Britt at Banshee Press continues to have a problem with her Universal I Power. In a comment to the previous post, I asked her to check for a loose and/or warped trip rack (X-14854). It’s worth noting that Vandercook made an engineering change to a more rigid part (X-21774 ), first used on press with serial number 21857. Fortunately, Britt’s press has a higher number and see seems to think this is not the problem.
I asked her to send me a new video showing the backside of the press (at right). One can see that the clunk happens just as the cam follower/bearing (X-2726) contacts the bottom of the trip wedge (flipper). The problem is likely that this linkage is grimy and/or loose. Inside the cabinet one can see the end of the linkage. Look for a sliding flat bar and set screws.
If you can’t solve this, I will see a Universal I in Chicago next week.
