Challenge 15MP oiling question
Hello All, I have a Challenge 15MP (similar to the Vandercook SP15). Not having an extensive manual for this particular press, I am not sure I’m finding all the appropriate oil ports to lube it correctly. Does anyone have a schematic showing proper oiling points for this press? If not, is there one for the […]
MoreChallenge 15MP carriage bearing adjustment
Hello all, I made the first adjustments to the lower two eccentrics on either side of the carriage today, gaining a much more even impression across the width of the bed. Special thanks to Gerald Lange, Fritz Klinke, and others for their very helpful posts/articles here on the Blog re: this topic. The remaining issue, […]
MoreSetting Impresion Bearings
Hello All, I’m having a grand old time trying to set the bearings on my Challenge 15mp and it’s been over two weeks of adjusting, proofing and re-adjusting. The main issue I’m finding is that my carriage shifts once the rear impression bearing comes in contact with the rail, causing the rollers to rise and […]
MoreCHALLENGE 21MP
Hi All, I am helping to restore her Challenge 21MP. It seems the inking rollers and assembly are missing. Maybe dutifully taken off the press after printing and forgotten about. The cores and rubber are not as much of a problem to replace as the gear and other metal parts that attach to the rollers. […]

MoreHelp with ink distribution roller Challenge 21MP
Hi folks! I’m hoping that your collective knowledge can help with a Ink Distribution Roller issue. I have a Challenger 21MP.

MoreChallenge 15MPC
I am reconditioning a 15MPC and am in need of an MPC manual or a pic of the impression Cylinder drive. I believe the parts are all there to reconnect except for the friction wheels (guessing) that ride the main drive shaft. Any help here would be greatly appreciated. Regards Steve
MorePatent Pages Premier
Terry Chouinard sent me this advertisement he saw in the BBS Specimen Book (No. 25) for a “Vandercook Gordon Press Vibrator.” He asked if Vandercook made any other equipment for production presses? Good question. After all, their presses were marketed as pre-press equipment. But nothing in the catalogs I’ve seen references anything like the Gordon […]
