A tip wedge is thicker at the nock and gets thinner towards the riser--4,6,8" long
you could make your wedge stick out (longer than the stack) and let it bump up against a nail to keep it from squirting out

5" radius and under don't need a wedge-- a 2" radius will make it static

You  can see all the limb is working--18-1/2" working limb

Anything I post on here is open for discussion...  Do some of you have thoughts on floppy and vertically unstable limbs and shootability??

  Do any of you experienced bowyers have any opinion on floppy, vertically unstable limbs???  I am repeating the question because you all may have been busy with Christmas stuff...

Absolutely...There are a lot of bows on the market being built that are borderline what i consider "vertically unstable"  Grabbing the string in one hand and the riser in the other you can easily move the string up and down moving both limbs. Another test is standing the bow on the lower limb tip vertically and push the top limb tip down with your hand. It easily wiggles both limbs causing limb bulge....

With all this said, vertically unstable bows can still be very high in performance, but squirrely too....They are very sensitive to finger placement and release consistency. Take this unstable bow, and bring it to full draw... then rock your finger pressure high and low a bit.... You will notice more a lot more movement in the limbs with a vertically unstable bow.

next thing to ask is .... What determines a limb design that is vertically unstable vs a rock solid one?  That answer is very long, and many options and opinions, but it starts with geometry......  Was that helpful?

  Yes...  That was great...  Yeah, I think some bowyers sacrifice shootability for performance or what's trending...  You can have both if you put in a little effort...

Thank you Arlo
