I have questions regarding skate holder adjustments. I have an old Blademaster machine and use the Wissota 3D holder. I have to make adjustments on every skate to get even edges (checked using the Blademaster BR100). This is true for two skates of the same pair. Often I will have a skate with an even front part of the blade but uneven back or vice versa. Is it typical to have to adjust the holder for every skate? Also, when making adjustments to get even edges should I adjust the back dial at all or just the front two on the holder. I have checked for level and squareness on the holder a few times.
