WHAAM - CRAK!
« on: November 18, 2020, 07:59:42 am »
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
Arnold

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!!!

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.

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

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...

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
