I seem to be having an issue with one of the bearers (is that even the right term?) on the rear form roller on my SP-20. I can’t lower the roller height to type-high on that side. I can on the user side, but not on the opposite end. No problem with the front roller. […]

SP20 Form Roller Screws
I’m attempting to remove the hardware from my SP20 roller cores to ship them off to be recast. I’ve removed the tiny set screw from inside the larger, outer, screw on the end of the roller, but now I can’t seem to remove the larger, outer screw. I don’t want to turn it too hard […]

SP15 “bearer controlled form roller support system” + nylon wipers
I’m hoping to clarify a few SP15 related mysteries. Apologies in advance for the multiple reference photos….
MoreRecasting Rollers
Hello All, In a few days we’ll be sending out the cores for our SP15 and SP20 form rollers to be recast. Would it be a good idea to have them recast at a slightly larger diameter (perhaps 2.51 inches for the SP15 and 3.01 inches for the SP20) to make them last a little […]
MoreRollers stop spinning
Hello, we have an SP-15 used by college students in a typography studio. A problem occurs with the rollers when you move the carriage over the the bed. To start the rollers ink up fine and evenly, but as you begin to turn the carriage handle all of the rollers suddenly stop spinning. They seem to […]
MoreChallenge 20 KP Rollers
Hello, I just picked up a Challenge 20 KP and the 3 rubber rollers are shot. I would greatly appreciate any info such as size and durometer so I can replace them. Thanks, Coby
MoreNew Rollers Slightly Different Diameters
Hi All, I just received two newly recovered rubber rollers for a #4, done by Rotadyne. I measured the rollers and one is bigger than the other in diameter by 1/32″. One roller is 2 1/2″ and one is 2 1/2 plus 1/32. I asked the roller company to make them 2.515″ in diameter. Should […]
MoreFlickr set – Installing new form rollers on a Vandercook No. 4
Continued thanks to everyone who has the patience and takes the time to answer the many questions that we relatively new printers come up with. I recently asked for step-by-step instructions for installing new form rollers on my No. 4, and the replies I got were extremely helpful. I put together a Flickr set on […]
MoreNew form rollers for a No. 4
Hello Vanderfolks, I just had the form rollers on my No. 4 recovered. A very nice gentleman from RotaDyne came to my house to pick up the old ones. He took the whole assembly with him, and they shipped everything back disassembled. I’ve looked through the archives for instructions on putting things back together, but […]
Moreretaining screw problem for my sp15 cores
I recently had my second set of cores recast. In switching out the hardware I cannot for the life of me get the retaining screw to grab and screw in to the new core. I have tried solvents, wd40, a wire brush, an awl and curses, but to no avail. I’ve tried all 4 ends […]
MoreInconsistent print quality
I’m sorry for having problems two days in a row, but here’s another phenomenon that I’m not understanding. These two drop caps (48-point Rondo) were printed one after the other – same lockup, same ink, same paper, same packing, same everything – yet the print quality is markedly different. What could have made the difference? […]
MoreUniversal I back rubber roller and gear backwards?
I was using a friend’s Universal I press today when I noticed I was getting a lot of slurring and that the rollers weren’t rotating at all when I was printing or tripping. They were dragging across the surface of the plate without rotating. I looked up the manual and am wondering now if the […]
