Recurve out of alignment. Is this limb twist?
« on: April 26, 2025, 01:02:38 pm »
So, whilst shooting this thing in and doing the final sanding and such, I noticed that one of my tips is a little out of alignment.  It isn't a big problem for shooting--the string is almost perfectly aligned with my shooting side of the handle, which I like--but if it's limb twist, I'm afraid shooting it will make it worse, and I'm also a little worried that the string will miss the bow and unstring itself when I shoot.  I'm no physicist, but I can't imagine that would be good.

What do you think?  Do I need to do anything about this, and if so, what?

See how that lower limb kinks off to the right?

It doesn't seem as visible when the bow is unstrung, if that matters.

Check the limb thickness from side to side out near the tip. Uneven thickness will show itself under tension without showing in the relaxed, unbraced state. If that is the case it should be correctable by evening out the thickness from side to side.
 It's a good idea not to add skins until you have put 100 arrows through the bow so any maladies show themselves. If heat or steam is necessary to make the corrections that can cause damage to the skins.

I agree with Pat in that it looks like it may be limb thickness from side to side on the width of the bow. But I guess it doesn't really matter that the skin is on there tho because you would have had sinew on there anyway and steam would destroy your sinew the same as it would the skin. Meaning you would have to reapply sinew and it would change your tiller all up again. I would say make sure the bow isn't twisting so much that it is putting the side of the bow towards the back. That would put tension on wood that has no sinew and cause it to explode haha. If it is then remove wood from the side the bow is twisting towards. But if it doesn't bother you asthetically and it isn't twisting to an extreme amount then I would suggest to leave it cuz removing wood would mean lowering draw weight and I I think you said on your last post that you were already disappointed with the draw weight.

Yeah, Pat, I know, I'm kicking myself for adding the skins before I shot it in.  Dumb.  Won't make that mistake again.

Pierce, you might be right.  Maybe the skin doesn't matter for this issue.  I still wish I had waited, because I took away the option of adding another layer of sinew to up the draw weight a bit.  Oh well.

I'll check the limb thickness.  It doesn't seem to be affecting the limb as a whole, just the tip, so if I have a thickness inequity, it's probably just on the tip.  Stand by--I'll let you know.
