Hi there. I am getting ready to dope another model here and that model has doped on hinges. I did this a few years ago when I wanted to start using dope. Fast forward to today. I am looking at my 'over and under' cloth hinges on the elevator and am not happy with them. I would like to remove the hinges and install sewn figure 8 hinges instead. The model is a 1/2a White Lightening with only the hinges doped, and the rest is bare balsa(no finishing has started yet). Is there any chance I could remove them without doing any damage? If so, what could I use. Thank you.
