2 Basic Tune Questions..

Whitehorn · 10-22-2007, 10:47 AM

1. I have heard that you are supposed to set the rest height so that the bottom of the arrow is vertically inline with the centre of the threaded hole (rest attachment) and I have been told that the centre of the arrow should be aligned with the centre of the threaded hole.. Not sure which is correct..

Also:

2. When setting the knock position, what is the reason why the knock should be 1/4" higher than the pefect horizontalposition? Is this to accommodate the knock? Or is there another reason..

Thank you very much, just learning.. Used to get my archery centre to tune my bow, but I am now wanting to do it..

Cheers.

I tend to follow this thread and have been doing so for many years.

This is a good starting point for setting nock height. Actual nock height is going to vary depending on your individual setup. Such issues as cam style, rest tension/style, arrow spine, etc... are all going to play a part.

Thanks PABowhunter..

Just to clarify, centre of the arrow in-line with the centre of the threaded hole.. Thanks.

Yes, your arrow shaft should pass squarely over the rest mounting hole.

On a few rare occasions I have had to set the arrow higher but only because of a lack of fletching clearance. That should not be an issue with any of the modern compound bows.

Hoyt bows with fall away rests often tend to shoot well if the bottom of the arrow is about centered with the Berger hole. With other rests, though, or other bows, middle of the arrow going right across the middle of the hole is a good starting place. I also like to start with the center of the arrow about .780 from the shelf, as a good starting place for horizontal adjustment. I am not sure as to the exact reason for the recommended nocking point being a little above square; but I have always had to be a little above this point to get the bow to tune properly.
