For a lot less money, you could buy a 3/4" drive ratchet handle (or breaker
bar) and the appropriate size socket in 3/4" drive. Assuming you have a
tool made to hold the companion flange. Two pieces of pipe about three feet
long (pair of cheaters) would then allow you to remove the nut without
exceeding a gentlemanly level of effort!
