Don't know how to ask/don't know what I want.

I cut a slot in the end of the jack handle so I can fit it over the end of the valve and and open and close the valve by rotating the handle.
Several of the floor jacks I've used over the years (maybe ALL of them) have the valve right next to the socket the jack handle fits into to pump it up.
Simple, if not very elegant!
I think I've been overcomplicating a cheese sandwich all afternoon.
