making a bbq

[woodfarmer]

I have been machining a gas cylinder in the lathe to make a BBQ, sadly it keeps falling out of the chuck as I cant support the other end because it is too big diameter to be run whilst over the saddle. Somehow I need to make a long centre ??

Was surprised how thin the metal is barely 1/8th of an inch. (about 3mm in newspeak).

Can't visualise what you are doing but you might be able to adapt something from this idea.

Simon Hope sells a mandrel for reversing hollow forms. There is a photo of the tool & its use

Agreed, I was surprised how thin they are when I made a wood burner a little while back.
I used pub C02 bottle for the chimney and they are much thicker, approx 6-7 mm
Decent steel though.

No wonder burgers and beer are so expensive ...

I have a large gas bottle that I would like to turn into a burger but it just doesnt feel safe cutting into it. How do you go about it?

If you can get the valve off, fill it with water before cutting it.

Use a jigsaw at low speed and watch for heat build up. ie dont get it hot.
