RE: Question about Grayling Jig
There is a setscrew on the side of the knock dial that you need too lock into positison. This screw will allow a 15 degree variation, if it not screwed tight this will give you the play you are experiencing now.
Here is what the instructions say on line B.(Insert Nock Into Desired Position In The Knock Reciever(item B).Screw On The Knock Dial (F) Allows For A Fifteen Degree Variation And Should Be Locked Into Position
Before Any Glueing Is Started).
Once you get your dial isset towhere you want it lock down the set screw. Starting withthe cockfeather. Once you have this set where you want it tightenthe lock screwand you'll be all set .
This is what the screw at the base is for ..
Also do you have the instructions ?
I have a Grayling Jig and have had no problems with mine,once your all set you'll be happy with it , I have been pleased with mine..
Good luck Bill
