Meltiing the nylon out caused a little damage to the ailerons but it is repairable. Hopefully there is enough good wood inside to hold the hinges, the hinges were actually only in the balsa leading edge of the aileron, not too think there. You cannot melt all the plastic and epoxy out without damaging the inside of the structures. Maybe the dowel method would have been better but the taper of the ailerons would make it hard to do after they are covered. As it is I crack the sheeting on top of the aileron and will have to sand, seal and repaint it. Thanks again for all the help,
