  1. I used to get 'remould quality' tyres. They were always new tyres, but were often in sizes that had been overstocked, or ones with perhaps a tread pattern defect from the mould.
  2. The blade profile is optimised to do most jobs, most likely none of them particularly well. The offset from the centre line will have to be significant, if the friction to rotate the blade is high. So, if you reduce thart distance, I would guess you will need to take very light passes to reduce the friction caused by pressure, but not so light that there is not enough pressure to turn the blade. If you make the rear edge more vertical (the point more acute) then the tip of the blade will be weakened, and will most likely not stay sharp for long. I guess you will need more than one blade to successfully experiment, but seeing as it is not doing what you want at the moment, then you may as well have a go. The photo is of three spare blades for a hand held swivel (drag) knife. the rule calibrations is in mm. They simply fit loosely in a hand piece, plenty of slack, but the blade is actually 'leaning back, and is quite acute, Because it is most likely stabbed into the sheet when starting the cut, and being controlled by hand, more sensitivity can be applied compared to being machine driven. The blades and knife handle were bought from 'the Range' a few years ago, for not much money, but it may be possible to adapt your blade holder to take them. e.g. pull out your steel blade, and drill plastic to take these blades
  3. During a visit to my doctor, I asked him, "How do you determine whether or not an older person should be put in an old age home?" "Well," he said, "We fill up a bathtub, then we offer a teaspoon, a teacup and a bucket to the person, to empty the bathtub." "Oh, I understand," I said. "A normal person would use the bucket, because it is bigger than the spoon or the teacup." "No," he said. "A normal person would pull the plug. Do you want a bed near the window?" DO YOU WANT THE BED NEXT TO MINE?
  4. The Story of the Haircut With barber shops and hair salons closed in most states this story is very timely. We all need to pitch in and help one another during times of stress, difficulty or danger. Enjoy this story. There are lessons to be learned from it. The Story of the Haircut Blessed are those that can give without remembering and take without forgetting. One day a florist went to a barber for a haircut. After the cut, he asked about his bill, and the barber replied, 'I cannot accept money from you, I'm doing community service this week.’ The florist was pleased and left the shop. When the barber went to open his shop the next morning, there was a 'thank you' card and a dozen roses waiting for him at his door. Later, a cop comes in for a haircut, and when he tries to pay his bill, the barber again replied, 'I cannot accept money from you, I'm doing community service this week.’ The cop was happy and left the shop. The next morning when the barber went to open up, there was a 'thank you' card and a dozen donuts waiting for him at his door. Then a Congressman came in for a haircut, and when he went to pay his bill, the barber again replied, 'I cannot accept money from you. I'm doing community service this week.’ The Congressman was very happy and left the shop. The next morning, when the barber went to open up, there were a dozen Congressmen lined up waiting for a free haircut. And that, my friends, illustrates the fundamental difference between the citizens of our country and the politicians who run it. As Ronald Reagan said: "Both politicians and diapers need to be changed often and for the same reason.”

    If you're a coop member (maybe if you're not) you can phone their ho, and they'll credit you the amount outstanding, and maybe a bit more.
  6. You can spend a few minutes thinking up words, and go to https://www.thisworddoesnotexist.com/
  7. I get them from Paypal, except they are not from Paypal...
  8. This reminds me of something I saw in Engineering magazine, a number of years ago. Iirc it was an electric loco in India, stopped on a slight gradient, without brakes applied for a fair amount of time. The driving wheels slowly rotating in the same spot, melted half way through the track.
  9. Old people can often just do what they want - they don't have so much to lose.
  10. Ajoke from another time, or another place... So, I was in the McDonald’s drive-through this morning and the lady behind me honked at me and flipped me off because I was taking too long to order. Wow. “Take the high road” I thought to myself. So I paid for her food. I moved up and she leaned out the window looking all crazy at me because the cashier told her I paid for her food. She felt embarrassed. When I got to the second window to get my food, I showed them both receipts and took her food too! I paid for it, it was mine! Now she has to wait even longer. She’s gonna learn today you just don't mess with us old people.
  11. fwiw, the router is most likely fine, but you'd get a better finish in ply with a decent down cutting bit. It may be a bit late for you, if you've done all the slots, but Here is a link to the sort of bits I refer to - https://www.shop-apt.co.uk/2-flute-down-cut-carbide-routers-for-wood-mdf.html A simple ply/hardboard jig can be made to limit the travel of the router since you'll need to make more passes to get the required width of slot, provided the 6mm shank will fit the B&D collet.
  12. nought wrong with Lenovos - old or young...
  13. Hi Ian, very nice experimentation you're doing there. I do not have any of these machines, but a few comments may be useful. The plastic sheet is sort of sticky. It is the type of problems that folk get when first machining aluminium without using any lubrication. When cutting plastic with a knife blade, the displaced material will need to go somewhere, generally forming a raised lip ( a burr) at the edge of the cut. However, on these machines, the depth setting is governed by the depth stop rubbing on the surface of the material, which will cause more friction, and obviously the stepper motors are cogging -missing steps- and as you say you may as well give up when that happens. Taking a number of lighter cuts may overcome that. Using a more brittle material may also solve that problem. The machines are flexing too much for heavy cuts, but I expect they are ideal for cutting paper and some fabrics, It may not help, and you may not want to try it, but perhaps first giving the plastic a light spray of a lubricant (WD40?) may reduce the friction, or try different plastic sheets. The software, looks to be very buggy too. for cutting any shape with lines at right-angles, you only need two' walkabouts', if the cutting blade can be retracted. Of course, more walkabouts may increase the speed of cutting the job, since it will not be taking time cutting air to return to cut the next parallel line. Do you know the final code that the machine uses, hpgl, g-code, whatever, or do you not have access to that? Best wishes, Ray
  14. This is far more European in nature.
  15. That T-shirt statement would be seen as a challenge in many parts of the UK.
  16. AN ATHEIST IN THE WOODS An atheist was walking through the woods. 'What majestic trees!' 'What powerful rivers!' 'What beautiful animals!' He said to himself. As he was walking alongside the river, he heard a rustling in the bushes behind him. He turned to look. He saw a 7-foot grizzly bear charge towards him. He ran as fast as he could up the path. He looked over his shoulder & saw that the bear was closing in on him. He looked over his shoulder again, & the bear was even closer. He tripped & fell on the ground. He rolled over to pick himself up but saw that the bear was right on top of him, reaching for him with his left paw & raising his right paw to strike him. At that instant moment, the Atheist cried out: 'Oh my God!' Time stopped. The bear froze. The forest was silent. As a bright light shone upon the man, a voice came out of the sky. 'You deny my existence for all these years, teach others I don't exist and even credit creation to cosmic accident.' 'Do you expect me to help you out of this predicament?' 'Am I to count you as a believer?' The atheist looked directly into the light, and said: 'It would be hypocritical of me to suddenly ask you to treat me as a Christian now, but perhaps you could make the BEAR a Christian?' 'Very well', said the voice. The light went out. The sounds of the forest resumed. And the bear dropped his right paw, brought both paws together, bowed his head & spoke: 'Lord bless this food, which I am about to receive from Thy bounty through Jesus Christ our Lord, Amen.'

  18. The above charts are most likely based on best guess results, and doctored to present the view that the publisher wants. If you are looking for a trend, you do not take a high resolution chart, it will be full of 'ripple'. If you look at daily results, being pedantic, is the day from midnight, dawn, 9am, whatever, for all sites? Still, playing around with numbers and charts can be interesting, particularly when trying to correlate results.

    Now its there, nobody will want it.
  20. Pork sausages are made of bits of pork, beef sausages are made from bits of beef. What are vegetarian sausages made from? Linda McCartney's consist of Rehydrated Textured SOYA Protein (70%), Water, Rapeseed Oil, SOYA Protein Concentrate, Seasoning (SULPHITES) (Dextrose, Salt, Flavouring, Onion Powder, Yeast Extract, Colour: Red Iron Oxide), Fortified WHEAT Flour (WHEAT Flour, Calcium Carbonate, Iron, Niacin, Thiamin), Stabiliser: Methyl Cellulose, Tomato Purée, Salt, Raising Agent: Ammonium Carbonates No mention of any vegetarians - shame. I hope they get the balance right - Methylcellulose is a bulk-forming laxative that increases the amount of water in your stools to help make them softer and easier to pass. Methylcellulose is used to treat constipation and to help maintain regular bowel movements. Breathing ammonium bicarbonate can irritate the nose, throat and lungs causing coughing, wheezing and/or shortness of breath. Repeated exposure may cause bronchitis to develop with cough, and/or shortness of breath. Health effects can occur some time after exposure to ammonium bicarbonate and can last for months or years. Sulphites can cause itchy skin, low blood pressure, abdominal pain, and diarrhea—as well as life-threatening anaphylactic shock and asthma attacks. However, you have to be sensitive to sulphites to see these reactions. About 1 percent of people have a sulphite sensitivity. Maybe a bit of pork, oats and sawdust is healthier. (not sure about the plastic 'skins').
  21. Skimmed milk is a subset of milk, if you like. They are stating that there is nothing added or taken away from that subset. - the adding/taking away refers to the 'skimmed milk', not the original whole milk, unless it refers to the whole milk elsewhere, However, if in fact it was skimmed milk posing as whole milk, then I could see a lie being.perpetrated. There are plenty of similar examples, but I can't think of any off hand, but I'm sure you could. I expect, you cam get skimmed milk with added vitamins/flavourings/whatever, when the adding/taking out statement would not apply. In the UK, we have whole milk, channel island milk, semi skimmed and skimmed milk, broadly defined by fat content. Often the milk is blended, to get the correct fat content- e.g. higher fat content milk from Guernsey or Jersey cows added to the lower fat content milk from more volume producing animals. Here is a link which explains how milk is produced. https://www.ciwf.org.uk/farm-animals/cows/dairy-cows/
  22. I thought that is what marketing is all about. - wording that looks as if it is important, but in fact is usually completely meaningless.
  23. I don't see what the problem is. The item is skimmed milk. They are saying they have neither added to are taken anything away from that item. If it was sliced bread, would you think they would have pinched a few slices? (Asda may be different)
