Turn it on, then another 1/4 turn is fine. You don't gain 100HP by having it open all the way.

Went through this with one of our workers yesterday as a matter of fact. She changed the bottle, but still the fork wouldn't start. One look at the valve told me the connection wasn't on properly, therefore no matter how far you turn the tap on,, it won't work. She'd opened it right up, although it was easy to undo again.

I explained to her the possibilities, and my experience the other day of fitting a bottle which had the tap already open.
Decsission time,,, do you go for the tap, or try and undo the connection again. Of course, connections always get jammed when you least want them to

Gas burns hurt like hell.

Hmm I think the ball is in my court here, took a while to get back to it.
Struggling to come up with something in keeping with the 'Engineering Marvel' theme rather than just a mystery object, here's an engineering marvel that I utilised last year.
This image is straight from Google so I will consider an image search to be cheating.

I've seen this before. There was a docco where a lady was cycling and kayaking along it.
Can't remember the place name though.
It's a navigable aqueduct, but couldn't tell you where it is. Thinking UK.

It's an aquaduct, in the UK....is it one of Brunells?

It's the Pontcysyllte Aqueduct across the River Dee in North Wales built by Thomas Telford.

That it is.
We crossed it twice in a rented narrowboat last year. A cast-iron trough on brick arches that carries the Llangollen Canal 307 meters over the valley of the River Dee at a height of 38 meters. Completed in 1805 if memory serves.
No railing or parapet of any kind at the side of the aqueduct, from the steering deck of the narrowboat you look straight down over the side. Was a highlight of a very enjoyable week.

I think I'd crap myself...

Don't like heights? I'll look after the 101 for you

I think you'd love it! Narrow boating is pretty cool.. You watch the world go by whilst putting along at 4mph, usually with a twin pot Lister, Ford Transit or Land Rover 2.5 d rumbling away underneath!

Its not the narrow boat that would stop me, but that 300 metre drop right next to the boat! Look it up on the internet and marvel at the bod driving the boat with just fresh air under him!
