Titan Submarine

 A few weeks ago I was discussing the loss of the OceanGate Titan tourist submarine with my brothers, one of whom is a skilled mechanical engineer. Apparently everybody expected it to collapse because a cylinder with domed ends on it is a really bad shape to put under pressure. I still find it rather had to believe, but as a species we only know how much pressure you can put on a cylinder if it's perfect. As soon as it goes slightly out of round it's much much weaker, but we can't really calculate how weak.

To demonstrate this effect to me they devised this beautiful practical demonstration. The beer can can hold my weight while it's intact. They then introduced the tiniest imperfection (by prodding it gently with a cotton bud) and it collapses catastrophically.

My least favourite thing about the loss of the Titan - apart from the loss of life - is the system of acoustic sensors and strain gauges supposed to keep it safe. Everybody was a naysayer and didn't believe they would work. They naysayers were kind-of right, in that the submarine collapsed and killed everybody inside, however, they did pick up a loud click (probably a delamination) on dive 80, and the strain gauges did show that the performance of the hull was degraded after the click. If only they'd known how to analyse the data.

Dear Sir. I recently attended your Norfolk Residential Teambuilding Experience. I very much enjoyed it, I would like you to extend my thanks to everyone involved, and I believe it represents excellent value for money.

HOWEVER

There are some points which I feel fell below what could have been expected from the experience:

Free Parking: While my allocated space was close to the cottage, it was accessed along a lane which was clearly marked as "Road Closed" and then up a steep and narrow driveway made of slippery wet gravel. I also feel that my car was not as safe as it could have been as the organisers were moving several other vehicles around in the same car park.[18]

Circuit Driving Experience: I enjoyed the day, but I thought that the preponderance of vehicle maintenance tasks and safety checks detracted from the driving experience. I was also unimpressed with the organisation of crash helmets and intercoms. One of my fellow attendees had a crash helmet with an intercom, I had a crash helmet and an intercom but the two were incompatible and I had to remove my intercom because my helmet wasn't suitable for the other attendee. Then there was a third intercom system for the instructors which was incompatible with the first two.

English Pub Games: The rules seemed to be poorly explained, and while I bonded with my partner during the doubles pool, the session seemed more competitive and divisive than team-building

Forestry Management and Firewood Production Lesson: I don't think that the brochure made clear how tiring this lesson would be, or gave any minimum standards for the physical fitness of the participants[19]. There was no water available at the site, and I feel that the PPE provided was wholly inadequate[20].

Off-Road Driving Experience: I think that the instructor assumed too much knowledge of the vehicle involved on the part of the guests.[21]

Breakfast: The continental breakfasts really consisted of toast and a selection of jams and preserves. This seems bizarre when you discover that they are served in the same well appointed kitchen that is used for the cookery lessons.

And this gets to the crux of my complaint. While the individual activities were generally excellent, taken as a whole the course is incoherent and disjointed. We did the vehicle maintenance challenge a day AFTER we did the circuit driving experience, yet there was a heavy emphasis on vehicle maintenance during what should have been a driving experience. On day 3 we had a breakfast of toast, literally minutes before we started cooking hot food. We used sharp knives during the cookery tuition, but were then shown how to sharpen them AFTER having used them. Surely you can see that there would have been a narrative through line to the day if we'd gathered the wood and sharpened the knives BEFORE we started using them for cooking, and that the tasting should have come straight after the cookery tuition.

There was very poor coordination between the attendees which seems weird for a team building event. I felt that I started to develop a bond with my fellow attendee at the circuit driving experience, but his itinerary precluded him from attending the evening meal at historic Norfolk inn and the ale tasting. He was staying in a separate cottage and we met him again for English pub games, but he seemed not to even have been invited on the nature reserve walk even though I understand it was very close to his accommodation.

Best Wishes,

1. I went and stayed with my brother for a few days
2. I absolutely took the piss using all his hot water to take long hot deep baths
3. and tried to drink his fridge and his wine-rack dry
4. we went to Snetterton to shakedown and test my sports car's newly rebuilt engine
5. we had to try a couple of beers at the pub before we found one in good condition
6. toast
7. I've been shown how to use his bean-to-cup coffee machine
8. we tidied up the family plot at the cemetery
9. between us we pretty much sorted out the tracking on his worn out Toyota Hilux.
10. games of pool at the pub
11. toasted sandwiches made in a genuine 1970 Breville sandwich toaster
12. I helped him cook a really good curry and stew
13. I wanted to piss about with a wetstone and a strop on one of his knives
14. coffee, fags, and chatting
15. I helped him clear the lane into his woods
16. and I had to drive the Hilux up it
17. we ate the curry
18. my sister in law forgot my car was there and nearly reversed in to it
19. I wasn't up to the job. I got tired and dehydrated, then drank a couple of pints of beer, and then nearly fainted when I got out of a bath.
20. I got thorns through my gloves, thorns through my trousers, thorns in my bootlaces and nettles up my arms.
21. I didn't understand the transfer box on the Hilux

Horse Karen

 They say it's the 95% of lawyers that give the rest a bad name. Something similar happens for motorcyclists. Those with loud exhausts, dazzling headlights and poor road manners give the rest of us a bad reputation. This week I saw something similar with horseriders.

Horses can be quite temperamental and easily startled, and they're not excellent in traffic, so those of us with motor vehicles are taught to pass them wide and slow. Last week I was on Dartmoor in my sports car. I was on a winding road with a 30 m.p.h speed limit and I was already going slower than that when I saw a horse coming the other way. My exhaust is loud so I switched off the engine and put the car in neutral to coast past it. My brakes and tyres can be squeaky so I decelerated gradually and coasted quietly past the horse at around, I would guess, 10 m.p,h.

The rider, rather than waving her thanks to me, was red faced, gesticulating wildly, and shouting at me to SLOW! DOWN!

Side Quest

 Last week I met one of my team for the first time, he'd come to Plymouth from Lancashire for a company celebration. What's odd is that I, one of my colleagues, and his girlfriend are all NPC's. His girlfriend asked him to bring back a memento of the Westcountry - ideally a plush seagull. His colleague knew exactly where you could buy one - the Students' Union shop, and I was able to walk with him to the S.U. shop.

This is a straightforward fetch-quest from an unimaginative video game. His girlfriend is the quest giver, his colleague is a helper character, and I'm either another helper or the map.

Dyno

 My Caterham has been to the dyno and it's good news all around. The replacement lambda sensor is working correctly, and it's fuelling correctly.

Everybody is very pleased with the engine rebuild, and it's making more power than the advertised power when it was new.

In the top graph the blue line is power, the red line is torque. the bottom graph is air:fuel ratio. What's interesting is that it's enriched at low revs. This is probably to make it easier to drive in traffic, but it might be a childish ploy to make it pop and burble on the overrun so it sounds like a racing car. Or something to do with the way they're tuned the variable valve timing.

They think the most important bits of the process were skimming the head for slightly increased compression, 3 angle valve seats, and careful valve grinding.

Caterham Lambda Sensor

 I have a Caterham Seven with the 1.6l "Sigma" engine.

The original lambda sensor was Ford 1351337 These are now unobtainable or fiendishly expensive. I have replaced it with Ford 1327547. The sensor and the plug are identical, it's just that the cable is a bit shorter.

I can now say with confidence that the new sensor is functionally identical too, because my car has just come back from the dyno and it's fuelling correctly.
