So I have a question about reversing limb twist on a Bear Kodiak Magnum. Someone gave me this bow. It has 1953 as a printed date on it. I am not sure of when it was made. That aside, I have researched on this site how to reverse the limb twist but all I can find it that someone twisted it back. I am not having luck doing that. ):
Is there a process that will not compremise the limb?
For reference it has a serial of 96L5992 is AMO 52" @ 48#. It has green glass ofver the limbs.
Thanks!

In most cases it really is just as simple as twisting it back. It's just that some are more stubborn than others.
Start by stringing the bow and lay it on a table or flat surface. Gradually twist the limb in the opposite direction, and keep working at it. Leave it strung up and repeat the process from time to time. Eventually, most twists will work out that way.
Remember that it probably took a long time to put the twist in it (usually be the old "step through" method of stringing) It might take some time to work it back out.
Sometimes it takes more than that though, and there are various methods to work it out, including heat. But that can be dangerous if too much heat is introduced. It could result in the glue failing and the entire limb delaminating. Extreme caution is advised!
Most of the time simple is better, and working the twist out by hand is the prefered method. Although it may take some time and effort, is much safer for the limb.

Martin, There was an article in TA about that. He used hot tap water, twisted it back past a bit, then ran cold water on it to set. I bought an old Pearson for $5 cause the string wouldn't stay on it. Didn't know about the water method then. Put in a padded vice & used a heat gun on it. got it kind of warm to the touch, twisted it slightly past straight, clamped it & let it sit over night. That was almost 3 yrs. ago & my nephew still shoots it. No twist at all.

Joe and Butch,
Thanks! I have put it on a Air Hockey table with a 20# weight holding the handle flat to the table. It is braced. I slid some rubber under the limb end to lift it from the table top. In this position the string is centered. I am going out to a meeting. I should be back in four hours. I'll check it when I get back.
The guy said this was his dad's bow and was sitting in the basement for 20 years. So yeah, it took a long time to get in this condition. (:
Again, thanks!
