I've done it more times with the bike upside down than I've ever done on a workstand. Works just fine, if a bit unsteady. I've also hung the bike from the saddle nose on a tree limb for a trailside repair. At home I don't have a proper workstand but I put a fold-down bike hanger in the backyard on one of the patio posts and that works just fine. Not as nice as a proper workstand but it gets the job done.
