The Burner has been treated with "Shot Flon" to make the antique finish
A superb finish.

Thin wall pipe and 3 jaw chucks do not play nicely together ( don’t ask how i know )
I have purchased a 6 jaw chuck that is a big improvement but still a bit risky

To Stoker:
Yes - I know - never span a hollow body in a chuck - this and 100 other rules in your workshop
but sometimes a little lazy man in your Brain persuade you - and it can work 99 times....and then "Bratatatata"
(I like the terms by Roy Lichtenstein)
To Jim:
The Burner has been treated with "Shot Flon" to make the antique finish. It is a sort of
Browning chemical - you will find "how to make" videos (funny) https://www.youtube.com/watch?v=bOp9Fwr3lYo
and there are many more...

Oooops...

Looks very nice, do you give it an antique look?

ouch! I've had a few parts come flying off both my lathe and milling machines, doing things I should have known better. I use parallel bars to evenly align things in the lathe chuck, and forgot to remove them before starting the lathe - Won't do THAT again. We could start a thread for sure on stupid mistakes we've made. Glad you survived and the replacement burner looks great.

Ooops!
You got it looking good in the end though 8)

Loading an assembly by clamping on a thin walled hollow space while trying to make a peripheral cut produces a whole lot of poorly supported force. Seems I've learned this lesson somewhere in the past myself. Very glad you survived the ordeal with nothing worse than a lost burner.
A file may have worked better at removing material in that set-up, as it is less prone to dig in and grab, but a slow gentle approach would still have been needed.
Very nice burner by the way, I'd say it's about perfect for that engine ..... well done!!!

I have an upright Märklin in excellent condition - except there was no Burner!
I made one entirely from Brass - and the Mushroom from a 44.Magnum Case (as shown before)
After trying to fit into the Märklin, the diameter of the floor was 1 mm to wide and I decided
to clamp the already finished Burner to my Lathe. And it happened - it just flew in parts trough
my workshop - I was very much lucky that I was not hit by one of the fragments. Sometimes
you should follow the inner voice!!!
After making a new body and soldered all together the Burner was finished again (2 hours!)
And it works fantastic - enjoy
