At this point a replacement set of hands is probably your best bet. In some cases, you can do some repairs. If the tube was enlarged during the removal process, a staking set can help close the tube back down so that it actually grabs the pinion. If the tube has separated from the hand, that is also something that can be repaired, but it is quite a skilled repair job and not for the faint of heart. Freddy's post above shows a great fix for you if you are up for it.
Good luck!
