Have one of these wort chiller, which works well.

However i use it in a 33 litre pot, so if i do any more than 18 litres of wort it submerges completely. Which is a but rubbish.
Yesterdays brew i cable tied it to some conduit across the pot. But only half of it was in wort so took forever.
Thought about making it height adjustable, so i can set height before i drop in the pot.
Possibly using something like some more copper pipe as legs.
Any ideas would be great, as no idea how to attach it or make it adjustable.
