I thought the fletching on the Bitzenberger was based on the clamp. Should have said that as I know degrees between Vanes are set on the unit.so is fletch clamp a 1 degree right offset, right helical, straight, left of the same or what?
The clamp is what designates the right or left orientation. You can get a left or right straight clamp to put left or right “offset fletching” on or you can get a left or right helical clamp to put on left or right “helical fletching”. The two adjustable knobs are there so you can make adjustments to get the vane or feather to make perfect contact along the arrow shaft to accommodate different size shafting. The one shown is a right wing “helical” clamp
Clear as mud eh !!!
