Listees: I think you can use Doug-Fir but it really should be 1/4 sawn ---Logs are cut such that sawing of the logs into boards is done in such a way that the direction of cut is 90 degrees to the grain of the wood---- This reducethe dendency to warp twist & deform, also the planks used should be absolutely free of knots, pitch pockets and all other defects. Spruce has gon thru the roof because good old growth timber is hard to find and then the 1/4 sawn requirement creates a lot of waste. What ever you do you should use material that matches the shear and bend stress of spruce as well as moisture content. The Desity may be higher so craft weight will go up. I think it can be done. but care should be taken.
