Deep perversion

[SimonMac]

As a geek and a scuba diver this gets two thumbs up from me, fascinating.

I have now. It looks dangerous.

The chicks dig it.

I used to do it, at least one helicopter part required a tube to have the end 'spun'.

When it became apparent that no-body on our team knew how to 'spin' they sent me over the road to watch a guy making lampshades from sheet metal.

Something has to 'give' to stop excess heat so when spinning soft material you use a hard tool, when spinning a hard material you use a soft tool... Halcyon days.

The last bit of spinning I saw was on one of Fred Dibnah's programmes. Clever stuff indeed.

Have you ever seen any videos of metal "spinning"?

Now that is an art!

Nice to see that the product is properly lubricated prior to the deep draw

Interesting the way they curve the tops over.

I've never dived but i always thought scuba tanks would be aluminium

Ah that's interesting, I always wondered how things like that were made, I assumed it was some sort of a press.

Yeah, I didn't understand that bit. She said something about 2 degrees of wall thickness?
