Heavy weight bows

[bownarra]

I've just sawn up some labernum logs that were in my stash and got some sweet straight grained lams. I don't have any plum but labernum is also highly elastic......
I might have a crack at make this - just for giggles.

[Marc St Louis]

The reason I would have used Plum, or Osage, instead of Yew is because of the density of the wood.  Top grade Yew would work well but it would have to be high density wood and I don't have any that is suitable.  A bow made from lower density wood would have to be made physically bigger in size

This style of recurve would be my choice for such a bow



I may think about making such a bow when I have nothing better to do

[Badger]

  A bow of that style even approaching 100# would be a sight to behold. If you ever get the urge to build something in the 100# range or even slightly less I am sure Joseph the hungarian flight shooter would love to shoot it.

[PatM]

I would just make it  a self reflexed static, no deflex or splice.

For regular flight or broadhead?  Is 100# his limit?

In some ways Pat a straight handle recurve would be harder to make.  First of all the bow would have to be made longer and second it would be harder to brace especially if it had a fair bit of relfex. 

A tough build anyway you look at it

[PatM]

The length would depend on the size and angle of the recurves.  I don't think it would  have to be longer than 64-65 inches if the width was right and the statics about four inches long.
 I would smoothly crown by sanding ridges down and sinew back unless an unusually smooth back was available. Even natural ripples and waves on a clean back would be risky.
 Not too many woods actually grow that way.

[Marc St Louis]

I wouldn't make a 65" recurve for a 30" draw unless it was sinew backed and I wouldn't make a sinew backed bow for someone unless they specifically asked for it.  Too much maintenance with sinew for most people

  Mark, I think a bow like that would perform equally as well for broadhead or flight.

I think the major problem would be the string.  Such a bow would have extremely high string tension and the need for a natural string in Primitive Flight would make it next to impossible to keep a string together

[BowEd]

What a bow!!!Just my observation here are there any flight bow shooters that use an Egyption style design bow?Angular so to speak.

Would it have a higher tension than a 180lb longbow?

  Beadman, I have played with the angular bows quite a bit from all wood designs. I have a huge problem making weight with them and when I do make weight I have a problem with stability at brace, for some reason they really want to twist. Bows like Mark's in the above picture tend to be about the fastest from what I have tested but even at that the differences in well made wood bows is not huge. The amount of reflex seems to be the biggest single factor as long as mass is kept under control.

A 60# recurve like the one above has higher string tension than a 100# longbow

 Have you heard any word on how Joe Gibbs is making out with that 156 pound(I think) composite Adam sent him?

 Jaap Koppedrayer had an Assyrian type bow at the  salt flats a few years ago.

 It seems that the best design for flight is still the reflex/recurved bow. Even if deflex strains the wood less a reflex still seems to hold the edge in the best shots a bow has in it
