: Plastruct butyrate tubing
: des December 23, 2019, 02:33:22
Hi all

I am looking for a material to make some derricks - but it needs to be hollow so I can pass some lighting wires through.  I thought ABS would be appropriate - its far more rigid than styrene tubing, and much easier to work with than brass.  And it's easier to bog up oversize holes and fill gaps etc.

Anyway, I ordered some Plastruct ABS tubing, but have been told that it is not available.  And nor can I obtain any in the size I need from industrial suppliers here - at least, none that I have been able to identify.

My local hobby shop guy suggested using Plastruct's butyrate tubing.  But I haven't used it previously, and I can't find any specs for it.

Has anyone used this stuff?  If so can someone please tell me whether this stuff is rigid, or semi-rigid (able to be bent with heat or similar), or non-rigid (like styrene tubing).  Does it take paint well?

I've looked at various alternatives - acrylic (generally too brittle), polycarbonate (too expensive in small quantities), PVC (can't get it in a small enough diameter), etc.  It has also been suggested to me to try polyethylene or polypropylene - but both are too flexible and don't take glues very well.

in the past i've used styrene tubing with a brass tube insert. Or several brass tubes that will fit inside one another. You won't bend that.
It's fine if you don't need  tapered mast.

Hi Des
What diameter of section are yoi looking for? I know you live in Australia but I use EMA model supplies who are bssed in South London here in the UK. They've got a website which shows all their range of tubing etc, it might help to see what is available.

Hi Kevin - thanks for that.  I've checked the website, and they have the size I want, in stock, and at a price which seems reasonable - it all depends on shipping costs.  I'll contact them  in the new year and try for a quote.
