i made 3/8" panels in a hutch, took 5/4 stock resawed it, bookmatched it and glued it up used cauls to keep flat and then sanded down to 3/8" finish thickness. not rouble except for one glue streve spot which i re opened and reglued and it is doing fine been several years now and still lookin good. the panels were around 14" wide and the hutch was 75"tall.oh and the joints were all but joints no biscuts.. just planed to the edges to fit and then glued.
If in Doubt, Build it Stout!
One hand washes the other!
Don't put off today till tomorrow!
