I have been using the Arten Tolgate jig for the last year and it is quick, simple and sturdy and, despite past comments on the magnet I have no problem with this but, and this is the purpose of this thread, I recently noticed that the fletchings on my lad's arrows were note evenly spaced arond the arrow.

On looking further I have fund this with many of his arrows so I did a little test on the jig using some card on a shaft, marking the card at each position and then joining the sides. What I found to my great surprise was an isosceles triangle when what I was expecting was an equilateral one.

My son has been experiencing clearance problems and we have tried all manner of tweaks to the bow, what I now suspect is the angle of the fletchings around the shaft.

Does anyone have any experience of this?
Do any Tolgate owners see the same effect?
If anyone from Arten is reading... Is this normal? (Please understand I am not knocking Arten as I think they are a good company)

Anyone?
