I have about 2 dozen Gunline checkering handles and loose cutters. I have tried many times to install the "spirol pins" that gunline supplies with the cutters but have not suceeded even once. I tried to drive them in and I tried to press them in but all I have done is smash the pins. Does anyone know how to do this? The pins seem to be much too large for the holes in the handles and cutters. I know there are two sizes of pins but I am using the pins that came with the cutters.
