Shudder In Vandy 215 (aka 4) Oscillator
Lately my Vandy 215 oscillator has a shudder as it travels back and forth. It actually seems to be stocking to the inked up rubber rollers below. I was able to stop the chatter by adding a small piece of
Uni III roller bearer issue?
Looks like when new rollers were put on the press, two of the roller height adjustment mechanisms were put on backward, so that the locking nut faces the wrong way. I assume they should face inward, but we have two
SP-15 Squeal
Got a bad squeal on the SP-15. Can’t figure out where the noise is coming from. Suspect that the back roller core is defective and the bearer is not holding it correctly. I think we need a new roller/core. Anyway,
SP-15 Trip issue
A student emailed me last night (I got the email this morning) that one of our SP-15s had stopped working in trip. The cylinder hits part of the trip mechanism and will not move. The cylinder moves fine in print.
Uni III Draw Sheets and Packing?
I wrote to NA Graphics earlier today to order some Uni III packing, but have not heard anything. We need something right away, and I’m wondering if anyone can recommend paper that we can use for packing under the tympan,
Uni 3 Roller Bracket
I’m not sure of the actual part name. See photo. It’s a bracket that goes on the bar that raises or lowers the rollers. I’m wondering if it should be loose or fixed? I thought there was a screw holding
Universal III Tympan Issues
We have successfully used mylar/acetate tympan on our SP-15s for years, but when we tried one on the Uni III, it keeps slipping. There could be multiple causes: 1. The mechanism for holding the tympan on the Uni II is
Universal III Roller Height
I need to adjust the roller height on our Universal III and am wondering if there is a trick to it. I was able to turn the knobs on the back rollers slightly, enough to get to a good height.
SP-15 Belt is loose again!
Seems like we just replaced the V-belt on our SP-15, the one with the newer Baldor motor. It is already loose again. The last time we had belt issues, Lad Boyle wrote about a process he had for removing the
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;
Nyliners 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
Sp-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
