  1. Unfortunately it is too true. In particular from 1st October gas and electricity prices are rising by 80%. After they went up by 60% in April. And forecast for a further 80% in January. And god help us what happens in April. First rate video. Dunno who she is, but it calls the shots for sure.
  2. The unregulated power supply on the original T2 is its real Achille's heel. Other than thermal management that is. One thing to watch with T2 transformers is that the heater windings to the pentodes float at 500V. So there needs to be adequate insulation barriers inside the heater transformer to cope with that, and adequate insulation in the umbilicals. With mine I ran the floating heater wires inside the umbilicals inside a glass fiber sheath.
  3. It helps using it in one of these No slop at all.
  4. I have to check, but I think mine is 12". Yup. Freud 12", 36 tooth with negative hook, so at least it has no tendency to climb out of the cut. This is the beast https://www.freudtools.com/products/SD512 .
  5. Now you have to do what the Bullingdon Club do. This is a male-only "dining club" at Oxford University attended among other leading conservative politicians and Prime Ministers David Cameron and Boris Johnson. There are various initiation ceremonies of varying levels of distaste, including burning a £50 note (not alas as paltry as a fiver) in front of a homeless person on the street. Here's the infamous photo and what they are doing now. https://www.itv.com/news/2019-07-18/boris-and-the-bullingdon-club-where-are-they-now
  6. I've got one of those, shipped from the US by a friend. It was the only dado set that would fit my Wadkin radial arm saw. It is a frightening thing to use!
  7. There is good news from his website - he reckons to be back up and running later this year. He is in his mid 70s by the way. Clearly can't keep a good man down!
  8. One of the places I used to buy timber, run by a really nice guy, has burned to the ground. Apart from the workshop, which contained industrial grade Felder machines https://www.felder-group.com/en-gb/products/planer-thicknessers-planers-thicknessers-c1948 , his fine timber store went too; he used to supply musical instrument makers. The extract system burst into flames while he was working in there. He beat a hasty retreat and watched as it burnt to the ground. You can just about make out the carcase of the Felders and radial arm saw. Fortunately he was insured, and Just Giving raised £14k. https://mactimbers.com/
  9. There are some folks that you know would devour time (AKA a Chronophage) if you met them at a party. "This is really interesting - my 7th bandsaw was..."
  10. That is a good solution! But put an interlock on the door anyway. Costs nothing, and is a belt and braces precaution. My experience is with pulsed IR lasers, which of course you cannot see. Had to be careful to keep fingernails out of the beam, because that particular laser would blow a fingernail off. Frequency doubled into the green it used to attract flies and wasps, which would explode spectacularly. An interesting calculation was that a single pulse from that laser, if divided up evenly and without losses, was enough to cause eye damage to the population of London. It ran at 30 pulses per second.
  11. Anyone using laser engraving with a 20W laser needs to be exceptionally careful. That is 2000 times eye safe, and is a Class IV laser https://www.lasersafetyfacts.com/laserclasses.html . The raw beam will drill a hole in your retina, causing explosive boiling of whatever humor is next to the retina. Assuming that you aren't going to get the raw beam in your eye, scattered light from the focus is also far above eye safe. So - you absolutely need to wear safety goggles. Not Amazon hokey ones - but serious ones from say Thorlabs https://www.thorlabs.com/ , and expect to pay $200. Then interlock the door to prevent anyone in your household inadvertently walking in and getting eye damage. I spent many years working with lasers in this class, and wearing googles was mandatory as was interlocked doors. During laser safety training (also mandatory) an ex-Nam veteran said that nothing in active service remotely compared with the horror of looking at the world through his blood-filled eyeball. Nuff said.
  12. PIP Billy Woodman, founder of ATC loudspeakers. One of the audio greats. Too early at 76 after long ill health. https://atc.audio/
  13. He got his just deserts. She cut him out of her will. https://radaronline.com/p/nichelle-nichols-star-trek-startrek-last-will-testament-exclusive/
  14. RIP Isabella - what a nice doggy. She had a great life from the pics. But it sure is tough to say goodbye to an animal companion. The difficult kind thing to do. And RIP Nichelle Nichols. Alas boldly gone.
  15. Happy birthday Antonio! Hope you had a great (and hopefully cooler!) day.
  16. The main feature the foreground galaxy cluster, so massive (with visible and dark matter) that the light from more distant galaxies are gravitationally lensed into curved arcs. If you look deeply into the image you can find faint red dots - primordial galaxies that formed 600 million years after then big bang (so ~13.5 billion years ago) But you are looking at them as the were, 13 billion years ago But of course since then, they have receded further due to expansion of space. Somewhat paradoxically those far distant galaxies are now 32 billion light years distant, as a result of physics I used to remotely understand, but now rely on Wikipedia https://en.wikipedia.org/wiki/Expansion_of_the_universe#Measuring_distances_in_expanding_space
  17. My sincere condolences - how awful. As you rightly say, fuck dementia.
  18. Hope you have a great one Birgir! Happy birthday!!
