Hello and greetings to the group. (My apology if this posts twice, I am
having trouble with the server.)
I am embarking on a project and I have a question about glue. I believe
I already know the answer, but wanted to confirm.
Is there any reason that two boards glued face-to-face with tradional
yellow glue would not provide a strong enough and permanent bond for a
vertical load bearing member of a bed?
I am using air dried walnut from central Indiana to build a bunk bed
such as this one http://plansnow.com/bunkcloser.html
The plans specify using boards 1 and 1/16 thick but I can only get about
3/4" thick after I plane them. With that in mind, my intent is to glue
two pieces together to yield a 1.5" board and then plane that down as
Is this sufficient for a 20 to 50 year span and beyond? Should I
consider any different adhesive?
For the horizontal rails, there are a few thicker boards available.
The laminated result would probably be stronger, or less resistant to
bow then the solid board.
If your design can accomodate it, you might consider just
gluing/screwing a short flange on the underside of the 3/4" board at
each side creating a channel shape. Would cut down the weight and be
just as resistant to compressive loads.
Fine Woodworking- August 2007 had an excellent article on glue strength.
Even comparing to all the high tech adhesives, plain old wood glue won in
almost all categories. You should be in fine shape following your current
Yes. It is common practice to glue up 1" thick boards for furniture
legs. The glued-up legs are actually stronger and more stable than
one from a solid piece. Make there are no gaps (without any
pressure) between the glued up boards. If you can spare the time,
allow an extra day for the glue to cure before working it.
