Thanks, Hitch. I'll bear your kind offer in mind. The garden thingy may be more viable over the Kent to Plymouth distance than the shower rail.
I was planning to make a mock up of the shower rail using 1/2" copper pipe because it needs to follow a very precise shape (and not one that is easy to illustrate and measure). This being the case, sending the template in the first place adds to the cost. Nevertheless, I'll not rule it out entirely at this stage.
The garden thingy, on the other hand... I have a pond which is surrounded by a short fence. I want to suspend a net over it to stop the leaves falling in. I propose to screw hooks in to the (short surrounding fence) fence posts and attach the net via some bungee cord. Then, I want to raise the centre of the net so that the leaves fall off - a bit like a tent. It's the centre that needs the metal work. I want a rod that slots (so it can be removed) in to a bracket on a fence post (which is part of a nearby taller fence) and then curves out over the pond so I can hook the centre to it. A bit like fishing rod. I'm picturing a length of galvenised rod with a hook on one end. I anticipate a degree of flexability so that the net is held up but the rod is not so rigid that it does not allow some give. The only issue that I am unsure about is the carriage for such an item. It would be quite long (2-3 metres possibly) which I think means that it would have to be a carrier rather than Parcel Post. The other thought that has just occured to me... Perhaps I could get hold of the rod and bend it myself, thus only needing a suitable galvenised bracket?
Would be grateful for your thoughts.
Thanks again.
