Static tip vs. non static tip recurves

[Kopper1013]

Hey fellas think about building a recurve next and was wondering what your thoughts where on static tips vs. non static tips?

Is there a significant performance difference?

I don't believe my Black Widow PSF is a static tip recurve and it performs extremely well. I guess I'm curious why some of you like the static tips?

positives vs. negatives?

Can they be build in one piece bows with tip wedges or just three piece bows?

Thanks your input and thoughts

check out mark daniels posts- built some really cool 3 piece statics- he should be able to give you some real values!!

and young Ben builds the meanest all wood recurves/ hybrid, mail him for some real insight!

Bowyers bible 2 talks about it making the bow faster.                     My static tips have to much angle so I took some out.                 I want my string to lift off the bridge and be hindging on the nocks at 18/20" of draw.                                                               They need to be light weight to work well

I now use a stack of .350 on top of my fiberglass stack 7 1/2" long static.
 

The belly side at the bridge is 1/2" wide and 3/16 wide at the nock
The back side at the bridge is about 1/4" and 1/8" at the nocks  (static tips are triangular in shape)

Very cool mark thanks for sharing, looks very challenging to build one "right"

YES

Can tip wedges be added to help act more like a static tip then not?

[bornofmud]

Yes, tip wedges can always be added to stiffen the tips.  The advantages are that if done correct, you get a small speed boost and more importantly, quietness and smoothness of draw. Recurves can produce extra sound from the string smacking the belly of the limb on release, statics if done correctly eliminate or atleast reduce that problem.  The cons are that they are harder to get right (less wiggle room to get it to bend how you're intending), and are harder to keep stable.  The latter is the bigger issue, the longer the hook, the more mild the angle; the more intense the angle, the shorter the hook is a good rule of thumb. Can still get pretty adventurous with the limb shapes, just have to do everything else really perfect.  Been working on a static design for a little while now, hopefully start to see some decent bows from it soon.

What do you mean by "stable"? I've only built long bows no recurves yet, are recurves harder to build?

[bornofmud]

Yes, or atleast less forgiving of errors.  By stable, I mean the bow's tendency to twist in the limb due to user generated forces (torquing the bow). The more stable the bow, the more forgiving it is of user error, and thus is one of the most important qualities to focus on when thinking of your design.  Speed is great, but speed without stability is pointless.  Luckily, both are possible, just takes some experimenting.  I have yet to make a (imo) satisfactory recurve, but am starting to close in on it, another bow or two and it should be moving how I want it to.  Unfortunately, the project has been on hold as I have a few longbows to make before xmas.

I have worked on my static quite a bit and I have a fast quiet bow.
My full curve was fast and loud but I now have it stopping near cold with very little vibration after the shot.(my opinion)
It a hard choice to Make now that it is much quieter.
