Trying to mount a front wheel on a bike that had none.

It had and was attempting to mount a quick release axle hub. Problem is, only 3.5 millimeters from the locknut to the end of the axle.

When mounted in the fork and compressed with quill, the axle only extends into about half of the dropout which is 5.8 mm thick.

Basically, what I am seeing is that only 3.5 mm of the axle that extends into about 3/4 of the dropout is bearing all the weight/stress.

Is that safe?
