Homebrew,
You shouldn't be doing that, the dropout spread is not correct. By 'forcing' a wider hub onto your frame, the dropouts will be at an angle to the hub flange. A good frame person will not only permanently widen the space between the dropouts, but also change the angle at this new spread so they remain parallel to the hub flange. This is especially needed for older dropouts that you move the wheel forward to remove, so the wheel is held in tightly and doesn't creep forward when mashing on the pedals in a low gear.
