The problem in this instance was that the QR was simply too loose and ground away at the dropout material. This was user error and would have been the case with any sort of QR.
that wear can also occur from using the QR as a Wingnut lever...steel ones chew up the dropouts faster, in that case...
the axle is now flush to the dropout's outer face... the wear will be found in the top of the dropout too..
getting the dropout welded up, when reworking it to fit properly, is a very highly skilled task that most people should not attempt, nor could do well.
the difference between "Level" and too far is a matter of two or three strokes with a file.
i re-dress fork dropouts on brand new Walmart bikes fairly often... the workers are instructed to use off-center wheels to "compensate" for the leveling errors, which actually exacerbates the problems.
