Arvid,
I have seen the Otto site - he says it should be a plastic tube or at least insulated if metal. The one I made used Aluminium tube and I have to say didn't work as well as I thought it would.
I hadn't seen the 'instructables' thanks
Seems from the Otto site there are some sizes (or ratio of sizes) that are important.
