Making a Polypropylene Cylinder?

[aamcle]

Its a bit obscure but somebody may know or know were I might get help.

In want to make a cylinder 30 cm (1ft) diameter by 100 cm (3ft) long out of 4mm (1/4 inch) polypropylene sheet, I'll weld the join and it needs to be round!
If I can't do it with PP I could try thicker HDPE.

Any help would be very much appreciated


Thanks. Aamcle

Google "welding polypropylene" and some nice stuff comes up. The welding looks tricky.

You'll also need to heat the 1/4" thick sheet so you can curve it around a surface to make it round. You'll need a 48" x 48" sheet unless you can find a scrap piece that gets you to around 38" x 36".

What are you trying to make? Have you looked for 1ft diameter tubes anywhere?

I've looked but they are very expensive in the uk

There are a whole range of things I'd like to make, I'd prefer SS but there is no way I'll ever weld it.
