I'm going to take a different slant on the problem : Tiger dude you said in your first post that your servo was buzzing when you activated the controls, that's not a good thing and to me it indicates that you are activating your controls farther then they were designed to go causing the stab to flex. Try readjusting your control linkages so there is No buzzing and No binding .
If you still think you have a hinge problem here's somthing I have done in the past. If you have a small trim iron (I've used a small soldering iron ). Try very carefully running the iron along the hing line to loosen the excess glue, then peal it out with a knife or something. Don't increase the gap, the less the better as long as it doesn't bind. ENJOY !!! RED
