Hello – Ready for my daily SP-20 question? I truly appreciate all the shared knowledge and help I’ve received along the way. Anyway, a few days ago I noticed that I can wiggle the cylinder back and forth with out the cylinder moving down the bed. There is 1/16th to 1/8th of play before the […]

SP25 gripper problem
The SP25 at our school press (Virginia Commonwealth University – Bowe House Press) is experiencing difficulty when trying to raise the grippers. We tried oiling the exterior items that are attached – the X-22516 Gripper Shaft, but this did not help. This problem began in the past two weeks, before there was no indication of […]
MoreSP-20 Motor (Shaft Key) and Ink Drum Removal
Hello – I removed the ink drum chain this morning and noticed that there is quite a bit of movement in the gear that comes out of the motor. Is this normal? Or do I need to push the pin (that is sticking out) further in? Here is a video. I am sorry about the […]
MoreSP-20 Wash-up Blade
Hello – Has anyone found a replacement source for wash-up blades? Any leads or even blade specs would be greatly appreciated!
MoreSP-15 Motor Belt
The oscillating roller on one of our SP-15 presses began hesitating this week, out of the blue, just like the video posted in January. For that poster, it seemed the solution was a new belt. However, both the motor and belt on our press are relatively new, so I figured that might not be the […]
MoreSP-20 Taper Pin Specs for Handle
Hello – Alas, the taper pin for the handle of my newly acquired SP-20 disappeared during transit. Can anyone provide any specs? It looks like I could order one from Grainger or maybe NA Graphics has originals? Thanks!
MoreSP-15 retaining screw
Greetings! I’m looking for advice regarding a retaining screw that has partially worked its way out of the bearing block on the operator side of the front form roller on our SP-15. Any suggestions for best practices in terms of returning the screw to its proper location? It doesn’t seem to want to budge… in […]
MoreNew info in SP-15 roller hesitation problem
Hey Everybody, It seemed like this was going to be a workable problem, but now in actuality it has taken a turn for the worse. Today we printed a navy ink with no problem, then washed up and put PMS 874 (gold metallic) on the press. Very quickly things went down hill. I am attaching […]
MoreSP 15 vibrator latch
The “catch” that holds the “vibrator assembly” isn’t doing a very good job of securing the vibrator assembly in the “up” position. I can’t tell whether its spring loaded to keep the pressure on or whether gravity is suppose to do the job. Its dirty up in there and i will clean it, but if […]
MoreSP-15 rollers hesitating
Right before the holidays I was finishing up a print job and noticed the the rollers didn’t want to turn with each other anymore. I thought it was the ink drying as a result of the heater blowing close to the press area and didn’t think about it again. After being off for a few […]
MoreSP 15 Rollers Condition
I bought a SP15 a couple of years ago. The rollers were/are clean and seem to work fine, but they are shiny and quite hard. However, after reading a recent post on Briarpress about cleaning rollers I wonder if mine are glazed and need to be deglazed (or possibly recovered). Certainly, the rollers are not […]
MoreSP-15 roller grinding sound (pictures and video)
I am having trouble fixing this sound. I believe it is being caused by the gear on the inner form roller when it travels over the form roller rack teeth. See the video to hear the sound. This happens in trip or print. Vandercook SP-15 grinding sound (YouTube) Here is a photo of the gear […]
