This is the tool I made:
http://www.os2.dhs.org/
That a piece of 5/8" all-thread, with nuts brazed on so they can't slip. Well, the nuts didn't slip, but the tool couldn't hold the cup tight enough to move it, even with an 18" wrench and a bench-mounted vise. So cut notches in a large washer to match the notches on the cup, brazed steel "teeth" into the notches to grab the cup, and brazed that on to the outer nut. But then the teeth tore out of the washer without the cup even budging.
If I had a TIG welder I'd try welding a lever directly on to the cup itself, as suggested.
