Tornado

We were using water treatment on the KWVR in 1970. I always assumed all railways did the same?

 

SVR no longer use treatment as a standalone. We have Reverse Osmosis plants at KR/BH that mean we put just about as cleaner water as possible in. We occasionally use Soda Ash to balance the levels

 

It was my impression that most of Tornado boiler problems was physical and not chemical.
3 inches between outher steel and inner cupper firebox plates with screwed stays between is tolerable to ca 250. lbsi .
For welded stays between steel to steel , 4 or 5 is much better but give sligthly less grate area.

 

Please stop, it's just childish. I understand people have concerns but if you want them taken seriously petty insults like this don't help.

 

Fair cop, point taken, got carried away, I’ve edited my post . It was just very surprising to see one of the actual workers featured in a Trust good news video.

 

There's a contradiction there I think! The barrel couldn't have been paper-thin when it was last steamed.

 

I believe the change to injectors was more to do with ease of maintenance and usage, particularly when visiting heritage lines as it was thought that there was less benefit to be gained from a large and complicated Exhaust Injector over the Live Steam injectors crews would be more familiar with, which are both smaller and simpler to repair/repace cones.

 

I'm afraid it could well have been paper thin. I've seen a number of things which have suddenly come out of ticket following a well aimed screwdriver to a vulnerable location. The reality is that it doesn't actually take very much metal at-all to keep the steam where it belongs - you'd be supprised how high a pressure a bean tin will withstand before it finally goes bang.

These days we are generally better at finding thin bits before they reach this sort of point (UT thickness testing is pretty universal), but there are still occasional horror stories when we start overhauling stuff that was recently in ticket and we find it was like tissue paper!

Over the years I have put a caulking chisel through a fire box crown, a screwdriver through a smokebox tube plate and seen grooving above a foundation ring on a std gauge loco you could put your thumb into, less than 1/32" thickness at the bottom of the groove. I had been driving the loco the week before.
So I agree we are better at spotting things with modern techniques but un spotted things can still get by the best of us.

 

That's because the pressure is applied over a larger surface area.

 

Interesting though it is, isn't this getting just a wee bit OT?

 

Someone else who doesn't know what landscape mode is!

 

To be fair, nearly everything filmed for Facebook makes more sense in portrait as that’s the format most people will watch it…

On their phones for anyone wondering ….

 

Either that or they have turned their tellies at home through ninety degrees... here's an idea - let's make videos in 21:9 format and then turn them through ninety degrees. Hey presto, we've re-invented Baird's original mechanical television aspect ratio (which was 3:7)!!

 

That rather assumes that people are using a laptop to consume video. But most content is both produced and consumed on mobile phones, and the natural way to hold them is portrait mode. My hunch is that - outside the rather niche world of grumpy railway enthusiasts - the vast majority of video content consumed now is done in portrait using a phone, so it makes sense to produce it in that format.

Disagree. Show me television programmes that are produced in vertical formats.

A lot of people watch YT on their television sets and it doesn't alter the fact that both film and television are made in landscape mode, which mimics the eyes' natural field of vision. I know people who have produced material for TikTok using conventional film and television equipment and it is a right royal pain in the bum, they tell me.

 

When you're taking still photos with a normal camera you use portrait format for portraits (surprise!), landscape format for landscapes (ditto), and whichever seems more suitable for other subjects. If you then view those photos on a phone you turn it the appropriate way round. Why should videos be different?
(Apologies for continuing serious thread drift.)
