In common parlance, the term jet engine loosely refers

So, yeah, in the strict technical sense you are correct: Any reaction
motor that discharges a jet of exhaust can be called a jet. But I'm
going to claim the broad low ground of "common parlance."

As late as the mid-60s, it was still common parlance to refer to
"turbojet" engines, to distinguish them from other forms of jet
propulsion (thus cleverly revealing that I'm old enough to remember).
As a completely random aside, for those who might be interested in a
key but now nearly forgotten figure in the history of both Jet
Propulsion Labs and Aerojet, look up Jack Parsons in your favorite
search engine. He was the quintessential "rocket scientist"...


Anyhow, your winch project with Bob Korves is looking good!

Let me know if you need some occasional welding or fabrication. If
you've got one Bob K. on your project, two is going to be better,
right?

We've hit that point where we're 90% done, and the remaining 10% is
taking as long as the rest. Thanks for the offer!
