to make corner peices get some foam pipe insulation and bend it (a little bit of shaping may be neccesary). poss put some bent wire in side it. lay up around it and then pour acetone over the foam and you have a rough corner peice. the other way is just to have a right angled corner by butting the tubes together and laying up over the join.

There all great ideas and have given me a lot to think about and options on materials as well.

I am a way off from making one but the ideas are there thanks to the forum members.

Many thanks

Robert
