Question about deepening nock to correct twist
« on: October 15, 2018, 07:11:15 pm »
Not 100% sure about wich side of the nock i should make deeper so thought i should ask before i try it. In my head its the left side (weak side) on the 1st picture, right? Tried removing wood from the strong side but to no avail, and dont want to lose any more weight. http://imgur.com/gallery/gjVAXmd
Heating and bending is not really a good option either, would screw up the horn tips and lose the shape of the recurve.

As you can see the string lays on the edge, i can shoot it without losing the string it just looks like shit. String tracks dead center in the handle. It had this twist from the beginning, but couldnt figure out how to bend in the recurve in the caul and correct the prop twist in one go. Guess i would have to make a caul that is leaning slightly to the ooposite side?

I have heat treated most of my static recurves to tweak one or more of the tips a little to get the string to lay perfectly in the groove. You do your bending down from the nock just a little and aim your heat gun toward the handle to heat only the area away from the nock.

I tweaked this hickory static overlays and all.



I heat the area just below the nock, put the nock and a little more of the limb in a padded vise and give the handle a quick twist. I let everything cool then string the bow and see if I made enough change. I don't keep the pressure on until the limb cools, one quick adjustment then out of the vise to cool. I may adjust a couple of times to get it right.
