Hello /diy/
I'm building a case for a vintage saxophone right now. The case per se is not that difficult, but I was wondering if you could help me with the interior design of the case. Usually it's fitted to form. I tried to create a formfitting shell by using plaster on the sax, wrapped in cling film. Suffice to say, it didn't work out.
What's a good material for a mould?
>inb4 fibre glass, I'll have to apply that on a musical instrument :/
Could I use plates of wax?

what is wrong with literal foam

I'd need to cut that in layers. It would then look blocky and amateurish.

Back in the day they just used a soft wood that was carved into shape and then covered it with felt or crushed velvet, etc.

You're an inspiration, anon!

I'll try sawdust, mixed with wood glue, that should do the trick! :-)
That should be also less work than carving.
Wrap your saxomophone in a plastic bag
Fill a deep box (cardboard or something disposable, larger than the hard case) with some expanding insulation foam.
You may need to put a standoff into the foam to prevent the instrument from sinking to the bottom
place instrument into the foam (you did seal it in plastic well enough didn't you?
fill the rest of the box up with foam
let it dry for a couple days
Get a foam saw and cut it out of there
Cover foam with contact adhesive, apply velvet or felt.
You could also go the dense foam method, then cover that in fabric. They make "pick n pluck" foams for customizable gun cases. It looks kinda plain, but again, you can cover it with anything you want. You're concerned about protection of the instrument should you drop the case.
Its not hard to do, big foam block and an Xacto blade you can get it carved in an hour for a custom look. Pic is a different instrument case.

I've heard that foam expands while curing, it might twist the delicate keywork. But viable for guns and guitars, I guess.
>pick'n'pluck/big foam block
I'll keep it in my mind. Thank you.

It does expand, but it won't twist or harm the keywork. Its also why you're doing it in an oversized box to trim down to better dimensions for the hard case. Seriously, if your dad has a can of it in the garage, or you're find spending $3 on an experiment, just go put a few test pieces in it and try it out.
You could just do a basic plaster casting of your desired shape, which you then use as the cavity for a spray foam job, followed by fluttering down Velvet or whatever.

We've reached Peak Great Stuff meme: someone actually found a way to make a serious suggestion with it.
1. get case
2. spray in expanding foam
3. layer fabric over foam
4. push in sax to make impression
5. repeat for other side
Get some of this stuff.

The blocks of foam that come pre-cut in to 1" squares are handy if you want to save a little time.

Just wrap the sax in plastic wrap so as not to get any foam on it.
