Greetings. I need to remove the safety roller, and perhaps the entire roller, on one of those extra-thin Illinois 12s movements. It needs a roller jewel and the safety roller crescent is spun about 20 degrees from the jewel location. I have tried using a lathe collet to turn the safety roller, but get no movement on it. Therefore it appears as if the roller will have to come off, taking the safety-roller with it. Someone's previous repair attempt on the roller jewel left a large amount of shellac underneath the balance arm, between it and the roller. I have soaked this off with denatured alcohol. The excess was probably there because there is so little space between the two in order to get the right amount of shellac in place. I'm thinking the only way to do it right, is to remove the roller table. So, in your experience, what roller-remover has the thinnest jaws to reach between small roller-table/balance-arm clearances? My duplex style's jaws don't quite make it. Many thanks.
