can cherry be used?

<< < (2/2)

davidjw:
Definitely get Adam's book somehow, every now and again they pop up used on popular auction and book retailer sites.  But as a short answer to you questions;  Cherry can be used for the core as long as the grain is good and there are no knots.  But not for bows over 50lbs, if I remember correctly.  A SG of .65 or higher would be required for that.  You will hopefully get the horn on before you sinew, and only do any tillering after the bow is finished and seasoned, it's all precise measuring up until that point.

I would be inclined to think that this is not entirely correct.  If the wood has interlocking grain, such as Elm, then a lower SG would probably work quite well for heavy bows.  Unfortunately Cherry does not have interlocking grain

davidjw:
Yes indeed you are probably correct, good point.  However, woods with interlocking grain are often avoided do to the difficulty in grooving.

davidjw:
On second though, would interlocking grain allow for more shear stress, and that is why a lower sg wood might work?  I am probably missing something, but at a glance SG seems to correlate more closely to shear strength then grain type.
