Just how much set does it have? If I had been making bows for six years and decided to fool around with a deflexed bow from Year 2, Project #8, that might be a plan, but not the first one.
Actually, I just did the former over the holiday with a hickory number made in 2003. 66" long, out of the sling it had 3/4" set, 65#/28". Over a few months it went to 2" set and dropped to 61#. unheattreated hickory in the late summer. Last Dec., I dry temperred the belly on the outer 2/3 of the limbs. leaving a little of that cenral deflex for a bit of an r/d feel, and gave the tips a little extra bend. Also thinned the tips a bit. In my seond year of bowyering, I had graduated below beg toe tips but they were still a little ungainly compared to more recent projects. This put the tips out 2" past the handle. With excersize it settled in with the tips 1/2" out reflexed beyond the handle, and sent up to 68#. Time will tell how it holds up. I didn't mean to work in on your thread so much, but since it was so relevant, I thought you might like to hear about it.
