Lol! Sorry guys, should have been more clear. I understand the concept of offset, and how you want a balance between solid base/shaft contact and vane offset/twist, I'm just wondering where the degree standards came about? What is 2 degrees? How do you know it's 2 degrees? Like I said, I'm fletching RH, and I've already got my new jig set up with good fletch contact. This question is more or less out of curiousity. Did somebody just pull these degree numbers out of their you know what, or can you really calculate what 2-3 degress offset truly is?
For instance...the new Bohning jig that was at ATA this year is allows for perfect 3 degree offset on all blazer vanes. How are the degrees calculated?
