Bill:

You said:
There is a bone in the human skull, the lower part of the nasal septum, called the "vomer" which seems to be ultimately from the same root as vomit. It was also a Late Latin word for ploughshare. I can't quite figure out why.

Well, there isn't any connection, which is probably why you cannot figure it out.

Vomer is a noun, deriving directly from the latin word vomer, a ploughshare.

Vomit as a verb derives from vomo, vomere, vomiti, vomitus, to Bushusuru.

It's just cooincidence, I believe, that they start with the same first three letters. But there are a LOT of words like that, doncha know?
