I just got new rollers for my Vandy 215/4 and gave the parts on the roller frame, gears, etc a thorough cleaning. When i try to put the pin in the clutch block, it does not seem to want to go either way. What am I doing wrong? (BTW, ain’t them new rollers purty??)

Noise on Vandercook 215
This press is similar to a #4. I was trying to raise the form rollers (the lollipop showed them as being too low). I was able to raise the form rollers on the operator side, but not on the gear side. I suspected the form roller bearing bar had come loose (it has two bolts […]
MoreVandercook 215 Switch Replacement
The old switch fell back into the box. It was being held in place by a metal clip on the frame, shown here on the wood feed-board of the press. I could not get it to grab the switch, so I figured I would just replace it with a household switch, but am unclear about […]
MoreShudder 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 lead between the metal roller assembly and the bearing block of the rubber rollers (see […]
MoreUni 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 that face outward. Anyway, a few days ago, one of the rings came off the […]
MoreSP-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, in printing the oscillating roller squeals badly. Just started doing this today. Any thoughts? Thanks.
MoreSP-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. I cannot see any obstruction. Any help to a diagnosis appreciated.
MoreUni 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, which is mylar? I’m thinking of going back to a paper tympan also. Any thoughts?
MoreUni 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 it on, but it’s a rivet of some kind, so I cannot tighten it. But […]
MoreUniversal 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 not suitable for acetate; 2. the acetate is thinner than we usually use ( I […]
MoreUniversal 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. But the front roller knobs do not move at all. Wondering if there is a […]
MoreSP-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 bottom plate, the plate the motor sits on. I think this was so my machinist […]
