My friend Lee and I printed on the Challenge 15MP at BAD today. It was for a job, but I used it as an excuse to get a second opinion on the press and to try to troubleshoot some things. The press has some relatively new rollers on it, that were certainly made badly, which […]
MoreSP-20 Gripper Pedal Doesn’t Come Back Up/Grippers Not Raising
Hi folks, Asking for some help! We are having issues with our gripper on our Vandercook SP-20 (serial number: 23442). The grippers were getting lower and lower and now do not really raise at all. The foot pedal was also pretty low to the floor, with us having to press harder on it for the […]

I recently had to remove both trip springs from my SP-15. I approached each one differently, so I’ll explain both methods. The discovery that not just one but both springs were broken came a couple months ago, but it took some time to procure the right tools for removing the old springs, namely a cold […]
More#4 trip rack reinstallation issue
I am having trouble getting the trip rack to raise on my Vandercook 4. I removed the trip rack to access the cylinder eccentric adjustment today. I removed the rack while the carriage was in the middle of the bed. I put the rack back together afterwards and now the rack won’t fully raise when […]

The roller height is now identical in print and trip, but only while the carriage is outbound, i.e., moving away from the feedboard. Once it hits the trip mechanism and I roll it back, the rollers are a touch lower […]

Would anyone happen to know the power consumption of the SP15 motor? Thanks, Adriaanh
MoreSP 20 chain problem
Today while printing our SP 20 started making a metallic dragging sound. It stops when the motor turns off and gets louder when the carriage is at the feed board with the rollers down, when there is pressure on the ink drum. I suspect that it’s because the chain is stretched or loose and is […]
MoreGripper stem closest to printer stuck open
The gripper stem is sticking open on the last gripper nearest the printer. I’ve taken the mechanism off and applied a bit of lubricant from the bottom but it is still sticking. Has anyone had this issue before and how did you fix it?

MoreUniversal III Tower
I have a uni III in great condition, but don’t have a tower for it and would love to restore it completely with the inclusion of a tower. Anyone have any ideas of where I could look? Or perhaps a loose tower hanging around for purchase? lol.
