Hi Paul,

I had the same thoughts as Charlie wondering how that flange was made, thought it must have been machine rolled as it was so good.  But 2 nuts and some threaded bar, that is amazing!

Kind regards
Ade

Agreed!

Very resourceful.

Great work Paul.

How did you make the flange on the top?

I used a couple of machined "nuts" on a threaded 3/8-24tpi rod. One nut was machined to fit into the
Bottom of the tube to be flared. This was made from 1 inch 12l14 steel a portion was turned down to fit
Into the tube. The other nut was turned with a 45 degree taper with a short section turned to fit into the tube ahead of the tapered portion of the nut. Both nuts were threaded to fit the rod. The tube was slightly chamfered at the end to be flared. By placing the nuts at each end of the tube and turning the top nut with a large wrench while the bottom nut was held in a vise the flared end was produced.

That is a fine piece of work Paul, & more robust than the original I'm sure , it'll outlast us all.

 :[attachimg=2]I'm glad to say my B30 Empire chimney is finally Finished.
I think it turned out well, although it's slightly taller than my original one by roughly 2 mm.
I used 3/4" stainless steel tubing purchased from McMaster-Carr. This was a little difficult to
work with, but as you can see, it polishes to a chrome-like finish. The base part was made from
brass and I nickel plated it to match the stainless. I features my own design safety valve without
the screw and nuts of the original. I'm still waiting for the correct length springs to come from
McMaster-Carr to complete that.[attachimg=1]
