About 10 years ago there was a guy with a promo dvd, selling plans for a router jig, that would rough out pre tillered bows, from dimensional lumber like oak, ash and hickory. He would string and shoot them supposedly straight off the jig(he might have exercised them first on a tiller tree), no adjustments needed after the router.
His bows looked pretty well tillered, low set too. I quizzed him about a few potential issues, and said on a forum that I didn't know if it was the right system for me, because it would take all the skill out of the process.The phrase "its a bit like using dynamite for fishing" was used by me. It wasn't meant as a criticism of his idea, more about whether it suited my personal bowmaking philosophy. Unfortunately he took offense and I haven't heard or seen any more about it since. Quite a shame because I think he was onto something interesting. Even if it might not deliver perfect results every time, it would at the very least serve as a useful method for roughing out a floor tillered bow ready for further tweaking.
