Default RE: Well...you boys were right...again.

Well we spun the arrows and their straigtness wasn't the problem in my opinion, they were pretty straight however I do think they are a bit underspined at 26 1/8" long and approx 67lbs draw on a GT 55/75. They were green label gold tip hunters (the same as I am shooting out to 60 yards with great accuracy). I know binary's are fairly tolerant of underspined arrows (more than other cams at least in my experience) however I felt he would benefit from a stiffer 340 spine since broadheads will be on these. If they were a field point only arrow for target or backyard practice I would have recommended staying with the 55/75's for $$$ sakes, but I strongly believe in proper spine when broadheads (especially fixed blades) are in question. Since no one has Gold Tips in stock right now we got him into Axis 340's from the shop and spun them all to find the straightest ones and set them aside for broadhead arrows. The ones that didn't spin so well (4 from the dozen) are going to be marked as field point only arrows. I am going to cut them to 27.5" long with 100 grain points and crank the bow up to 70lbs and according to OnTarget2 he should be spined just on the stiff side of perfect. I would rather see an arrow just a bit stiff on the chart than not stiff enough. 70 should feel pretty good too I would imagine since he picked up the smooth mods tonight before he met up with me and has more valley and less peak draw force than the fast mods he is used to.

After looking at the old arrows and while waiting for glue to dry on the new Axis arrows.......I looked at the tune of the Tribute. First of all, the rest was installed way too low by the original dealer to the point that broadheads were actually touching the shelf when at full draw. We raised the rest so the arrow was level with the berger holes in the riser when the rest was in the full up position. Then I checked centershot. I don't have one of the fancy lasers that Greg has........but I do have a golden key center shot gauge and used that to find true center shot. The bow had been setup with the rest probably 1/4" outside (rest too far left when looking from back of bow) of centershot. John showed me the paper tune holes he had shot before and they were all nock right matching up with where they should be for this centershot position. I adjusted to perfect centershot according to my gauge.

By time we did all this and got the new arrows fletched, it was pretty late and he had to head home for the long drive. I think he is still driving as I type this. We are planning to meet up on Friday after I get out of my 9-5 job and head to the range to check form, shot execution, and then walkback tune then papertune as well to triple check centershot as well. I am also going to tie in nock points on the bow as the original shop used brass nocksets that may or may not be at proper distance from eachother for these nocks without pinching......I suspect there is a nock pinch issue as well going on here. We are also going to check 2nd and 3rd Axis on the site at that point to make sure everything is in check. We will use a level, a vise, and a plumbob for 2nd and 3rd axis. We will update then more so everyone can hopefully see how we did this and maybe be able to do this at home on their own.
