I'm new to this but have tried it and it worked for me.. I would wait for others to chime in...
Twist limb: take a small cotton towel, soak in water, squeeze the towel, with the towel still damp (saturated with water), throw in the microwave for about 2-3 min on high. THen take ot out of the microwave and wrap it around your twisted limb (do it with glove so you do not get burn by the steam and hot towel) for about 5-7 minutes. After the wait, physically twist the limb in the opposite direction, careful not to over do it. Once you are happy with the results and the bow is somewhat cool, string it up and position the string to pull the limb to the center (if need me), hang it on a peg and leave it overnight. Pull string back and lower back to the bow several times and see if it is corrected. I was told to do this by a respected archer at my range, I was hesitate at first but eventually tried it and it worked for me... 1950's Bear Grizzly
