Don't laugh, but I've glued navels up before. You just spray a lot of tail adhesive on the off side, make a big sticky mess, and stick it to their belly. Then spray some more and smear the hair to seal it off. Just be careful to not get ahead of yourself or it can look funny. I have sent a few head through the ring like this quite successfully. Glued a friend's navel up on a heifer that always had her navel commented on and nothing was said. It works quite well.
