Hi all, I’m the new caretaker of an SP 20 (serial 23442). I’ve been investigating a carriage jam issue and have found that the trip assembly on the non-operator side of the carriage (X-21755) is sitting much lower than on the operator side. Because of this, the rogue trip arm has been scraping against the […]

SP-15 Trip issue
A student emailed me last night (I got the email this morning) that one of our SP-15s had stopped working in trip. The cylinder hits part of the trip mechanism and will not move. The cylinder moves fine in print. I cannot see any obstruction. Any help to a diagnosis appreciated.
MoreSP15 spare part, broken trip spring
I was levelling my press yesterday (SP15) and found a ‘spare part’ (?) lying beneath the press. It has the same greyish colouration of the press and looks like it could be vital? The press is still printing, though might prefer to have the piece if indeed it belongs somewhere? Is it part of […]
MoreSP-15 Trip Spring Question
Yesterday when printing I noticed that the usual sound of the trip springs on my SP-15 seemed different/quieter. Upon examining, I found that the spring on the operator’s side is no longer fitting snugly under what is referred to as “Dowel B” on sheet #302 “SP Series Replacement Trip Spring” diagram that Paul has posted […]
MoreSP-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 […]
MoreRestoring an SP-20 (i.e. hunting for parts)
Hello all – – I had the great fortune of saving an SP20 from the scrapyard earlier this Spring. However, it was not quite as complete as I remembered it being when I first found it last Fall. Someone clearly attempted to dismantle it sometime in its history, then abandoned it, and the only old […]
MoreSP-15 won’t trip
I’m having some trouble with my press and I’m wondering if someone out there can help me diagnose the problem. First off, I have a Vandercook SP-15. I purchased it a while ago and just recently got it up and running. I was able to print on it for about 150 impressions when it became […]
MoreSP 15 Trip Spring-variations?
My SP 15 seemed difficult to get into Trip/Print so, after researching similar posts on this site I drew the conclusion that I was missing the flat spring (x23790) and upon inspection, this seemed to be the case. However, now that I have the springs, I am looking at the trip arm assembly and it […]
MoreSP 15 Carriage Side Panel removal
Hello all, I recently purchased an SP 15 and am finally getting around to cleaning/restoring it to printing condition. In the process I came across what appears to be a broken trip spring. Since the gears and trip mechanisms were an inky, greasy disaster I decided to pull the side plates and give it a […]
