Post another pic with a shorter string (but not braced).

Post by: birdpointlightstring32 on November 20, 2014, 11:29:39 pm: thanks pictures in the work I only pulled stave up to 6 inches placing it on a 4.5 inch brace. Also stave has pith running a channel fully on one limb.

Post by: birdpointlightstring32 on November 21, 2014, 12:47:28 am: I thought about heat treating but I need someone to chime in if heating a cleaned out pith area would harden the edges too much and creating a crack along the sides and corner of pith channel. I think I have all the areas working along the length. Also I had a question in tbb one is says hickory is not sluggish at 9 percent but I also read in volume four that hickory is safe down to 6 percent. What is a safe percent humidity goal with a 47 inch ntn hickory sapling with pith channel drawing goal is 19 to 20 inches and 45 -50 pounds?

Post by: Pappy on November 21, 2014, 05:58:08 am: That is looking pretty good but you really need to shorten the long string,hard to get a good look with it that long, it just needs to be long enough to go from nock to nock . :)

Post by: Lehtis on November 21, 2014, 06:18:58 am: Yes, please, shorten that long string. The bending will change remarkable according to the angle between the string and the limbs. Looong string gives you too much false picture of the bending because of the draw force is pointing to wrong direction. As soos as the tips bend enough to reach few inches brace height, then switch to short string. After that there´s not much to scrape anymore so be careful not to end up to weak bow.

Post by: Springbuck on November 30, 2014, 03:48:21 pm: hickory gets sluggish ABOVE 9%. At 12% it's a DOG. This is helped a lot by heat treating.
