[ATTACH=CONFIG]577150[/ATTACH]I am still a bit hazy on your question, NZ. Are you talking about the little set screw with the flat blade slot or the knurled knob. Wait, if you are bending your screwdriver, you must be talking about the little set screw. Penetrating oil . Try to get it to turn the other direction a few degrees to break it loose. Heat. I'd say to make sure your screwdriver fits, but if you have a good enough grip to be torqueing the screwdriver that isn't likely the problem. In drastic cases. you may need to put the screwdriver in place and tap in with a hammer like you are using a nail punch. Try other things first though and I should say, "You are remembering lefty loosey aren't you?"
