I see you have got a solution for the moment.

PVC pipe will eventually shatter - ABS pipe will normally plastically deform under pretty much the same loadings, and for most of the expected loadings may not crush entirely, especially if internally packed with bubble wrap. If you can only get blackpipe, then painting may be an idea.


Rowan,

since you are a guest, I cannot PM you - I have a couple of small Piano accordions that currently live in small suitcases that, depending on the cost, might prefer to live in such a case - would like to be able to contact your brother.

I had endless hassle trying to find a suitable case to carry my whistles, especially the Low Whistles - I finally found a 'sports bag' in a fairly rigid form made of flexible 'woven' plastic that was intended for carrying modern wide head tennis racquets.
