Also I filmed the entire process and will post a long "how-to" covering material sourcing, to gluing, shaping, tillering for equal limb timing, finishing, and tuning the arrow shafts to the bow.
Built my First Bow
So I cut the shelf in. So far, the same exact arrows fly better (no change in spine needed), and I bought some 350 spine Victory VForce HV arrows to try out. They shot nearly perfect with 250 grain tips bare shaft. One concern is that they are thinner walled than advertised. The spec says .287OD and 6.8gpi, but my measurements show .281OD and 6.0gpi. On the bright side, I can shoot a 550 grain arrow at 30% FOC no problem. I could also shoot a 600 grain arrow at 34% FOC by using 300 grain points. My old GT Traditional 400's weigh the same with 200 grain points, and would mean I should be able to shoot either or without much difference in trajectory, at least at hunting ranges.
I also ordered some Point Oxford Cedar shafts to use for stumping and small game hunting. I'll spiral flu-flu them, and adjust length and point weight to more or less match the carbons.
One other thing, I shot a 600.6 grain arrow through the chronograph, and it averaged 175fps. I'm pretty happy with that number.
I cannot imagine how many hours you must have spend figuring all of that out, not to mention the level of detail you put into your video- hats off to you. Looking forward to your video of the first kill!
Any who, very nice work, enjoy showing it off and every second you get to shoot it!! Keep up the great videos as well!
