Hello: Almost 3 years ago I wrote with some questions regarding the motorization of a Universal III I had acquired without the motor. Paul and others had thoughts to share on the matter, (much thanks for this input to all involved), but it was apparent that this would not be an easy task to accomplish. […]

Universal III-Rag stuck in gear
While cleaning our new Uni III, one of my students managed to get a rag caught in the drive cylinder gear. They wisely cut the motor off and unplugged the machine, but our attempts to The chain is very tight; I cannot find any wiggle room to get the rag out. I’m now trying to […]
MoreWear on rails / Carriage bearing adjustments
I have been methodically troubleshooting the irregular impression I get on my 15-21 and have since learned about wear on the rails. I am at a point where I’m wondering if I need to do something really serious or if the amount of wear isn’t a big deal and I can somehow adjust the bearings […]
MoreUni III Carriage slam
Ive had my Universal III for almost a year now and have been running some large editions on it. 99.9% of the time she runs perfectly, but occasionally upon returning to the feed table the carriage will slam home with a startling amount of force. Im talking once out of a few hundred cycles and […]
MoreAutomatic carriage stuck in print mode
Good Evening! I have recently come into possession of a Universal I Power Test Press with automatic cycling abilities. This is the first automatic cylinder press I’ve had experience with and I am finding there are some things I do not understand. When the cycle mode is on, the press does not go into “trip” […]
MoreSP-15 rear trip pin wearing ink drum belt?
My SP-15 is showing wear on the rear trip pin from the ink drum belt. Photo shows wear from both trip and print positions. The belt touches the trip pin. Is this expected? And if not, what’s the best way to adjust this? Additionally the trip arm had been touching the ink drum (wear from […]
MoreNyliners too big for SP-15?
Dave Seat discovered that both our SP-15 presses were missing the outer bolts that hold the outer nyliners in place. We ordered new from NA Graphics, along with nyliners, but the nyliners are too big; the neck is too long to put two on the shaft. Instead of going to the hassle of returning, etc., […]
MoreSP-20 inking problem
I’m printing a very large plate of a linear illustration. The poster size is 18×24 and the plate is almost that size. I’m using my SP-20. The problem I’m having is, right in the middle of the form, I’m not getting solid ink coverage. It’s almost exactly in the center. My rollers are only 4 […]
MoreSp-15 Slowdown
One of our SP-15 presses at UAFS has an oscillating cylinder that is slowing way down shortly after being inked. It doesn’t seem to matter what kind of ink (ie, stiff or loose); it’s as though the ink is too thick. This machine has had a motor replacement (posted a few years back on this […]
MoreAdjustable Bed Surprise
Here’s some lovely photos from Barbara Crocker of her 15-21 who writes “I had been having trouble with my press bed being high on one corner. Thanks to you, I decided to clean the wedges and it has definitely taken care of the bed issues….lubed the wedges and got it back together, much better without mouse […]
MoreFabricating Replacement SP-15 Impression Cylinder
I’m considering grabbing an SP-15 press but, like many presses out there, getting it into running order will require some TLC. The press bed, cylinder rack, bed bearers, under rails, gripper pedal, trip latch & rail along the bed, steel cabinet, and feed table all check out and seem to need nothing more than heavy […]
MoreTrip rack on 15-21
When in Print mode, my cylinder trip rack rides up the trip wedge and makes the carriage jump up right when the cam follower rolls off the top of the wedge. Is it possible to adjust this?
