...I don't know what your physical size is that merely, with a crescent wrench, you can remove a freewheel....but I need a lot more leverage. A 'breaker' bar at least the diameter of the wheel...30 inches or so...that if the nut could be seated in the center of the bar, I could push from one end, pull from the other...and control the effort with much more certainty so that no damage would be done to either the tool or the seat on the wheel where it grabs the nut...

I want the driver interface with the nut to be at the center of the bar so that it will be much safer to apply the leverage, pushing and pulling from opposite ends of the bar at the same time.

Sears and Home Depot don't have anything that allows me to do that....I'm trying to contact a local Snap-On guy but haven't been able to get him to respond as yet...'n their web site doesn't lead me to graphical images that show me what I want...
