Keith, David & D Brown....I all want to thank you for your input and advices, but, through all respect to your recommendation, this is not quite what I'm hopping to read neither what I'm asking for advice !...
It's in the "how" more than anything !
D. Brown, to you concern, I thank you again, but bear in mind, I've been doing this for a living over 15yrs, I've got good resources, not to worry ;0) !
But for this concern, lengthwise, it will but but jointed with figer joints, and laminated to position those in a brick layer fashion, therefore length is of no concern.... if ever !!!
Simply, I've never laminated such a final size piece before and it ( at this point) appears intimidating to tackle / make.....and not to say, to finalise the output almost perfect, to perfect :0) !
Concerns : Gluing method / approach.
Then....flattening / ( say plaining) this +/- 26" rough width before the finished 25" x 13ft
In the past, all my experience laminating was/is based on smaller manageable ( to me) pieces... ( Biggest is in the range of +/- 30 x 96 or less with regular flat grain pattern)....this one, is new & different to me !
Thanks again, for any direct advise of those concern !
