I have another piece of oak that i ripped off of the first one, the grain runs slightly diagonal from the corner to about half way on the opposite side(when looking at the end cut) without the "flames". the side grain on both sides are parallel with very little, if any, run out...is that a better choice, or forego this board altogether?

Either of those pieces might work out if you add a 1/8Ē quarter sawn hickory or maple backing. Not sure if thatís the route you want to go, but it should make a decent bow as long as your backing is good. I would also recommend adding a power lam under the backing to help keep the handle from popping off

Hope this helps,
Taylor.

I am going to offer a couple of suggestions, you do have to back your board, your handle transition to the limbs is much too abrupt, it WILL pop off.

As for the handle I have found if you put down a couple of 1/8" lams between your handle piece and the limbs and make your fades about 2 1/2" long your handle will stay on.

Like this, I have posted this many times before.

not sure what you are saying as you can tell little about the grain from the end cut. some use the term grain and rings lines interchangeably but they are not the same thing and makes these discussions confusing. you can tell something about the grain from some views of the ring lines, but not everything

a pic would help

Eric, assuming the laminations are of similar hardness/stiffness wood as the handle wood, what do you feel they are doing for you in that assembly? Unless the glue is less stiff than the wood there should be no difference between a solid handle piece and the laminated one from what I can see. The more gradual fades will make a major difference to how well the stresses are transferred into the handle and if it stays on or not.

I believe the multiple thin lams create greater strength in the glue lines also, further preventing the handle from popping off.  Thatís all I can think of.  I wouldnít ever try to make a unbacked board bow if the lines on all the sides didnít run the length of the bow.  Those boards are destined for unbacked failure.

Look at the edge grain. Look for straight or nearly straight. A couple of run outs per limb are ok.

It appears the lams can bend a little, separate of the main handle piece, all I know for sure is they work to keep a handle on. I never analyze bow making into the small individual parts, if it works it works, if it doesn't it doesn't.

Interesting. If the lams move separate from the main handle then that is due to the glue being weaker or less rigid than the wood or the lams are weaker/less rigid wood than the main handle. I like the laminations because they offer the chance to use different woods and increase the eye appeal with some colour and contrast.
