Bow tuning update

I have been reading and watching some articles about nocking point height, d-loop length, peep height etc, by Alistair Whittingham and John Dudley.

One of the things I suffer from is holding low on the target, and the sight bobbing up and down, which invariable causes me to fight it, and hence introduces tension into the shot. Up until now, I have put this down to me alone. I have even thought it could be a mild form of target panic.

So I read and acted upon a couple of things. First, I am happy that my draw length is OK, so that has remained untouched. But I have played with the peep sight height, nocking point height and d-loop length.

The peep sight height was easy. I moved it down just a mm or so to get a more comfortable view of the scope, especially at the longer distances. In fact all distances feel a little more comfortable.

Next was the d-loop length. This has been shortened by maybe 2 to 3mm. The suggestion was, making the d-loop shorter (if your DL looks OK), would help lock in the drawing arm at anchor. My d-loop was a little long and it caused the arm to floating around a bit, and most likely causing small movements that meant the bow bobbed up and down.

The final and probably most compelling change is the nocking point height, or position, on the string. This is in effect good old fashioned tiller tuning, but instead of leaving an uneven tiller (I shoot a single cam bow, so the tiller is uneven anyway, so in this case, it would mean the limb bolts simply being unwound a different number of turns), the position of the nock point is moved up and down until the aim steadies. As it turns out, my nocking point was about 3mm too high, and after some experimentation, the aim has locked into place. This has also meant the pressure on the bow hand has changed, moving it lower towards the wrist joint, so the pressure of the bow is directly over the bone. Before, it was a little high in the grip. All of these changes together have had a remarkable affect.

For the first time in a long time my aim (when the form is correct) is much steadier, where as before I seemed to always be fighting it. I have only moved things by a couple of mm, but it has been worth the effort.
