So, you are a first time bow builder or are relatively new to wood bow building...here are a few things to think about before you start!
1) each type of wood has a particular design that works best for it as a self bow.
2) each stave will also have a particular selfbow design that will work best for it.
3) each piece of wood will have a particular selfbow design that will work best for it.
4) each bow builder will have a particular selfbow design that will work best for them.
5) each bow design has a particular length that works best for it.
6)...and each draw length has a bow design that works best for that length.
Any or all of these may have more than one design or style or type but it all should be considered before you make your decision about what you are going to build in the selfbow category.
If you are interested in building a board bow your considerations will be similar but there are also differences. Like with glass lam bows, wood lam bows are engineered before assembly for the optimum end product. Your back, core(s) and belly each has it's own consideration as to the stress properties they each possess for their particular job in the bow.
Backed board bows...
1) what is the best backing material to consider for the particular belly wood, but also the design you intend to use.
2)...or what is the best belly for the backing you have chosen, but also the design you intend to use.
3) what is the best grain configuration for the belly wood used but also the design, draw weight, draw length and use.
4) what is the best grain configuration for the backing you intend to use. If you plan to use bamboo the grain isn't a particular concern.
5)...if you do choose boo for a backing, will your belly wood, design and length support the boo backing.
I have noticed that lots more folks are getting interested in building wood bows; whether they be selfbows, backed wood bows or all wood lam bows. I have also noticed that lots of these folks have already decided what they want to build before acquiring their materials. To me, that is backwards when working with woodbows.
With a glass bow recipe you can decide what you want and then obtain the materials to make that bow. Generally the wood you use will be primarily for cosmetic reasons but also a gluing surface for your construction and many wood species and grain configurations will work.
With wood bow construction I believe you acquire your stave(or board) first and fit the design to the particular piece of wood, species of wood, grain configuration, draw weight, draw length, intended use and any particulars you may have as the shooter.
Just because it is simple doesn't mean it is necessarily easy. Who would have thunk building a simple wood bow could be so complicated. d;^)
A good source if information about these considerations can be found in the TBB series of books. The "Design and Performance" sections of both TBBI and the update in TBBIV will give you lots to consider....and sites like George's and Mickey's, and others will give you proven techniques that have many hours of experimentation, with successes and failures, that will get you closer to your new, self built bow. It is up to you to do your research but all of the info is out there for the taking.
Added to all of this are sites like this one on TradGand, Primitive Archer, Paleoplanet, etc where you can ask questions and get the helpful criticism, suggestions and also see what others have done to get you closer to a successful self built bow. Today, new wood bow builders or wannabes have the best wood bow builders in the world at their fingertips unlike when I and many others got started. Take advantage to these resources and follow a few suggestions from folks that know and you will have a better chance of success. Not all suggestions work for all situations and you may have to do a bit of experimentation yourself and share the results with others. That is what it is all about.
I'm sure I missed a few things so any and all updates and suggestions are welcomed.
