There is several different philosophies on how to go about staightening a limb. Some swear by using hot water, and some use a hair dryer or a heat gun. Then there are some that say you souldn't heat the limb at all. it IMO it all depends on how the limbs were made and the materials used. What i do to really get a good idea on how far its twisted is use an 18" tiller stick. its just a piece of lumber that is shaped to fit in the hand grip on one end, and a string notch in the other. just use a small rounf file to make that. once you insert the stick you can look at it closely while applying some twisting presure on the llimb with your hand. That will give you the right direction and amount you need to go..... The last one i straightened took two sessions but it finally stabilized after adjusting the string notches in the tip slightly. i had another one so bad, i took the string oof and put it in my bow press first. just something to hold it while i worked on it...a vise with a towl protection would work too. or a clamp on a work bench or table. after getting the bow clamped down, i took a 10" cresent wrench and hung in on the limb tip.....just the weight of the wrench will twist it some. the one i had needed more weight, so i hung fishing weights on the end of the wrench untill it twisted it about a half inch past where it needed to be. then i took a hair dryer and slowly warmed up the limb. NOT just the tip, but the whole uper portion. after it was all uniformly warm to the touch. i just left it over night to cool and take a set. It worked excellent! And it stayed put too......Hope that helps.....that was my winner....Kirk
