RMweb Premium J. S. Bach Posted June 24, 2023 RMweb Premium Share Posted June 24, 2023 (edited) When the Kitty Hawk pulled into Sasebo for a "show-the-flag" visit back in 1970, all I saw was one three-axle switcher! I did visit the local passenger station but for some reason did not venture out to the platforms. And none of the shipmates that I ran with wanted to go anywhere! 🤢 So I never got to Tokyo, or anywhere else for that matter. EDIT: The same thing happened when the Hawk made the same kind of visit to Hong Kong. We did make the Victoria Peak incline and the trolleys along the water front, though. The disappointment was not going to the mainland and the train to the border with China; I seem to recall that there was a viewing platform to look into Red China. Edited June 24, 2023 by J. S.

RMweb Gold Happy Hippo Posted June 24, 2023 Author RMweb Gold Share Posted June 24, 2023 I have been mainly bimbling today. First I tried some proper logistics and tried to stow Pantmawr North into the back of the BMW. It fits, providing it is stored in what would be referred to a freight terminal configuration, where only Passenger services continue off scene at one end into a small 'hutch'. Then I went a tidying, although that is a bit like Andy and his painting...It never stops! Finally, the neo magnets I bought arrived this morning, and I have just finished a bit of bodgery* to create a magnetic shunting pole. Nothing new in this, but having tried it on a selection of wagons, 7mm scale three link coupling and uncoupling is now a breeze. * With such small bits to work with I really do need to get myself a proper collett chuck for the lathe. (I have one for the milling machine and it's brilliant.) 8 2 Link to post Share on other sites More sharing options...
RMweb Premium SM42 Posted June 24, 2023 RMweb Premium Share Posted June 24, 2023 (edited) Despite had dark clouds over SM42 Towers, it has remained dry. I'm currently waiting paint to dry before the second coat goes on and have started on a job I have put off since last year. Namely, to cover the ugly looking gas pipe that was installed on the outside of the house when the boiler was upgraded. This I am doing using a length of left over guttering from the construction of the east wing, which I will screw to battens attached to the wall either side of the pipe. Now just as Mrs SM42 returned home I found that I had run out of 2 inch no 8 screws for attaching the battens. The plan was to head out for supplies, but Mrs SM42 declared she needed to go shopping, To save locking up the house I drilled and plugged the last 6 holes in preparation and planned to head out on her return Fortunately as I was tidying up my tools I heard a rattling in my pocket and found 6 screws that had obviously fallen out of the pack I was using earlier. I had six holes and six screws. Result. Somebody is obviously watching over me. Andy Edited June 24, 2023 by SM42 10 2 Link to post Share on other sites More sharing options...
RMweb Premium SM42 Posted June 24, 2023 RMweb Premium Share Posted June 24, 2023 The gas pipe is now covered. I now melting slowly in a shady spot in the back garden considering my next move. Meanwhile Mrs SM42 has announced we are off to the pictures tonight. That second coat of paint might be going on around midnight it seems Andy 12 Link to post Share on other sites More sharing options...

How is it even possible to run up such a deficit, making welly boots? I assume that loading a company with debt while downgrading the product by cost-driven out-sourcing has an in-built limitation? I'd be curious to know what wellies are favoured by RMWebbers? I currently have a pair of Rockfall work wellies (these, or Buckboots equivalents are pretty much standard for onshore drilling), a pair of those bright yellow Dutch gas company ones (anti-static for working in gas plants) and some cheapies from Arco for gardening ... I looked at my wellies recently and it seems they were made in Portugal. They are holding up very well. I've had them for yonks and it's more than likely I brought them from the UK more than forty years ago 😄 8 1 Link to post Share on other sites More sharing options...

Carbon fibre is used to make lightweight dive tanks: We also use them for PCP air rifle re-charging. But.....! A steel dive tank has certificate and then a 5 year life (bit like a loco boiler) after which it cannot, and will not be refilled by a commercial company, until the tank has been inspected and re-certified for a further 5 years. A carbon fibre tank has no such regime. It has a date of manufacture and it is good for 10 years. There is no extension to that time limit, after which it has to be scrapped. One presumes that the industry safety standards for these tanks are worked out on an average charge/discharge cycle. Some tanks will go to scrap closer to the end of their safe life, whilst others will be well under, but still have get axed. Of course, these rules are only good if the user abides by them. If you have your own compressor, (capable of pumping in excess of 300 bar) then you can ignore the time limits if you feel brave (or stupid) enough. Had Titan exceeded what might be deemed a safe number of compressions/decompressions? I appreciate there are other factors, such as the acrylic viewing plate only being certified to a certain depth, but without any independent certification, it is hard to justify building what is in effect, a passenger carrying deep water submersible. From what I've read in the Media it's been suggested that very little appropriate testing was done to determine just how much pressure Titan was capable of reliably - and repeatably withstanding, along with how many dive cycles; I would've expected numerous prototypes to have undergone thorough tests to simulate such a lifecycle (including perhaps numerous real-life unmanned dives (with periodic NDT carried out if practical) until failure. Only then can a safe working life be determined. Of course, all this would depend on the manufacturing process being repeatable...... 4 hours ago, Tony_S said: My cousin’s husband told me about how they put components for motor vehicles (not anything exotic like mini subs) through testing. They had climate control test environments where they could simulate years of for instance desert daily temperature changes. They could also test for defects caused by extreme sunlight or cold. His last task before retirement was to manage the move to a new site. It had to be done so as not to interfere with any test in progress. The Great Empire had facilities for such testing - altitude, rain, salt spray, sand, temperature, sunlight etc. ISTR Aston Martin (or Jag?) used to rent the facilities; there was a similar setup in Bristol that was once used on a very hush-hush basis by a certain F1 Team - with only a handful of people aware and sworn to secrecy. And then on the first day a team of blokes in Red Overalls and all speaking Italian walked into the Restaurant at lunchtime.... 3 11 Link to post Share on other sites More sharing options...

After all if Dave Hunt and I built a full size Gotha bomber out of balsa and string, and started offering flights around Shropshire, I'm sure we could, but only if we first met the rather stringent insurance and aviation regulations. Failure to do so would get the operation shut down pdq, with crown court proceedings following in due course. Young Hippos might not be old enough to remember but the whole sad episode is reminiscent of the Comet disasters. We thought we understood the science but we didn't quite know enough of it. That caused many new procedures to be put in place but it sounds like many of them were not applied in this case. The hull was being subjected to a pressure change of almost three tons per square inch (5878 PSI). Not sure how many cycles of that pressure change carbon fiber could sustain. 2 3 2 Link to post Share on other sites More sharing options...

RMweb Premium PhilJ W Posted June 24, 2023 RMweb Premium Share Posted June 24, 2023 A lot of Boeing 747's are parked up out of use when older ones are still in service. The reason, the fuselages contain carbon fibre and after a certain number of pressurised flights (known as rotations) they can no longer carry passengers, only freight (but there is a glut of freight aircraft). Some are used as water bombers as they fly so low as not needing pressurisation. 9 Link to post Share on other sites More sharing options...
RMweb Premium PhilJ W Posted June 24, 2023 RMweb Premium Share Posted June 24, 2023 I have a pair of boots that I purchased over forty years ago. That was when I lived in Burnham-on-Crouch and in the winter of 1982 the town was snowed in for a week. Fortunately a boat chandler was open in the town and I was able to obtain a pair of sailing boots, half a size to big so that they could accommodate some thick woollen socks. I very soon found that I could walk on any icy surface while wearing them. I've still got them somewhere (and the woollen socks). 10 3 Link to post Share on other sites More sharing options...

Its just as likely that the majority of the meeja haven't cottoned onto that yet. Whatever it was, there must have been a brief frisson of panic aboard the submersible before the end, but no one on board would have registered the actual implosion.
