what causes string follow....

billmac:
besides the wood being too moist?  (do I mean set?  are the terms interchangeable?)

Thanks

Hillbilly:
Some of the other things that can cause it: uneven tiller, bow too narrow/short for weight, pulling the bow past its intended weight while tillering, pulling the bow too far during tillering with uneven tiller, and mainly,the laws of physics (wood will naturally take some set, if you start with a straight stave, you're going to end up with some follow unless you reflex it to compensate.) Don't worry too much about it unless it's excessive, some follow is normal and doesn't hurt a thing. Notice in the TBB that Baker describes bows with 1 1/2" of string follow as well-designed and efficient. If you get several inches of follow, it will hurt performance a good bit, but doesn't mean that the bow isn't a shooter. I believe Rod Parsons used to win a bunch of matches or tournaments in England with a bow with about 3" of string follow. Most of the bows you see on here that have the tips even with or ahead of the handle were forced into reflex before tillering. This can increase arrow speed, but can also make the bow less stable and make it a bitch to tiller if it has a bunch of reflex.

Hillbilly:
PS-we often use the terms "set" and "string follow" interchangeably, but technically, they are a bit different. Set is the amount of difference between the stave before and after tillering. A bow that started with 6" of reflex and ended up with 3" of reflex has taken 3" of set. String follow is usually a result of set, defined as the distance that the tips of the finished bow lie behind the handle. A bow that started with 2" of reflex and wound up with the tips an inch behind the handle has taken 3" of set, but only has an inch of string follow  :)

Well said, Steve.   Pat

Steve, I didn't know that distinction between the two...thanks! Now would the term "deflex" apply to a predetermined design intention of deflexing the limbs to be followed by recurved tips? I had always thought of "deflex" in the same light as "set" and "string-follow".
