Title: Tiller

Do recurves affect the tiller of a limb. If we have a pyramid limb with even thickness that has perfect arc of a circle tiller and recurve the tips will the limb still have perfect arc of a circle tiller?

Interesting question as always Don. Do you mean a working recurve (I think of this as flipped tips that work a little) or highly reflexed limbs (as in a R/D design)?

Either actually. It's a hypothetical question. I'm think along the lines of the recurve maybe torquing the rest of the limb as it "unwinds". Maybe that torque, if it even exists, will cause the outer limb to bend a little more.

Other than adding a bit more stress it shouldn't change the tiller.

   I have recurved quite a few bows after the fact. besides dropping the weight I don't remember any major tiller changes.

Thanks just a curiosity thing.

What Steve said... I usually tiller a bow to first brace leaving the tips stiff and then put my recurves in. Don’t really see a difference in the tiller after that...
