Thread: Steam box

I have tried PCV pipe and found it sagged too much when heated. (This was the white pipe - perhaps it would be better if you can get the higher heat resistant grey stuff, but I couldn't find any.)

I then tried exterior plywood with much better results.

Hi James.

Steam boxes are very easy to build, once you understand the simple basics of what is required.

You are only building a contained tunnel for the steam to work on the wood inside.

I suggest you look at some boat building sites, to get a few ideas for what you need.

PLASTIC. NO.
STYROFOAM. NO WAY.

Your structure needs to be able to support the heat generated, plus the slight pressure you will apply to your steam application. (not much).

I just GOOGLED your enquiry.
Heaps of info there.

Paul.

Thank you guys, I'll go for plywood then.

Starr: I've read about the "sagging problem" with pvc. Some solved it by installing the pvc pipe onto a wooden beam. But I guess a steam box with plywood is more reliable.

Again, thank you, I'll let you know how it turns out.

15 metres
what are you making?

Oops. I understand your reaction, mate. Should have been 1500 mm.

that makes me feel a little better

what are you wanting to make? I'm just curious, I have no knowledge to impart in this area

I have used 100 and 150mm PVC - the cream stuff - without problems.

Cheers
