I have two cedar boards rough cut 1 by 8. Thinking of making a child size rocking chair, they are flat sawn any advice on grain direction for legs and rockers.

Cedar is a noxious wood to work and easily banged up. Another choice of wood would be easier on the lungs and could withstand the abuse a child can throw at furniture.

Regardless of wood choice, I would think the legs would be stronger if the grain direction ran perpendicular to the rockers, that is, end grain at the top and bottom of the legs. Other than that, I am not sure orientation makes much difference.

Sawing the rockers would be the easiest approach, but a glue lamination would be stronger. Sawing the legs limits the number of fibers in the rockers that run uninterrupted from one end to the other of the rockers. The fibers of all the slats making up the glue lamination would remain intact.

Of course one of the problems with glue lamination is that after the polyvinyl acetate (PVA) wood glue has cured and the rockers removed from the cauls, some spring back is likely to occur since PVA glue has a bit of elasticity. I have heard but not tried resorcinol-formaldehyde glue, also known as Resorcinol glue, reduces spring back since it dries harder than PVA but Resorcinol glue requires well-fitting glue surfaces. Resorcinol glue is a two-part resin glue.

Have your say...
