  1. Chyba że chcesz pisać w języku takim jak Polski.
  2. This PM we are entertained by a local Caelie (?) Group
  3. Forgot to answer. There are several versions. The one that was floated (!!!) On the canal at Salford Quays was 10metres across. This one is seven meters.
  4. Casserole a great success - the secret is in dusting the pieces of meat in wholemeal flour before browning. And thank you for the link! I thought that such knobs would be unobtanium, unless you wanted thousands of them! John
  5. Yesterday evening, we had the 'thank you' drinks for volunteers like me at the Lancaster Priory "Festival of the Earth". This was centered on the Luke Jerram artwork 'Gaia', which has been in the nave of the Priory for the last four weeks: As you can't see, it rotates every four minutes, and is suspended from above, s you can walk all around it, and underneath. The Priory built a whole series of events around Gaia, concerts and displays, including a colouring competition for kids, that I expect other venues will do as well. There are several versions of this work that are touring the world: https://www.lukejerram.com/ Do try to go and see it - most impressive! But into each life some rain must fall, and while I was out I had left a chicken casserole in the oven on a low light. The casserole dish had no lid, so I took one from a frying pan to cover it. And when I got home this is what the lid looked like: They don't make frying pan lids like they used to! Or at least not to be baked in the oven! So I need to make a new knob. I could turn one on my wonky lathe, but what material to use? If I keep it out of the oven in future, it's not going to get that hot, so will aluminium burn my fingers? If I cut slots in the metal, increasing the surface area, would it 'run' cooler? Wood would better insulate the hand, but the dishwasher would soon disintegrate softwood and I have no hard wood stock. I have some Tufnol - anyone used that for kitchenware handles? John
  6. Colin, Fascinating, if revolting, list of the various ticks that plague us (excepting Tories) here: https://www.esccapuk.org.uk/page/Ticks/36/ Could that help you ID your parasite? John
  7. Rydere, Reading back in the post, you said, "Prior to instatting Megajolt into fuel injected Fiat I ran the system on a test stand engine that was carb'ed with Weber IDF 40's, all ran well" I'm confused! Do you mean that the engine HAD been injected, but you tested it with carbs? As said, MegaSquirt needs a crank position sensor, usually provided by a toothed wheel that lacks one tooth. Then absolute timing is done in software. John
  8. Rydere, Are you confusing Megajolt, an ignition system that uses the Ford EDIS system to provide, er, ignition, with MegaSquirt, an allied fuel injection system? MegaSquirt also uses a trigger wheel to time the injections. John
  9. A live axle, solid, on cart springs or trailings, would need one flexible from chassis to axle. So three hoses - two front, one rear. But yes, any car with IRS needs four! So Hel have the wrong info. JOhn
  10. The online info about Megajolt is FULL of how to set up the toothed wheel on the crankshaft. Read that first? JOhn
  11. How about a satellite phone? Amazon seem to sell gadgets that allow you to text and email via Iridium: https://www.amazon.co.uk/ZOLEO-ZL1000-Satellite-Communicator/dp/B07X59RH7T/ref=asc_df_B07X59RH7T/?tag=googshopuk-21&linkCode=df0&hvadid=598165945323&hvpos=&hvnetw=g&hvrand=13080930904545822721&hvpone=&hvptwo=&hvqmt=&hvdev=m&hvdvcmdl=&hvlocint=&hvlocphy=1006854&hvtargid=pla-918768790043&psc=1# £200 or so, but maybe cheaper than other means? Or, a 'satsleeve' that looks as if it gives you full connectivity by satellite, at twice the cost. Near me, "B4RN', Broadband for Rural Networks, has been a successful way to bring fast bb to farms and villages by cable. But that is more of a community project: https://b4rn.org.uk/community/volunteers/ John
  12. All, As I told in another post, I bought TWO of these riveters, but only need one! What am I bid for this? It is used, but isn't worn or 'floppy' and works well. I've tried it! Three 'nozzles' for different sized rivets, it will take 5mm which I've also tried. To simplify the deal, I'd be glad to let it go for a significant charity contribution, your choice, or HelpforHeroes, to include postage, which might be about £8 as it's just over the PO's 2Kg limit. PM me please! John
  13. Nick!? Stroke? You, loved one? Sorry to hear either way. If I may defend the NHS, to which Our Majesty has just awarded the George Cross, the Victoria Cross equivalent for civilian heroism, in recognition of its pandemic efforts? "The NHS has done so much with so little that it can now do anything with nothing" was always a cynical remark and the situation today proves that. After years of cumulative bed reduction in hospitals -since 1990 the number of hospital beds has more than HALVED (NHS hospital bed numbers | The King's Fund (kingsfund.org.uk)) - while the number of 'social care' beds has stagnated, the inevitable effect being 'bed blocking', the unkind term for people who are fit to leave hospital, but too old or ill to look after themselves and for whom there is no provision outside. We now have fewer hospital beds per 1000 citizens than any other European country, EG UK - 2.5, Germany 7.9, Spain 3. This is because while 'modern medicine' can cut down the time that it takes to make someone dischargeable, the rationale for the bed reduction, there was no corresponding investment in accommodation for the people who now 'bed block'. BEFORE the pandemic, every month, there were 148,000 "delayed days" - days in which a bed was blocked as above. This situation has been well known for twenty years, with only warm words and clapping from the politicians. This means that while people still come to A&E and some need admission, there are no beds in the hospital for them to go to. They stay in A&E, while the queue outside forms, and of course the paramedics cannot leave their patients on the doorstep, so the ambulances are part of the queue. ALL the Ambulance Trusts in England are now on the highest level of alert, which is normally used only in a civil emergency, a disaster that will occupy the majority of staff and vehicles for some time. But even a Major Accident will be dealt with in hours and the Service stood down to normal - this shows no sign of abating, and cannot, until something is done to free up hospital beds. We may know the saying "Lions led by Donkeys" of the military management of WW1. We now have recognised Heroes, the staff of the NHS, George Cross, led by politicians who have no vison and no humanity. The most valuable social instrument of all time, a National Health Service, the first and the greatest in the world, laid low by governments more interested in obsessive self and national aggrandisement. I'm sorry but if anything could get me to the barricades it's this. I'm sorry too for your personal situation, Nick. I'm sure you will direct your justified anger where it is deserved! John
  14. My cycling, is not as venturesome, but useful when parking would otherwise be difficult, and fun as well. My old bike was stolen a month or so ago, and is either in parts or at the bottom of the canal by now, so I looked for another on Ebay. What I got was what I thought was a bargain - so much so that I wonder if it was knicked from someone else! Easily worth £600 new, it is nearly new and I got it for tenth of that. More, I collected it from an address and a seller that I would not associate with sport cycling! BUT, it had a problem - with eighteen gears, three chain and six on the wheel, it wouldn't select them properly and sometimes the chain would fall between the chain gears and jam up completely! I fiddled with the selector adjustors, lubricated them and made no improvement, so knew It needed proper expertise and took it to the local bike shop for a 'tune-up'. It was better when I collected it, but on cycling home there is a slope, I changed down to the lowest gear and - WHAM! The chain seized up completely! The pedals were unturnable! Walked it back to the shop and the most apologetic bike technician found that the bolts holding the chain wheels in place were all loose!! They were so out of line that the chain had jammed. He had never seen this before but "should" have spotted it, he said, and of course dealt with it FoC (6 Newton Metres per bolt, if you're interested!) And the problems are solved! Happy cycling! John
  15. Reflecting on Le Mans, it's amazing how transferrable are some experiences. I posted above a pic of the valve gear of the 1931 Talbot - significantly different to the otherwise very similar 1950s Triumph engine and somewhat more complex. I took the pic while assisting the chief technician as he changed a head gasket and was reassembling the valve gear and re-setting the tappets. He had all his tools on a tray on the scuttle and was reaching for them as required. I went to help by handing them to him as needed, and suddenly realised that I had seen this situation before - in the operating theatre! A theatre sister does this, has the next tool - instrument! - that the surgeon needs ready, so that the cutter doesn't need to say what they want next, it's just put into their outstretched hand, blunt end first, of course. So, copying the many theatre sisters I've seen before, I tidied the tool tray, had the two spanners and feeler for tappet adjustment ready and handed my boss the valve components in order. It was a credit to him and to the value of the procedure, that he immediately took on this different plan, worked with it and thanked me afterwards. Even weirder was later, I was chatting to our senior driver and he asked me if I was medical! He had recognised the "theatre technique" I had used, not from his own experience but from film and TV! John
  16. Wow! Is that the new pic from the JWSS? This is a spectacular success,especially after the near debacle (only saved by the fact of US astronauts ability to 'space walk') of Hubble. The Hubble cannot 'see' as far back on time (= as far away) as the Webb, and those multiple gravitationally lensed galaxies, all very red, indicate something absolutely massive somewhere below that local star with the light bars, and very, very far away!
  17. Both, Iain ! Temperature sensors are notoriously poor quality these days. I always calibrate mine, by suspending a new one in a water bath on my camp stove and heating it from room to boiling water temp. Not as hot as it will get in use, but gives you the slope of the response. You may measure the resistance of the sensor with a multimeter, or else just observe the reading on the temp gauge. This is the sort of thing you will see: the purple line is what it should do. but sad to say, even a new sensor may not do so. But 70C if true is too cool for normal running. You pressurised system should allow the coolant to run at about 112C. John
  18. Watch highlights on C4. The Dutch are so fond of flares that the grandstand they have monopolised looks like a forest fire during the formation lap! John
  19. Ooops! NOT "jet engines"! (which run at 1700C+!)
  20. Ian, you quoted running temps are anomalous. Engines run with coolant at MORE than 100C for efficiency (the higher the temp the greater the efficiency, but these are jet engines and a compromise must be made!). This is why the coolant system is pressurised and the rad cap has a spring loaded valve. I'd suggest you have air in the system that needs purging. John
  21. Well done! Stayed neither by snow nor rain nor heat nor darkness - nor depth of sea nor height of air - will delay this messenger from accomplishing their appointed course with all speed! (Herodotus 520 BC)
  22. No! No! Not .. .. the Shrubbery!! That would be worse than the Ni!
  23. Fortunately for the UK, and unlike another Great Nation, a repeat of the Bellingham case is unlikely here, and we don't put failed political leaders on trial, like the other, Previously Great But Now Shamed Before The World nation. The best we can hope for is to be confined in a Shepherd's Hut while they write their unsellable memoirs. John
  24. Cromwell? We might need another John Bellingham!
  25. Roger, Forgive me advising an old hand! Do you have an Oil temp gauge, and does it run hotter than it should on your epics trips? Should be less than about 125C (260F). John
