6″ Vertical Boiler Chimney Flare
I was relieved from duty with the ankle biters for a few hours today, when my wife took them to the local animal sanctuary. They petted a Tree Python (OMG!), and a Koala, and were entertained by the talking Sulphur Crested Cockatoos, one of which is aged 91 years!
Making the most of my temporary freedom I visited the workshop. Soldered the chimney support to the smoke box roof, and made a chimney flare. It probably has a more technical name, but when you see it, you will realise where it goes.
