Bede, I should just like to let you know that your e-mail has given me the clue = I think I needed to sort out my Elidir boiler=2E I was working in the wrong plane and one of my major problems was getting the solder to flow around a curved surface and stay there=2E The way you did the outside of the firehole ring is the way to go forward with Elidir, that is (whilst its is a lot bigger and I am working on the inside) I should stand it upright on the backhead and then the surface I a= m working on becomes horizontal and thus a lot easier=2E Brilliant!
