I made the funnel head out of a 100 mm PVC pipe, have found the stuff very handy when you combine it with a heat gun on low. Did take a bit of time to shape but I am very happy with the outcome.
The ripple section is removable and made out of alloy flashing with self adhesive furniture felt, thought it would do the trick until I sourced some of that blue mat. I am on the north side of Sydney, so a trip up the coast is not out of the picture although I'll corner them at Belrose and tell them they are being unreasonable, thanks for the heads-up.
