My particle board strongback survived one boat intact. When it broke, I spliced it back together with a piece of pine inserted into the hole down the middle and made another (shorter) boat. I've still got it and might be able to get another boat out of it.

: Well, we finshed the first of a pair of strongbacks intended to loft the
: forms of my Razor Billed Awk and my friend's Night Herin. However, what we
: discovered is that Nick didn't mean to "use at least 1/2 in"
: stock of partical board to build the strond back, because when we turned
: it over, the very first time, it broke right in the middle. Ouch! Back to
: the drawing board ...

: The good news is that is wasn't supporting anything and other than about $10
: in partical board the set back has been only in time :^)

: Going to get some ply-wood now ...
