In a continuing effort to promote my fledgling business I have found a tavern willing to help me.

Wow, just noticed the notes at the bottom showed that yesterday, 28 January was the most members on line in one day record.  108 members, and who knows how many guests visited the site.  Pretty active place here.

I think it is a shame you locked out your opinions on plywood Jeff.  I disagree with you on 2 points in particular, and I think they are very valid opinions.

1.  Baltic Birch is not the best plywood for kayaks or any boat.  There are several that are better.  BS 1088 Okoume,  BS 1088 Meranti,  BS 1088 Sapele and AS2272 Hoop Pine are all superior both structurally and in resistance to delamination from moisture.  Whether they are necessary or not is a matter of opinion.  Baltic Birch may be the best bang for your buck, but that is a subjective statement at best.  

2. MDO is no better for kayak frames than other American made Fir plywoods.  The surface is superior to other Fir plywoods, but the interior laminations are no better.  It has the same number of laminations, thus the same thickness of laminations, they are fir and the same glue is used.   It is great for painting, and that is what it was designed for.  Signs are a common use for it, but that does not make it any good for boats or structural items like frames.

I am sorry if this thread offends you Jeff, but there is more to evaluating plywood than your post offers and a lot more to the engineering of plywood than you present.
