The RPM project
« on: February 12, 2013, 12:31:15 AM »
So there are a number of strange things with the press.  The last setup on the press before I owned it was terrible.  The carousel doesn't come up far enough.  You can see the old grease line and it is about 1" shy of where it used to table up to.  So all the heads are bottomed out on the off contact and the platens are maxed out to the top to try and make the press printable.  It works OK, but if the table came all the way up, my problems would be solved, that's for sure.

Any ideas on this one?  The off contact itself isn't working, so the problem might be there.  Or it might be in the valve that controls the left cylinder, that is leaking like hell in the down position.  It has been leaking for a while I guess and it has to be covered with oil inside because there are puddles under it.

It's strange.  I have an email into Rick and one of his techs, I sent it tonight, so we'll see what I hear tomorrow.  I am sure it will involve parts, just hopefully not the expensive ones.

This is a prime example of what happens when you don't train people properly and they have zero regard for equipment.

Not surprised considering where it came from

Yeah, i also wonder who moved it before.  They set it up with over 1/2" off contact.  Also, it looks like they pressed the membrane switches as hard as possible on head 1.

I got a good deal on it and I can fix it up, if I paid what a press in good condition was worth, I would be disappointed.

I am attaching a pic of the center shaft with the carousel up.  You can see it's not as high as it should be.

I think the culprit will be in the central off contact assembly.  I should probably just order a new one and be done with it...I think it's missing some parts.  Usually manufacturers don't put bolts on something without a nut on the other end.

I'd say you're missing a part that's about an inch tall!  ;D

UPDATE!!!  I disassembled the off contact to see what was up, my main goal was to gain an understanding of how it works.  It's so amazingly simple it's crazy.  I also wanted to clean it from top to bottom.

It's cleaned, re-greased, and installed and working like a charm.  The tables go up to where they are supposed to now, Now I get the job of resetting all of the head off contacts.  Yeah, I take it.  This should put the platens in the right spot on the arms and I can back off the squeegee adjustment.  This feels great.

I had this exact problem with a Vindicator install in NH a few ys back. Seems like there might be a common denominator but in all fairness should keep my mouth shut.
