Title: Does bamboo backing help keep the limbs straight?
Post by: Zradix on October 29, 2013, 04:32:00 PM
Hey Gang,

Thinking of making another backed osage r/d bow.

Last one was a BBO.
Boo splintered even though I didn't scrape the rind off...just lightly sanded.
So it has me a little apprehensive to use it again.

Been thinking of using a hickory backing this time.

Just got to wondering though, if boo might be a big help in keeping the limbs from twisting/curving do to its linear nature.

You think it makes a bit of difference when compared to hickory in that aspect?

Thanks    :thumbsup:

stright grained wood and bamboo has fairly low torsional strength. That was sometimes they use bias ply glass in bows. Most carbon is bias to add torsional stiffness.
