I could use some guidance on picking out 4x6 & 4x8 20' Douglas Fir to be resawn for my Wharram Tanenui build.
It's very beautiful wood. No. 1 & Better, air dried, straight grain. I can pick thru & choose my pieces. I'll need about 12, 4x8x20 or 16, if 4x6x20. Or combination of the two widths.
I saw them a few months ago when looking for a house project. Was amazed at the quality of the beams! Straight, no knots at all, really nice lumber, it looks like cabinet grade wood.
When I get the 4x6/4x8 home I'll resaw them a fat 1/6" over size & let them dry & relax for a few weeks. Then finish them to final dimentions.
Most of the sizes needed are ¾"x2" & 3", 2"x2" and a few pieces for crosbeams 5-½" wide or so.
I know I want grain that runs a long way before crossing 1" out of line.
But how straight is straight enough?
I'm guessing they will be flat sawn mostly. I didn't pay real close attention when was there last.
What are some likely ways they will be sawn & what do I want?
When I resaw them I can cut them to optimize grain direction. But don't know what that is!
If anyone has links or any help, ideally specific directions it would be most helpful and appreciated!
I have been a contractor for many years. It's just laying out & resawing for optimum strength for boat building is new. Not resawing lumber.
