Our newly acquired SP-15 has a very loud motor. Not sure if this is normal. We have a second SP-15 that is also loud, but not as bad as the newer one. I sometimes have to shout for my students to hear me. I received several suggestions to check/add oil, and we did that, but […]

SP-15 Trip still giving fits
Last month, I posted a query about our SP-15 at UA Fort Smith, in which the trip eccentric release mechanism in the cylinder was crashing into the trip release button on the operator’s upon return to home. (see the original post https://vandercookpress.info/vanderblog/2011/02/sp-15-carriage-problem/#comments). This has begun happening again, despite oiling the press every time we print […]
MoreMore Tag215 Vibrator Issues
The vibrator has been pausing and jumping, so last night I took it apart to see if anything was broken on the crescent or worm gear. Didn’t find any problems, but I cleaned everything and greased it thoroughly before reassembly. Tried it this morning with no ink and it still hesitates at some points in […]
MoreMore TagSP-15 Rail Wiper & Motor Issues
Our SP-15 (#22182) at UA Fort Smith is missing the nylon wiper (X-20758) that apparently cleans the rails on both sides of the press. Looks like these were replaced at some point with a couple of pieces of thin metal. The other day, on the non-operator side, these bits of metal shifted and on the […]
MoreMore TagSP-15 carriage problem
We have recently begun having an intermittent problem with our SP-15. After printing, when the cylinder is returning to home position, it hits some obstruction about 12″ away from the feed board that causes a jolt and a significant bang. It doesn’t do this all the time (maybe 1 in every 4-5 print passes), and […]
MoreMore TagSP-15 Trip/Print blocked
We’ve been working on cleaning up our SP-15 in the new UAFS Letterpress Shop. I took the motor cover off to clean a large pile of old ink next to the drum roller. After putting everything back in place, now the Trip/Print lever is stuck in PRINT. Doesn’t matter if the cylinder is in home […]
MoreMore TagSP-15 slipping tympan issue?
I’m teaching a workshop at Northern Kentucky University where they have an SP-15. It’s been many years since I have used this press. We’re having a problem with the tympan paper coming undone at the back. The ratchet that holds the tightening bar in place appears to me to be set backwards, at least it […]
MoreMore Tag215/4 Ink Rollers Dropping
I have had a continuous problem with the Vandercook 215 form rollers dropping down too low due to the hex bolts working themselves loose. We tighten these by hand because with a wrench, they get too tight and the rollers won’t turn freely. Is this an indication that there is something wrong with the bearing […]
MoreMore Tag215 Inking Roller Gear Issue
I have had some inking issues today. Some passes were ok, while in other passes, inking of the type on the form was uneven. I noticed that the back ink roller, the one that hits the drum, was having trouble with its gear/clutch not aligning properly on most passes (see photo). The front roller gears […]
MoreMore TagProblem with 215/4 Motor
The motor on my 215 just started stalling in the middle of today’s run. I had switched off the motor during a pause in printing, and when I switched it back on again, it hummed but did not move. I was able to get it moving again by physically moving the belt from the motor […]
MoreMore Tag“Broken” Switch on 215
During my recent move to Arkansas, apparently the switch on my Vandy 215 was pushed in from the frame, separating it from the metal housing bracket that holds it in place. Nothing is actually broken or chipped, but just separated. It looks like the housing is meant to be crimped to clamp onto the plastic […]
MoreMore TagWorm Gear Fixed!
A few weeks back, I wrote about a worm gear with a blunted point that was causing my oscillating roller to stop during it’s run back and forth. I tried filing the point down myself, and while I was able to get it smooth, I was not able to make a nice, sharp point. Last […]
