[The Philpott]

Thankyou all. I am going to steam it over my spare mini-kettle (which conveniently, does not have a switch, so it can produce steam as long as i need it to. Knew i'd find a use for it eventually)

I will mount the fibreboard vertically in a workmate with some spreader boards, with the boiling kettle immediately below, then take up any slack by feel. If this works i can then clamp it between sheets of kitchen roll as it dries.
