In this thrilling episode!!! I learn some stuff. Some success is achieved and more puzzlement is created.
Ok. Spent the morning in the garage with the paper tuning box. Tried using deodorant to check for contact but the results were inconclusive. Need to order the spray. Tried the thicker rest but no obvious differences so went back to the mid thickness. Haven't tried taping the blade yet as I only had sellotape. Insulating tape has gone walkabout.
After a bunch of random results (good to tail up), eventually I got fed up and moved the rest upwards by a large amount. The principle being to swap the tail high for a tail low result and then work back down. However, it actually produced a good result. Several ends later I was still getting random results. Not massively wrong but not bullet holes either. Then I was convinced that my sight dropped on the paper at release so I swapped to a thumb trigger release (instead of the hinge). No risk of punching when aiming at a blank piece of paper. The next nine arrows produced at least six bullet holes and three with a slight tail left (could be the arrow).
So, Top Tech Tip - use a trigger release unless you are absolutely sure of your hinge technique.
The upshot of all this is that my sight pin is now almost bang on the bow centre as judged by aligning string with stabiliser holes. However, the arrow is pointing quite a long way to the right when compared in the same way. I haven't checked to see if the cam spacing puts the string at limb centre yet. I also haven't shot with the string away from the face to eliminate potential sideways oscillation caused by face pressure. My 2016s are probably a little underspined, should probably set up the 3-39 ACCs instead but, as far as I am aware, using a release aid and no button should prevent the
recurve type left/right issues of arrow spine.
