If your osage is from the same tree, or better yet, the same log/stave you shouldn't have to worry about matching them up.
I've made several TDs using just a 4 1/2 " long piece of 1" steel conduit (allow 2 1/4" on each limb for the insert tines) It works fine; not as professional as a 3 piece $40 kit, but it works.
