Hi all
I am wondering about becoming the scourge of my neighbours(*) and making
a garden set of tubular bells.

I'd like to find a source of suitable metal pipe. It should be:

- of decent diameter, say = 20mm
- non-rusting (within reason)
- cheap

Scaff pipe is a bit too hefty, and something like 28mm Cu pipe is a bit
pricy. Any thoughts about something in between? I'd probably need a bit
less than 10m.

(*) not really, it would only be for when the granddaughter came round...

Thanks
