View Full Version : Keel timber: laminate? change wood?

12-09-2005, 01:30 PM
The plans for "Maid of Endor" call for a white oak 4 x 6 for the keel. No local suppliers hold out any hope of getting that here. They can, however, get me lots of Doug fir in the right dimensions.

Advice? Am I better to laminate the keel from two oak 2 x 6s, or use a single fir 4 x 6? If I use fir, do I need to increase the size to achieve the same strength?

Larry Pardey has used laminated timbers on both of his boats.

If you can get a nice high ring-count old growth D. Fir, use it. If you can't, I'd laminate 3 horizontally stacked D. fir planks.

mmd -- would you use that fir (either solid or laminated) at the same scantlings as the plans call for in oak?

Maybe add an extra bit of moulding to compensate for the lower tensile strength and higher elasticity of DF. Say, make the keel 4" x 7".
