@Jonnyb. So how much will a tradesman, making a living wage, charge someone to unblock a vacuum cleaner tube? A frequent 'repair' for us. If any gluing needs doing, our repairers usually take the job home.
Of course they are going to say to have it repaired by an authorized agent. That's how they make their money. If it's out of warranty then anyone with a bit of sense can repair them. They are built up in China from generic parts. so are easy to source
I made one of those under the guidance of my best mate who was/is a highly skilled restoration carpenter. We decided to split it in half. I did the top and he did the bottom. I was told to use hand tools and took me hours. He just threw it onto a mortice machine and did it in five minutes!
