I don't think I would bother trying to laminate two boards like that. I've scarfed a lot of short pieces together to make a frame, and it was a real time drain. Its definitely worth the cost of buying proper lumber up front if possible. Unless you already have a large quantity of adhesive, that alone may be more expensive than purchasing new lumber.

Otherwise, as long as an appropriate adhesive is used (along with appropriate clamping technique for said adhesive) it should work just fine.

: I'll have lots of questions, but the immediate one is about wood for
: stringers. I have some red cedar clap boards left over from the house.
: They're wedge shaped in cross section, but if I stack 2 they make a piece
: 3/4" x 5.5". Would laminating them effect the way they bend, and
: would it be worth the trouble? Thanks!
