We bought this wine bottle opener for $2 at a yard sale, not noticing that
it was missing a part. It has never been used. It is missing the part
that is at the top of the 3 piece cylindrical shaped thing right under the
handle. What is sticking up now is a threaded end. It looks like
standard threads, 1/2" dia.

*Whose* standard? The US seems to use 13 TPI for 1/2", while
the UK seems to use 12 TPI.

And are you sure that the threads aren't an ACME thread instead
of a usual 60 degree thread?

If I could describe the missing nut, it would look like a small cup with
threads inside.

Does anyone have any idea where I might find such an item? If it came to
it, I could make one by getting a nut, welding a top on it, and grinding
it down to round. But the real deal would be better.

Perhaps an acorn nut -- used to cap the threads on a shaft
coming through a handwheel so you don't gouge your hand on the threads.

Note that they have a hex for a wrench below the dome.

MSC and other vendors have them. Usually nickel plated for
appearance. The only problem may be the minimum quantity.

Good Luck,
DoN.
