Here is my history of tillering.
1st bow: I floor tillered too much. The guy showing me the ropes doesn't like tiller stick, or tiller tree, he likes to do thing by sight, so a tiller he thought was fine, I thought would be a hinge. So I fixed it later.
2nd bow: I floor tillered this one pretty good. Could barely get the string on to brace to 1". Kept the limbs evenly bending the whole time. Got to the point of 55lbs@24", and did something stupid and tried to reverse bend to get out string follow and it exploded.
3rd bow: Great floor tiller, great bend, got to target wieght, but wanted to take out a dog leg and heated too much, bent too much side to side movement mid limb and got too thin on one side. Shot fine for 100 shots and broke right where i heated.
4th bow:Not bad, not finished yet, floor tillered to where I could barely put a string on. Put away to work on this summer.
5th bow: IPE/Boo. Everything is going great. Too good, want to keep it up. But have that leary feeling things could go bad at a moments notice. Only working on 1/2 hour a night. Have her to 2" brace, and pulling 12". Limbs are almost evenly bending with 10" of stiff limbs from the tips. Moving only 1" at a time.
