Well then it can't be optimum. ;)

   Well, I said it can't be done with wood. It actually can if you are willing to make the limb wide enough. Like maybe 4". I might try it with some 1/4 sawn white oak and an osage board. I did an osage self bow similar a couple years ago but with less working limb. I went about 2 1/2" wide. I had exceptional performance to start but it rapidly broke down.

So basically a Turkish bow....

  Pretty much but you can't do it with wood.

I think, when I start tillering this back, I am going to get the tips to start bending first, then try anf move the tiller to the inner limbs. That way the inner limbs release their energy first, and the tips act like the flick of the wrist as a ball is pitched.

  This seems like a tricky proposition. Which part will bend in order to achieve brace?

Im thinking  with the fades being deflexed only the outter third will need to bend.

Without adjusting tiller I braced the bow. String tension is completely through the roof. I am moving, my scale and tree is packed away. This weekend I am going to a shoot in Missouri so I can give numbers there.

I just unbraced it and the tips are perfecly even with the back of the bow. I think everything I did was worth it.I have a set of arrows there waiting on me made by warpath for this bow too so, this will be fun :)

I did however get to take the bow to about 24 inches of draw and fire an arrow. This arrow was completely fine, and had been fired from this bow plently. I just shot the ground from my porch. It hit the ground with such force it split itself open along the grain line in 3 pieces. This bow is powerful.

Very.

The tips when blaced, protrude higher than the belly of the bow( the string rest on the recurves with file grooves cut in ). I beliece I will be trying to make a string that splits open allowing the string to sit on the nock, split across the limb, half the sting on the right, half on the left, and join together at a sort of bridge/brush nock further towards the outter third of tje limb than at the start of the recurve.

This in my mind will allow the bow to increase in length as the string is drawn, and allow the recurves to really work and " flip the wrist " as the string slams home on the last part of the release.

Got a skull out of the dirt with your name on it and it looks pretty good...except for the bullet hole in the forehead.

Thanks buddy, I think this bow is turning out fine.

Id really like to meet you and have you give me that skull in person.

   ??? Sailors... ::) >:D. I'm glad you got some improvement out of your effort.  I was wondering if you had looked into Wichita for employment.  My cousin worked at Boeing for a couple years and said it was good place to work.  The only reason he didn't stay is because of the long commute and he didn't want to move.  Josh

reminds me a bit of this 200+fps at 10gpp glass bow's shape



  I am convinced this is the optimum design, maybe 30% less bending limb.

Does anyone know the length/width of this bow?

Sleek - I bet that piece of osage doesn't know what's hit it.....!!!! Get your self a piece of maple some horn and some sinew. Wood has it's limits you need more elastic material!

It might be doable with bamboo, at least up to 50# or something -

fibergrass :D

Sorry, not sure if it's a "commercial link", remove it if it is and I'll stop posting such links

Also... the "strung length" of that glass bow is 45", with a 30" max draw, and bow mass 250 grams. It looks a bit longer than 45"...
