Another vote for caution and avoidance when it comes to using the 2x72 to hone!

Is your Bader variable speed? If it is not, you will absolutely overheat the edge in a heartbeat. If it is, to avoid damaging the heat treatment you would have to run it so slowly that the advantage of using the grinder would be lost. Also, as TC mentioned, the direction of your drive would need to be reversed. I love my 2x72 and how versatile it is. But IMHO it is just the wrong tool for this job. There is a reason razor makers use their 2x72s to shape the blade but not to hone.

EDIT: just saw your grinder is in fact variable speed. But the other issues remain.
