i appreciate any help! (and excuse me if i’ve gotten some terminology wrong, still learning.)
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 of the form was too high. Could not find the cause. Then I looked inside the carriage and noticed the slotted “holding pin” (photo attached) sticking up high enough to catch the guide bar when the carriage reached one complete turn down the track. I was able to push it down so it cleared the bar and we finished printing. Later I went back and screwed it all the way down. It is part of what I would call a collar or clutch which is supposed to be free moving and part of the guide release mechanism. It did not seem that the main shaft had a groove for it to fit in nor should it be screwed all the way down because the collar could not move. It probably has a spring in it. My question is does any Vandercook have a similar mechanism and what is it function? Thanks.
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 that covers the crescent and lubricated the gear. That seemed to help but didn’t totally correct the problem. The cylinder would travel 8 or 9 times with the oscillating roller working properly then all of a sudden the oscillating roller assembly would jump off the roller assembly. When I put it back on it works fine again for 8 or 9 trips then jumps off again. I don’t know what is going on. Any help would be greatly appreciated.
I have tried to take the crescent out so I could exam it but I can’t figure out how to do that. I took the set screw out (the one with the allen head, in the end of the roller) and I removed the screw that covers the crescent. There is a slot at the end of the oscillating roller that seems like the crescent should fit through but i can’t get it out. Can someone tell me how to remove the crescent? Any help would really be appreciated.
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 — cause by the interior of it disintegrating (there was some black gunk falling out of it). This obviously affects inking. I’m not even sure how to take this apart (if I can).
Question: Can this be replaced, modified …or do I need to look for an entire new roller carriage?

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.
Here is a photo of the gear on the inner form roller. Is there a specific adjustment, or exact location of this gear? I adjust, and re-adjust but I cannot get it dialled in nicely.
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, the there wasn’t enough interest in this product, and likely Black Tuesday—the infamous crash of the stock market on October 29—prevented the manufacturer from subsequent advertising.
With its tapered pedestal, the Excello, a reciprocating bed press, looks similar to a No. 0 Potter proof press (at right), which likewise has neither paper grippers nor an inking assembly. On the Excello, notice the low position of the hand crank indicating that it drives the underside of the bed instead of the impression cylinder as is common with reciprocating bed presses.
Established in 1926, the Excello Machine Co. had by the early 1940s specialized in converting Miehle production presses to die cutters. They also fabricated a hand-fed letterpress (platen?) which was marketed throughout the U.S. In the 1950s, Excello became a dealer for the Miehle Co., which imported Man Roland offset presses and is still in business, servicing these presses.
An email to the company did not yield a reply. Records on this machine have likely been lost and no example is known to exist. Excluding Vandercook, there are now 37 other makes of proof presses in the Known Brand List.
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, inkwise as well as impression, but then within an inch or two the ink becomes more consistent, although not dark enough. I tried rotating the plate and running it horizontal, but I just got very hard impression and overinking on the leading edges as well as the opposite edge of the type. I’ve adjusted my rollers to type high as well. I have a rider roller for the press, but I’ve never used it and am not sure how to attach it, in case that might help the situation.

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, but think I need to adjust the cams (is this the correct term) on the other side.
Question is, how in the world do I do this? Is there a way that Vandercook suggest to get the most middle of the road action? I have pictures of how all four are set up and each cam.
Please note: one of the previous owner in their amazing wisdom decided to spray paint this press a disgusting dark grey and when they replaced some of the the labels on the cams they did some upside down.

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 1912 issue of The Inland Printer, represents a massive press custom-made for publisher R.R. Donnelley & Sons. Weighing ten tons, and requiring a 7 × 18 ft. floor space, its printing surface was 66 × 44″ bed. Note that the impression is made when the carriage travels to the left. The hand wheel is also off-center behind the impression cylinder. The inking assembly appears to be similar to the ink carriage style that was standard on Vandercook’s composing room cylinder series (Nos. 17, 25, etc.), The Donnelley archive (at the University of Chicago) makes no reference to Vandercook.
