flipped tips on a glass bow?

[fujimo]

from a performance perspective( speed vs stability) how viable is a straight glass bow with flipped tips, like so many of the beautiful osage bows that i see.
is this just a method to add zip to a straight stave, and to allow for a shorter bow (string angle)?
how does this design in glass compare to a glass RD bow.
i am sure it has been done a-plenty, i just havent seen any, and i really would like to see some pics, and hear some thoughts.
wayne
would one still reflex the bow some,or not? and then "flip the tips"

Check out my website and look at the Talons. It works great
God bless you all, Steve

any other ideas out there

Can't speak for glass bows, but flipped tips seems to benefit longer limbed bows that have short handles/risers such as all wood/selbows. I think the flipped tips, by stiffening the outer limbs, benefits any bow that has shorter risers. Long limbs are just that, long. Flipping of stiffening the tips is just one method to help reduce limb vibrations and reduce some hand shock.

So I would have to say that stability is the greatest benefit......Art

I'm kind of new to bow making, what are flipped tips?

[Art B]

That's where the outer portion of the limbs are reflexed vs recurved....Art

Basically you are stiffening the tips with the reflex and shortening the working limb. this not only helps with string angle, but it also stores energy in a shorter section of the limb... that's where the "Zip" comes from. the same theory applies with a working recurve vs a static tip.

what you are getting is a static tip long bow by adding a tip wedge and reflexing it.... on a wood stave you flip the tip.... on a glass bow you are adding reflex to the shape of your form.

This is a 54" long bow drawn to 30"..... see how much of the limb is bending here?

Wayne,
Have a look at the old 1950 ish Bear Static recurves no reason why that cannot be done today, if you can't find a picture let me know and I will post one for you to look at.
I build a BBO Tri-Lam to sort of copy the shape, it shoots like a house on fire.
How's the fishin'

fishin is about to start in the next month , i would love to see some pics, and of the BBO trilam too.
whats the best way to send you a surprise?? bus i geuss!!

[fujimo]

thanks for the responses guys.
so is there an advantage of doing this on a glass longbow.
i really prefer longbows- and if it will give a bit more zip with added stability- thats a good thing!! right??
what would be the negatives of doing this,
and how does this design compare to a RD longbow?

[Bert Frelink]

Wayne,
I feel that there is so little difference that it 's not enough to even worry about, more zip and added stability is ALWAYS a good thing, but.............there is a point of no return.
Negatives,= less zip and less stability???/
Compared to a R&D, MHOP, no difference!

Wayne,
Here is a picture of a bow that was build just about 59 years ago, ask me if it was speedy or stable enough to do what it was designed for?
 
Take care.
Bert.  

[fujimo]

look at the strung profile of that bow, they sure do look cool!!
i think i will build one!

[Swissbow]

How about something like this ? Ronny, a friend of mine just recently built it...

[fujimo]

nice set up swiss.
any unstrung and full draw pics of it.

[Swissbow]

Hi Fujimo, here she's at full draw...

 

I don't have an unstrung picture, but I'll ask Ronny. Until then I can show you the drawing of the profile of the bow.

I seriously hate to bust you guys bubbles but those bows are called recurves. They are no longer longbows when we do that.

God Bless you all, Steve

Mine isn't a recurve.   :p    :p    :p
