Need help with quater saw cut

I am making a guitar body with a 20x14x2.5 inch block of wood. I want
to cut it down the center (quarter saw ?) so that I have two pieces
that are 1.25 inches thick. I will then hollow out the sides and glue
them back together.

I have asked three local shops for assistance but none have been able
to help since they would need a bandsaw with a 14" throat(?). Is it
unreleastic to try to find a bandsaw this big ? Perhaps I should just
route out one side of the block, and glue a back on to it.

Any advice appreciated.

In my very limited luthiery experience, that is not how you make a
guitar body. James Jones here in Bedford has a 12" rip capacity on his
Delta 14", but he resaws for the sides, and bookmatches backs and
front. I doubt very much the method you mean to use is going to supply
the resonance you need to make the guitar a pleasure to play and listen
to.

Hit google for "luthiery" or just take a spin through the Grizzly
catalog (on or offline), or check out Stewart-MacDonald, where there
are numerous stringed instrument building kits that ease the pain of
getting started by a considerable amount.

The word you want is resaw.

>throat(?)

Cutting height. Throat is the horizontal distance from the blade to
the support that holds up the top.

12 inches is sort of a magic number for resawing. A typical 14"
bandsaw with a riser block can resaw 12 inch wide boards. Any more
than that and the bandsaw gets into the couple thousand dollar range.
Keep looking though. I'm sure there are shops that can do it.

This is called resawing, if the grain is perpendicular to the cut as
I think it will be for a guitar back, it will also be quarter sawing.

It can be done with a hand tool called a resaw. Resaws are typically
frame saws. A small one is illustrated here:

http://www.hyperkitten.com/woodworking/frame_saw.php3

Yours will have to be bigger, but the same approach applies.

If you can make a guitar, making the frame saw will be a piece of
cake. BTW, do not use curly maple for the frame, DAMHIK.

There is also a newsgroup devoted to lutherie in the rec.music
or rec.crafts hierarchy.

Thanks all.

>> Does that mean the finished guitar is 28" wide?
No, the guitar will be 14" or less wide. My plan was to split the
block (as you would open a book in the middle) and hollow it out then
glue the sides back together. But I am hearing that this may not be
such a good idea.

This is the second guitar I am building, and it has some odd options
(headless - no headstock, and the neck is fanned fret). I was going
for a chambered semi-hollow sound. I will re-think this body idea.

Mikes right if done correctly will improve sustain
here's a site with a pic of one such body

http://www.scogo.com/design.html

also as mentioned before check out:
rec.music.makers.guitar

you could make the guitar with bookmatched top, chambered middle( width
could be glued up) and bookmatched back

If this is your first guitar, maybe building something like a Strat
copy would be a good way to get experience. The problem with making
it hollow, and then gluing it together, is that your electronics will
then be impossible to repair without cutting the guitar back into two
pieces. Also, a hollow chamber of enough size to work in, will do
dramatic (bad) things to your sustain...unless you're going for the
semi-accoustic sound.

Also, if I understand what you're saying, you need to "resaw" this
with a 14" height, Does that mean the finished guitar is 28" wide?
I'm not clear on which dimension you're cutting here.

Right. Decide if you want cover plates on the front, or on the
back. I like 'em on the back, so you can have the pretty wood on
the front. The back _will_ get scratched up, so might as well
have a hatch under the pickups and under the controls.

Take a look at how Rickenbacker does the semi-hollow bass body.
Loverly sound, but more work than I'd take on for a second guitar.
Maybe make this one a nice fiddleback maple solid body and get
more experience? But either way, have fun with it.

Interesting. Who built it? I'd like to read up on it.

Well - not quite Dave. Chambered guitars exist and they have great sustain.
Not semi-accoustic either. Raw electric. I know - I have just such a
thing.

Almost - but not quite. Guitar tops are usually bookmatched (if a fancy
grade of top is desired), but those tops are typically only 1/2" thick and
go over a body that is somewhere around an inch thick and is one solid
piece, not bookmatched.

I use a chainsaw for doing cutting of trees into slabs, then plane them to
the thickness I need.

Guitar tops and bodies are usually bookmatched, which means there's a seam
down the middle and the halves are essentially mirrored. In other words,
you resaw your piece, and then open it up like a book.

So it sounds like what you would want to do cut your piece in half to have
two 7" wide pieces, then resaw those pieces to 1.25" thick, and glue up
bookmatched halves for the top and bottom.

You might ask the guys at rec.music.makers.builders.
There are some very experienced guitar guys there. They will likely
have some good suggestions for you but could also recommend a re-saw
service if you need one.

Mine is from Terry C. McInturff. Here's a link to the model I have which
has the tone chamber. Not all of his models do.

http://www.mcinturffguitars.com/06-Guitars/GloryStandard/GloryStandard.asp

These guitars have sustain that goes until forever. They play nicer than
anything you've ever picked up too.

I would bet there is SOME woodworker in his area that have a Bandsaw
that will do 14+ inch resaw. However, how to find them is the
problem. Posting in the MiniMax Yahoo group or the Laguna group would
probably turn up some owners - most of whom would be easily convinced
to do this for a small fee or gratuity
