The last takedown longbow I made I tillered even to shoot 3 under. It tunes for 3 under at a nock of 9/16" perfectly. Here is the strange thing. It will not tune for split finger. No matter what nock height I use, 1/4" to 5/8", it clangs and bangs and say no split finger. Has anyone else run into this when you tiller for 3 under?
