Rough Sawn Lumber

Postby norriscathy » Sun Dec 30, 2012 4:02 pm

Is it really necessary for all lumber to be planed? Except for those pieces you are ultimately going to finish; it would seem that you would get more lumber for the dollar by using everything rough sawn. I've read many posts about roughing up white oak before you glue it, why not just buy it already rough? What am I missing here?

Besides not having that "finished" appearance, my experience with rough sawn lumber is that is has ripples, saw marks, that do not offer a smooth glue-up surface. Doublers, strengthening members, are typically laminated at the frame joints. It seems that this requires respectable flat-ness of the mating surface.

Try getting a nice painted finish on it! Impossible.

Just picked some white oak 4/4 rough sawn this am for battens. In this form, besides everything mentioned above , the boards need straightened on the table saw, and are very rough. If it can give you splinters by carrying it around, probably too rough to use. :shock:

I agree splinters alone would make it questionable. I have been a woodworker for many years and even though I have the tools to deal with rough wood its typically not worth the hassle or cost savings unless your dealing with a large volume.
