I imported two rough quarter sawn spruce planks (8" x 3"x 12 feet from memory) from Canada years ago by ship and had it milled and finished to size by a local cabinet maker to get all the pieces I needed. There was some wastage due to the cutting process and rejection due knots/ flitches/ ring count etc but it worked out a lot cheaper and I have been slowly selling off good left over bits over here in Australia to further defray costs.
Now I find native to Australia another conifer called Hoop Pine which also does the job albeit it a little heavier and it is laminated to make select grade ply.....cheaper again. This wood was also used in certain aircraft built over here during WW2 and there are aviation specifications still available for it.

My grey mater has firmed up a bit lately but I recalled seeing the instructions somewhere of laminating material together to get the required size of material. I found it in a 1981 Wick's catalog. WIck's was probably the main supplier of material and I'm hoping the Brit's will accept the fact that laminating was an accepted procedure and probably hundreds of KR's have flown using that method.
