Now you can tell how much time I have on my hands.............I've made a
homemade guitar case out of 3/4" plywood. For future reference....1/2"
plywood would work just fine and be quite a bit lighter.

Anyway the structure is complete....now I need a way to pad the inside and
make a comfy place for my Epiphone ET290-N. Does anyone have some
experience with foam in general and expanding foam in particular?

While researching the subject (and after visiting mcmaster.com) I found this
interesting site...check out some of the other pages too if you have time to
burn.........

Planning to drive a truck over it??

Don't know much about the "foam in a can" stuff, but I'd guess that
you'd want to build a form for the shape you want, maybe coat it with
wax paper (so the foam doesn't stick) and shoot it around the form.

You could also run down to Homey Depot or Lowes and get a big sheet
of styrofoam insulation (the stuff they wrap houses with) and cut the
shape out of that. Then just glue it into the case, cover it with
some nice, plush, velvety crap, and call it a day.

3/4"!!?!???!?!?!?

Did you put wheels on it? ;-)

BTW, I saw that one of your GJr clips made it onto analogman's
website. Congrats!!

I wouldn't use expanding foam, because there is no need.

Expanding foam is best when you can't get to all the nooks
and crannies, and in this case, you can. Expanding foam may be
more work anyway...I worked in a factory that made specialized
packing...FWIW.

I'd use slab foam...maybe 1" on the bottom of the case
and an "outline" bed of an inch or two...easily cut with a
knife..then cover with some kind of reeeel classy velveteen.

I have to agree... 3/4"...??!!!!!

YIKES..!!!!! :-)

Since you have the time...

How much clearance do you have on either side of the guitar,
inside the "case"...???

I would be inclined to use a medium-firm pillow foam...
and cover it with some furry material...

IIRC.... BE VERY CARFULL THAT WHATEVER IS INSIDE
THE CASE AND COMES IN CONTACT WITH YOUR GUITAR
IS NOT, REPEAT NOT, SOME SORT OF VINYL PRODUCT....

I seem to remember that vinyl EATS guitar finish...

If you can locate an upholstery supply company... they carry
foam for cushions in different thicknesses and density... some
can 'cut to spec'....

There is a place in Philadelphia that takes delivery of pieces of
foam, one solid piece, as tall and wide as the inside of a
tractor -trailor..!!! they have a giant 'band-saw' that they slice these
big pieces into mattresses, etc... pretty wild...

I'd be more than a little leery of anything involving organic solvents and
guitar finishes in close proximity with one another. I once used some red
rubber coated broom hooks to make a display rack for several guitars. It
worked great, except that the plastic/rubber coating on the broom hooks turned
the finish on some of the guitars to goo. Now the hooks have surgical rubber
over them. If there's any way of pretesting the materials you plan to use, by
all means do it.

Fender cases seem to be made of 1/4" plywood. Not that I've ever
dissected one. As several people (and you) have pointed out, 3/4" was
excessive, but 1/2" probably is too. When you add a guitar to all
that weight, you won't like the 1/2" idea much either.

I'd probably scrap the 3/4", and start from scratch. And take a look
at how the rectangular cases from Fender are built. I recall someone
setting an SG down in my Tele/Strat case years ago, and it looked like
that case's design would have worked perfect with an SG.

There's some padding in the top and bottom of a Fender case, but
there's not foam molded to the guitar shape. The neck is sort of
cradled, I think around the 5th fret, and then there's a padded piece
on the cover that holds the neck in place.

I've considered building a case before, but it'd be too much work.
I'm impressed that you're building one.

Hey ERic
Go to any upholsterer in town and ask to look through their sample books. Pick
out a nice crushed velvet fabric to match your guitar color. And ask about
their high density foam. Very stiff, yet gentle. Put 1 to 1.5 inches on the
bottom. Make a cut-out section to fit your guitar and put a piece up in the
lid. Cover everything with the fabric you chose and you're all set, goin' in
style. As for the 3/4"...nice...;-). Idiot-proof the sucker. No tellin' what
kind of Bozos you'll meet at gigs. BTW, fabric of that quality goes for about
$25/yd at good shops. Its usually 54" or 60" wide.

Good luck

You can get that spongy foam stuff at places like Wal Mart. Cut to shape
and glue it in. I once made a guitar case out of 3/4" plywood - it was way
to heavy, but you could drive a car over it.

Be *very* careful what kind of foam you use.
Some foams will react with the lacquer on
your guitar. You *don't* want to see what .

3/4''! wow that's heavy. I generally use 3/4 pine for the sides and 1/4''
birch for the top and bottom.
Even the foam that claims to be 'minimally expanding' expands lots. There is
some new stuff by DAP which seems to do as it claims.
Care full I would not use the guitar as a mould.
I used to get ridged foam and cut out the shape then French Fit the axe. After
missing room for travelling gear, like fresh sox, Im switching to cases like the
early fenders. Closed cell sleeping pads and fleece in side. Peace Chris

Cool, thanks guys.

Like I said, I have time but had to keep costs down. I had a sheet of 3/4"
that was laying around ....that's how I ended up using that specific
material. The case with hardware weighs 18 lbs., three times as much as my
Strat's case. But even with my 5 lb. Epi it should be managable. I'm
pretty sure I could drive my 1/2 ton pickup over it with no
problem.............I consider it my small contribution to the Anti-Gig bag
movement.

Funny how that analogman thing happened...one of your other happy GJr owners
has been talking with him and asked me if he could send the clip as an
example of a tone he was shooting for.............cool!

I'm thinking of maybe building a head enclosure for my GJr and taking it out
of my "Nelocette" combo cabinet. Hmmmm, I have some leftover 3/4" plywood
around here somewhere.........I'll have to make a new chassis for the
Velocette to re-deploy it but that's not too big a deal. Then I can use
that for a 2xEL84 amp.......... Hmmm... just thinking outloud.....have a
great rest of the weekend!

You can get upholstery foam at a fabric shop. It comes in various
thicknesses. Get three blocks, one the same thickness as your guitar and
the other two each 1/2 the thickness of the remaining space. Glue one to
the bottom and one to the lid. Place your guitar on the guitar-thick
(OK, it's not really a word) piece and trace the shape of your guitar
onto it with a marker. Cut out the silhouette with an electric carving
knife and glue it in the case. I recommend spray adhesive.

Hope this helps.

That brings back a bad memory. I lost a Yamaha FG-512 to a 1/2 ton
pick-up truck once (tire ran *right* over the sound hole). Cheap
(standard) cardboard acoustic case. Now if I'd had one of your cases,
it probably would have stopped the truck. (Wheel chocks, anyone?)

Hold on there a moment... how did you get the chassis out of
the Velocette ? I can't get the rear of it (backs up to the baffle) to
let go. The whole thing wobbles like a loose tooth but the back of the
chassis won't come out ?

There is some kind of sticky foam stuff on that edge of the chassis. If it
is like mine, it will come out with a bit of encouragement.

Although I applaud your initiative, I have to wonder if the time needed to
do something like this doesn't more than offset the fairly modest cost of a
factory-built case, especially used. However, camera shops and sometimes
luggage stores sell nice thick sheets of high-density foam pre-cut halfway
through into one-inch squares to make it easy to remove the shape of what
you're trying to protect. When you're done it will look like hell, so then
you glue some plush material like velvet over it, and there you go, you're
ready to call someone to help you move that case. ;-)

I would usually agree with the cost issue but I have been on layoff for a
few months now and the $205.00 a week maximum benefit (before taxes) that
the state of Arizona sends me is SUBSTANCIALLY less that my usual income.
It's the first time I've collected unemployment since the early eighties.

So I got to feel creative and use up a few things that were just laying
around the place. I've got about $9.00 in hardware invested and maybe
another $10.00 in upholstery foam (I found a local source and will be
stopping by there today).

The case is for my backup guitar...will only be going from house to truck to
gig....no hitch-hiking across the US with this mutha! (God, at least I hope
it doesn't come to that!!!!)

Have a great weekend.....
