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 with it. This only seems to happen when we are in print, and it is still intermittent. As noted before, this press was neglected for years and has a LOT of grime built up. Paul cleaned the mechanism somewhat when he tuned up the press and we have kept it well oiled, too.
Have any other SP-15 users experienced this? Is it something that these presses all suffer from due to the design? I’m thinking of purchasing another SP-15 for our shop, and don’t want to have similar problems. I have used other SP-15’s and don’t recall this issue, so perhaps it is not a flaw that they all share.
Maybe it’s a combination of not so hot design made worse by grime. If it’s due to the grime, does that mean we will have to disassemble to clean? I seem to recall that is a nightmare job…
