In Response To: Strip: Internal strongback (Craig)

Hi,
I am also a newbie. I am also about to start a project on a pair of Great Auks (check out my question posted regarding length of strips to go the whole length). I don't trust that an ordinary 2X4 will remain straight. So I am building up a strongback out of a material called variously: partical board, flakeboard, or fiberboard. Imagine taking coarse-grained sawdust and glue and compressing the hell out of it. It is often used as underlayment for floors. It's also extremely dense and impossible to warp, tends to be stiffer than ply. Do not confuse it with what I call beaver board, which is made up of compressed chunks of wood and glue.
The stuff I'm using is 3/4 inch thick.
Good luck,
Bill
