yes straight out of the kettle. the other problem was that my sink/washing up bowl wasn't quite big enough and i couldn't quite fit it all in.
when i snapped mine, i was being a big, clumsy, fat fingered idiot.
i snapped the bit that's closest to the last screw on the top horn or a precision, the really thin bit next to the cut out for the neck. it was my own fault and i was just applying a bit [i]too[/i] much pressure to it to see if it was soft and it turned out not to be - ping.
up until that point the tea towel/hot iron/two bits of board/stand on it for 5 minutes/check and try again, was working really well. i had two offcuts of an ikea shelf that i'd shortened to fit into a gap in the house and they were ideal.
I was sure i'd started a thread on it which had some useful advice, but i can't find it.
