Chris,
Thank you very much for your generous offer.  What would be a good way to
contact you about my project and I could get the wood from you.  All I have
around here is Home Depot and I don't think a 2x4 is what I want to use for
my first try.

Thanks
Bennett

Subject: Re: [HG] Building question

I am hard pressed to see pieces other than a peghead that would require
lumber more than standard 4/4 or 8/4 dimension, which should be readily
available at most places that sell lumber.  In the US, Woodcraft stores have
a pretty good selection, and they are in lots of major cities.  Also a
supply that is often ignored is hardwood flooring companies.

But the key to laminating is and has always been to keep voids from forming
in the laminates.  Use a thickness sander if you have one, or make certain
that your planer is set up well (planers are notorious for leaving less than
ideal mating surfaces.  If you have to use a large hand jointer plane to
make sure your mating surfaces are perfect.  I use water-thinned aliaphatic
(white carpenters, like Titebond, not white craft like Elmers) and prime
both surfaces with a thin coat, then when it is dry, I sand them level and
apply another coat of thinned glue, and glamp with call blocks working from
the center of the piece to the outside.  Good clamping pressure and clamp
distribution is critical.

The reason for this is that vibrations can break down glue joints, and where
there is a void there is usually some flex in one or the other piece that
has held them apart, an active force working in the laminate.  Vibration
from an instrument can start in one of these voids or pockets, and destroy
the glue joint from inside.  You can end up with buzzes and strange
vibrational dynamics if you don't have a good, void free joint.

You can, and I also suggest if you have access to it, use hide glue to make
your joint - treat it the same way, prime the wood surfaces with a thin
layer, then activate it with a hot, wet cloth, add a little more glue, and
clamp from the inside out.  Don't use the brown 'hide' glue in a bottle,
cook up your own, you can order it from many places.  Hide glue makes a
strong joint, and it helps to dampen the vibration effects in the wood
joints, because of the thin bond line, the deep penetration, and the
flexibility of the material.  There is a reason why hide glue is so revered
in instrument making - it doesn't get in the way of sound like other glues
do. 

But in all honesty, you should try to find single pieces of wood.  If you
can tell me what you need, I can probably round up pieces and get them to
you at a minimal cost (I probably have most of what you need in my shop).

Hope this helps

Chris Nogy
