Title: limb straightening question
Post by: Shaun on December 17, 2008, 07:33:00 PM
I recently got a 72 Super K with the bottom limb tip out of line to the riser side about 1/2 inch. Hot water bath tub tap method and hand pressure moves it back in line and it stays when cooled but it creeps back to the bent position after it is strung and shot for a while.

Should I apply more heat with a paint stripper gun and clamp it passed straight? Clamp it in a form bent a little passed straight and run it through the curing cycle in the bow oven?

Any other suggested methods?

Shaun, I believe you'll get a more permanent fix if you'll string the bow and spend several minutes per session, several sessions over a period of a week or ten days of counter-twisting the limb as far as you can without throwing the string. I would also leave the bow strung until the correction seems permanent. Although this takes more time than using warm water, I've found the "fix" to be more permanent. Good luck-it'll straighten out.             Grant

GY is correct.I do not ever use any heat what so ever.The bow was laminated at 120 degrees if you excede that temp with 140-160 degree bath tub water well you can see where this one's headed.You may cause more problemo's then you have now and no heat guns for sure.They are real bad news around laminated bows.The lower limb is most likely twisted from step thru stringing methiod.As Grant said work it cold while strung with out throughing the string off the limb(twisting to far)and just keep at it and it will start to work itself out.Shooting and twisting is the best formula.I don't want to sound like some know-it-all but I have straightend several hunderd plus bows with no heat.keep us posted bowdoc

I twisted the tip on a Jack Howard Gamemaster Jet a few years back.  I asked Jack what to do and he told be to put it in a hard case unstrung and leave it in a hot dry place for about a week.  I left it in the back seat of my car with the windows up.  When I took it out the tip had returned to the proper position and I have not had a problem with it since.  The importance of putting it in a case is to insure that it is not resting on the tip that could put pressure on it.

Another suggestion is a propane torch and a stilson wrence.
