Hi everyone,
I have gone through several Ferrari corkers. They perform well for the first few thousand bottles then tolerances loosen up and I start getting corks with shaved-off edges and other trouble. The exact cause of this has bugged me for years and I think I have finally figured it out. I wanted to share with the group.
I just got a new corker. I noticed that the compressed jaws give a nice round profile, see pic below.'
My older corker, on the other hand, has a kind of lopsided profile, see below
This lopsidedness comes about because there is a bit of play in the mechanism where I am pointing with the Sharpie. There is no similar play in the new Ferrari. This profile lopsidedness plays havoc when you press the cork into the bottle. The edge of the cork along the longer dimension hits the mouth of the bottle and shears off or just makes the cork really difficult to insert. You need a nice round profile like in the first pic.
My solution is to add some shims. See pic below.
These are mild steel 0.75 mm sheets I slid into place. They take up the play and force the jaws into a round profile again.
Another modification I think might be helpful to others is attaching a plastic container to the side of the corker for easy/fast access to corks. This saves a lot of time when you are corking hundreds/thousands of bottles.
Putting this out there for the archives!
