I can't find anything on this subject, but if there is something useful I would appreciate being directed to it.
My 15 year old Selmer case, which is in otherwise very good condition, is starting to sag in the area where the mouthpiece resides; i.e., between the mouthpiece and the two keyed sections (photo attached), where the styrofoam (?) has apparently collapsed.
My repair tech is not interested in trying to fix it so I have nothing to lose, except some time, in trying to repair it myself. I am considering using the insulation foam that comes in a pressurized can to build it back up but, before I do something irrevocable, I would like to know if, and how, anyone else has solved a similar problem.
Thanks for any advice or ideas.
Hans

Hans,
I wouldn't recommend spraying foam in there, instead, I'd get some styrofoam block material or medium-density foam (such as is used in packing) and insert it through a slice in the fabric (which you'd make with a razor blade in the most inconspicuous spot available). Afterwards, seal the split by gluing on a thin patch of matching velour using a bit of fabric adhesive (usually comes in a spray can, 3M makes a good one, for example).

Hans,
I work at a museum and pack lot of artifacts for travel and exhibit. We have tested a variety of materials for off-gassing that can affect metal, such as clarinet keys and rings. We use polyethylene foam "Ethafoam", 3M 77 spray mount and clear hot melt glue. The "77" off-gases quickly so if you give it a few days to cure before closing your clarinet up in the case, it shouldn't cause any problems. Don't over do it with glue if you don't need to. I am not sure where you can get small quanities of Ethafoam, unless you have a friend in a museum somewhere. I do see it in electronics packaging sometimes.

If the case is not missing too much styrofoam you could glue the thing by injecting the white glue for wood through the fabrics, where needed. The glue itself is liquid, and u have to use injection needle.

Thanks for all of the ideas above (and BobD).
I will take pictures as I work on this problem in case they might be useful to anyone else.
Regards,
Hans
