    If you really must have a clear tube best to go for polycarbonate, perhaps:

    Can anyone assist?

    I have recently obtained some pieces of transparent plastic of unknown provenance.
    One piece is known, it has a Lexan sticker on it.

    Does anyone know a sure fine way to determine if my other sheets are acrylic or poly-carbonate.

    I already know from bitter experience that Acrylic cracks easily and I have some more bulkheads to fabricate.

    regards

    Acrylic -- you can't cut it with a knife, it will chip. Heat it and it will smell 'sweet'

    Lexan -- you can carve it with a knife.

    Nice Video - anything that survives those tests, I would trust.

    I have finally decided to cut off a sample piece from each sheet and then try to carve some slivers off each followed by a gentle caress with a blowlamp and finally an intimate introduction to a 1 LB (imperial) ball peen hammer. Methinks that safety goggles would be advisable...
