Title: Cypress for center lam in BBI?
Post by: Apex Predator on June 02, 2008, 04:51:00 pm

I'm about to start another tri-lam longbow.  This one will be a Hill style about 66".  I am shooting for 52@27.  This one will have a raw boo back and ipe belly.  I have a piece of cypress that has sentimental value and have already prepped it for the center lam.  It is very light weight!  I would think it is similar to cedar in density.  It has extremely straight grain.  Will this cypress hold up as a center lam?  Thanks.

I'm holding up my glue-up until I hear from you guys!  How critical is the wood in a middle lam?

    I don't see why not. Cypress is really a cedar,and it is lite.

The center lam is in a neutral plain so compression and tension strength wise its not critical but it must be able to take the shear forces at the glue joints. I'm not familiar with cypress as bow wood to make a judgment about it. Pat
