This is a mighty old thread that was bumped.
For some reason I believe my old bike was always 126mm making things easier.
As I progressively moved from 2x5 to 2x6 to 2x7 gearing, I simply moved the washers and spacers around between the left and right side of the hub, and seemed to survive. I wasn't too good at dishing years ago, but a bit better now.
Anyway, no need for a new axle when all I needed to do was flip a spacer from one side to the other.
The last freewheel I ended up was a DNP Epoch 7 speed which was just a touch wider than other 7 speed freewheels, but I managed to squeeze a last touch of adjustment out of the axle. I think the company may have started machining for the back side overhang on at least some of their freewheels since that time.
Also, as mentioned above, if one changes the OLD by say 1mm, recenter the axle, and it may well be fine.
