An experimental warbow

Mark, just for the heck of it I figured out what I would shoot for on mass for that bow, with a 12" semi stiff center I allowed for a 6" center stiff. For a self bow it would be about 34 oz, for a backed bow I take off about 10%Which would put it close to 31 and then if you are making it for flight I would try and get it down to about 28oz or 29 oz. Do you know what the stave weighs now untillered? Steve

Justin Snyder:
Mark, Steve and Rich, thanks for posting this.  It is exciting for me to watch someone build a bow, but for you guys to post your thought process as you go through it is immensely profitable to the rest of us.  I wish I could understand the thought process a little better in the design and building for better performance. I understand Steve's mass formula, but it is such a small portion of the process.  Thanks again, Justin

Richard,
I'd be interested to see some pics of your RD longbows.
Steve,
Right at the moment the bow is at between 29.5 and 30 ounces. I'm guessing some will come off that in tillering but not too much, but there again it may be underweight! The bow is somewhat overlong but will be safer in use for it. I hope the weather is good enough tomorrow to get outside and do some more work on it.
Justin,
I love the making of bows and the shooting of them, but one of the best things is that you can think them through during any work day. It is interesting to see if the thought process actually works out in practice, and of course mistakes are good learning chances, even if they do get a bit boring at times! I have spent quite a time thinking strange thoughts, putting a lot of hours in and made some lovely broken bows  ;D So far these have all been experimental ones I have made for me, which seems a little unfair.
This bow should be failry safe, it will just be interesting to see how light I can get the tips with the etra bit of semi-recuve reflex at the ends.
Mark

Badger:
It is kind of facinating trying to figure out what makes these things tick. A year ago I built an osage elb about 140#, didnt take any set to speak of but had lousy early draw weight. Since that time I have built many others whith much lower draw weight but having much higher tension at brace. I am convinced that the key to good performance with these bows is to not overstrain them durring tillering, wether or not it manifests itself in string follow is irrelevant compared to the brace tension we maintain.

Wow, that's so simple but totally true.  This is interesting guys.
