Vandercook 219 Trip lever assembly

Vandercook 219 New Style infrequently does not stay in trip mode on return to feed board, the operator must very slowly return the cylinder to the feedboard. Examining the ‘Cylinder Carriage’ spec sheet on the owner’s manual suggests that the ‘ (X-2884) Connecting Rod Assembly’ with its 8 ‘(X-3602) set screw(s) with lock washer and …

Challenge 15MP been in storage for 40 years

I have recently lucked onto a Challenge 15MP that is lightly used and been stored in a dry building for 40 years.  It has some light surface rust but nothing that fine steel wool can’t take care of.  Everything moves and ball bearings seem to be fine. Here’s my question: can I adequately clean and …

Desperately seeking a solution to a mystery (Cylinder Jamming)

I have a Vandercook 219. Not sure but I think NS (1957). It prints like a dream, or did until this afternoon.

No. 4 Print/Trip Assembly

I just started working with a friend’s No. 4 press. It prints great and seems like a really solid machine. The machinery used to lower the impression cylinder from trip to print during the print stroke then back up to trip for the return to the feed table seems very different compared to the SP …

About to embark on cylinder carriage adjustment-Universal III AB

The symptom: The top of the bed has less impression.

219 OS eccentric and rail questions

Hello- I’ve posted on Briar Press regarding some inking problems I was having with my 219 OS and have emailed/spoken with a few of you about these problems, but I have some additional questions that I thought best asked here. Currently, the carriage seems absurdly tight and heavy. At some point earlier it felt heavy, …

SP-15 Cylinder Carriage Bearings Issues

I undertook the arduous task of adjusting the 6 cylinder carriage bearings on my SP15, after still experiencing uneven inking and impression with newly recovered rollers. Thanks especially to Gerald’s comprehensive “Adjusting Cylinder Carriage Bearings” article, without which I never would have undertaken the ordeal: Adjusting Cylinder Carriage Bearings … And with Fritz’s recently found …
