While I was bottling my last batch, I felt unusual resistance, stopped, and saw the lug ends of the metal legs (not the handles) were misaligned and displaced where they grip into the ring at the bottom. The main 'plunger' was also well off to one side. My dad (a retired production engineer; his dad a toolmaker) hasn't yet found a simple fix, though nothing appears to have snapped. Not easy to get everything back where it should be, apparently, and he's already replaced a couple of rivets in the process. I don't have it to post a pic at the moment, but I wonder if anyone has had a similar issue or knows them at all. Worth a shot!
(Here's a pic of one similar)
