Great way to destroy your axle(just like you did :P). If you have bearing separator AND bearing puller then just simply hook puler to the separator. If you have only separator just clamp it like you did and then use 2 screws, and ~10mm steel bar to push the axle. Separator have 2 vertical holes, one on each side - use as large screws as possible. You need to drill 2 holes in steel bar in correct distance to push that axle. If you don't have separator / puller you can use long socket and hammer, but please use at least copper coin on top of axle to not destroy it like on this video.
