Leverdue, thanks for the good information. Fortunately I do all my arrows the same and don't need to move the set-up. I could never imagine arrow building to be so satisfying (even though I'm not great at it yet).

Thanks for the help on the function of the screw on the nock holder. Will using this be responsible for my opposing vanes (not the cock down one, the other two) not being nice and 120° apart? I am still not quite sure how turning this screw will help you with clearance? Clearance of the fletches? I'm sorry I'm a bit slow, but very new to the terminology...

Thanks,

Greg
