I'd like to see the tap wrench that goes with it.


This being a coarse thread, I would think that the wrench would be
operated by 2 people and should be 2 meters long.

I thought it looked fine for 12". The immediate thought I had was why
use a tap? The next one was probably it's used for field repair. What
a bear to handle. Whatever you're working on would have to be
vertical. I can't imagine trying to use that thing horizontally.
