Revised. I’ve recently refurbished a No. 4. When the roller carriage is in contact with the ink drum (hence the form roller clutch is engaged), there’s an awful squeaking sound. The front rider roller does roll, and the oscillating roller seems sort of sluggish. It’s difficult to gauge where the sound is coming from, but […]

Polishing drums on a SP-15
So I’m rehabbing my SP-15 currently. The rollers melted a long time ago, and the printer has been sitting in a garage for 20 years. There was some light rust and goop on most surfaces that I was able to remove. I followed the advice here and removed a lot of the rust with WD-40 […]
MoreMore TagRider roller frame
Hello guys —Happy holidays! I installed a long lost taper pin for the rider rollers shaft on my no.4 and realized that the MR-113 Tie Rods where the M-123 Rider Rollers go, are definitely twisted or bent so they make the installation of the pin a very tight fit and makes the frame sit twisted […]
MoreMore TagNew 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 […]

MoreMore TagInk Drum, oscillator and rider rollers
Hello everyone. Could someone please tell me what could be causing this uneven spread of ink on the ink drum? Could it be the press leveling? I’m not sure it is 100% level. I’m also attaching some photos of my refinished oscillator and rider rollers. I think they definitely improved the inking, I didn’t refinish […]
MoreMore TagSticky, tight, rider roller on 4T
I had the wooden bearings in the rider roller of my 4T replaced a couple months ago after the old ones disintegrated. Everything was working fine until recently when I noticed that every time I drop my rollers to ink up (with the motor turned on) the top frame assembly begins squeaking and then slows […]
MoreMore TagMachining a metal rider roller for SP-15
I got an SP-15 press with a missing rider roller. I purchased the brass end pieces from NA Graphics, and am about to go to my location machine shop and have the roller made, bringing with me a borrowed roller from another SP-15. Does anyone have any suggestions or advice? Is there a national company […]
MoreMore TagRider Roller on SP15
Hello All, I’m working on cleaning up an SP15 that hasn’t been touched in maybe 30 years. I have all the rollers lubricated and in their right places (as far as I can tell) but when rolling the carriage down the press bed, the rider roller isn’t moving. It almost seems as though it’s a […]
