yet more of his rot: I will, FLUSH the usual senile rot Hard to tell who is feeding who. The senile Ozzie the Scottish troll? Or the gay Scottish ****** the senile Ozzie? LOL -- Richard addressing Rot Speed: "**** you're thick/pathetic excuse for a troll." MID: |

A leg of lamb with a nice crisp brown fat layer on the outside and nice pink meat on the inside is vastly superior to the same leg of lamb the same all the way thru. Same with a rare or medium rare steak. True of meat pies too, you want a crisp crust with cooked meat inside, not the soggy crust you get with a microwave. Same with toast, its real toast because it isnt cooked uniformly, its toast because its more cooked on the outside than inside. The only advantage I can see for flatbeds is, as Panasonic advertise, you can stick any shape of dish in there. It doesn't need room to rotate. And presumably is harder to design so it works well. Spinning aerial and a wave guide tube, not that hard surely? But that doesn't get the same uniform effect as rotating the food. |

But that doesn't work very well for those who only have a car with the bigger stuff like mattresses, lounges, dead fridges etc. Our council is unusual in that regard tho, most councils here do have a few days a year where they will show up with a truck and pick up the big stuff that's left on the nature strip.

So how do they make them flat under the food cavity in flatbed ovens? Does the magnetron sit under there and is redesigned to be flat? Or is there some kind of fancy rotating waveguide, and the magnetron sits at the side as before? Basically the later I should think. The one I had in the 1980s had a large aperture covered with mica on the roof of the cooking cavity. The Magnetron was at the side of the cavity with a brass wave guide leading up to the top. A squirrel-cage fan blows air up the wave guide and not only cools the Magnetron, but also rotates a paddle-wheel at the top, a rotating antenna, carrying multiple reflectors thar distribute the radiation throughout the cavity. I imagine modern bottom entry ones do a similar trick, but I have yet to work on one. I didn't realise they were available in 1980. So why aren't they all like that? Does it add a lot to the price? The one we had is in the last illustration on this page https://www.photomemorabilia.co.uk/P...iterature.html I've still got the 170 page hard-back cookery book. That looks quite a sophisticated one for the early 80s. We bought one around 1981 and it had just a simple turn and 'run back' timer. It did last about 17 years, with only a couple of O rings in the turn table drive. We only disposed of it as it started to look tatty. I'm still using the Sharp I bought in 73 almost every day. It does have a proper electronic control and display. Never had to do a thing to it. Corse now it will curl up and die and it will be your fault. Whatever happened to Sharp, Nothing special here. they still seem to be in business, Yep. but I haven't seen anything made by them for a decade or two. They arent as cheap as the worst crap but still buyable here. https://www.sharp.net.au/ Maybe here too, but I just haven't seen anyone with a Sharp device for 20 years. They used to be everywhere. AFAIK they were always midrange. Not overpriced like Sony, but decent. Something like LG. Just checked a retailer he https://www.currys.co.uk/gbuk/househ...-criteria.html 5 Sharp microwaves on offer, but 40 Russell Hobbs, 29 Bosch, 24 Swan, 15 Samsung, 25 Hotpoint. So not the most popular by far. There's heaps here https://www.sharp.net.au/home-products/microwaves |

There are also a few "small electricals" bins around that take items up to the size of a VCR. Some councils will collect small electricals left out on the kerbside with the domestic waste. AKA Gypsies. |

I imagine modern bottom entry ones do a similar trick, but I have yet to work on one. I didn't realise they were available in 1980. So why aren't they all like that? Does it add a lot to the price? The one we had is in the last illustration on this page https://www.photomemorabilia.co.uk/P...iterature.html I've still got the 170 page hard-back cookery book. That looks quite a sophisticated one for the early 80s. We bought one around 1981 and it had just a simple turn and 'run back' timer. It did last about 17 years, with only a couple of O rings in the turn table drive. We only disposed of it as it started to look tatty. I'm still using the Sharp I bought in 73 almost every day. It does have a proper electronic control and display. Never had to do a thing to it. Corse now it will curl up and die and it will be your fault. Whatever happened to Sharp, Nothing special here. they still seem to be in business, Yep. but I haven't seen anything made by them for a decade or two. They arent as cheap as the worst crap but still buyable here. https://www.sharp.net.au/ Maybe here too, but I just haven't seen anyone with a Sharp device for 20 years. They used to be everywhere. AFAIK they were always midrange. Not overpriced like Sony, but decent. Something like LG. Just checked a retailer he https://www.currys.co.uk/gbuk/househ...-criteria.html 5 Sharp microwaves on offer, but 40 Russell Hobbs, 29 Bosch, 24 Swan, 15 Samsung, 25 Hotpoint. So not the most popular by far. There's heaps here https://www.sharp.net.au/home-products/microwaves Yes, but how common are they compared to other makes? -- If you can't beat your computer at chess, try kick boxing. |

I think the mistake is that the cavity is not moved in relation to the food so standing waves still exist in the same places and only moving the food relative to those is a true answer to this. End of story. Brian That doesn't make sense. Spinning the pattern of microwave radiation must be identical to spinning the food. In both cases they are rotated in relation to one another. not identical at all. turntables produce much better evenness than stirrers. Both together are best. As I said, it's relative. The food and the microwave pattern are relative to each other. Where the oven is and where the kitchen is don't matter. If you rotate the food, or rotate the microwave pattern, PRECISELY the same effect is achieved. I know you think that, you already said. And as so many have pointed out you're clueless. Not one person has pointed out why one is more efficient than the other. I will, particularly with the microwaves with a built in meat temperature sensor. Clearly a lot easier to do those with the food not rotating. And I can also see why rotating the food gets a more even distribution of the microwaves into the food too. Harder to explain that one tho. I see no way it could be explained. Two objects, the food and the microwave pattern. Rotate one, rotate the other, same effect. But you can't rotate the microwave source like you can the food. Rotating some metal thing at the end of the waveguide the microwaves are coming out of is nowhere as effective as rotating the food as far as getting an even distribution of the microwaves in the food is concerned. Why not? Basically because of the frequency used, you get standing waves in the oven and some rotating metal at the end of the waveguide doesn't have all that much effect on those; I see. But Panasonic seem to think it works. Anyone ever compared the two as in how evenly the food gets cooked? When they metal thing had rotated 90 degrees, so has the weave pattern. No, because you get standing waves in the part of the microwave where the food is. Yeah I was (incorrectly) thinking those would change shape with the source moving, but I guess not. Precisely the same effect as if the food had rotated 90 degrees. No, a quite different effect as the food moves thru the standing waves. Please do explain and I will be happy to accept I'm wrong. I doubt Panasonic will though. With anything where you see both offered, there must be good reasons for both approaches and it can't just be habit/tradition when its been going on for 40 years or more now. Price I would think. Maybe. I've never had a good look at how the flatbed microwaves do it. Most likely just put their dead ones in their wheely bin and we don't allow people to put them on the footpath for the council bulk collection in my council anymore, so I have never had the chance to have a look at a dead one.

Ours doesn't refused to take it, you're free to take it to the dump yourself, and pay $25 per tailer or ute load, $10 per car or station wagon and they have 2 or 3 free dump weekends a year as well. You have to pay to dump it?! But you pay council tax to cover that. Plus they're getting the raw materials! They're conning you threefold! But that doesn't work very well for those who only have a car with the bigger stuff like mattresses, lounges, dead fridges etc. Find someone with a trailer, they allow those here. They (for some reason) charge commercial dumpers, like gardeners, tradesmen etc, but sensible tradesmen take the stuff in a trailer attached to their own car then don't pay :-) Or if you go in the last half hour before closing time, there's nobody at the entrance to charge you and you just drive straight in. Our council is unusual in that regard tho, most councils here do have a few days a year where they will show up with a truck and pick up the big stuff that's left on the nature strip. Not collecting stuff free is a silly idea - the poorer parts around here where people don't have cars, their TVs just get dumped on the nearest bit of land until the council comes to collect them. Mine refused to collect an old portable TV for recycling, Our dump has a 40' container you put that stuff in that is replaced when its full. Why should I drive all the way to the skip just for a 14" TV? It went in the normal waste wheelybin, **** them. so I put it in the landfill bin and hid it under some normal waste. Would have been funny if the tube blew when it was tipped into the lorry. Our trucks that show up every week compress the rubbish and that would normally explode the tube. Ours compress too, but I don't think they're strong enough to implode a tube.

Most large supermarket car parks have bins for bottles, paper and card &c., though usually this is also collected with the domestic waste in separate bins/boxes. Ours now have machines that pay you for bottles with barcodes on them. Corse you pay more for the bottles with stuff in them when you buy them too. They're thinking about doing that insanely stupid idea here. I already recycle my bottles in one of my wheelybins, why should I go to more trouble? The rationale is that when each has a cash value, in our case 10c each, you are less likely to just toss them out the car window or leave them behind after a picnic etc and that if you do that, some kid will likely collect them to get the cash for them. Ours hasn't been going long enough to say yet. And its bottles and cans. |

End of story. Brian That doesn't make sense. Spinning the pattern of microwave radiation must be identical to spinning the food. In both cases they are rotated in relation to one another. not identical at all. turntables produce much better evenness than stirrers. Both together are best. As I said, it's relative. The food and the microwave pattern are relative to each other. Where the oven is and where the kitchen is don't matter. If you rotate the food, or rotate the microwave pattern, PRECISELY the same effect is achieved. I know you think that, you already said. And as so many have pointed out you're clueless. Not one person has pointed out why one is more efficient than the other. I will, particularly with the microwaves with a built in meat temperature sensor. Clearly a lot easier to do those with the food not rotating. And I can also see why rotating the food gets a more even distribution of the microwaves into the food too. Harder to explain that one tho. I see no way it could be explained. Two objects, the food and the microwave pattern. Rotate one, rotate the other, same effect. But you can't rotate the microwave source like you can the food. Rotating some metal thing at the end of the waveguide the microwaves are coming out of is nowhere as effective as rotating the food as far as getting an even distribution of the microwaves in the food is concerned. Why not? Basically because of the frequency used, you get standing waves in the oven and some rotating metal at the end of the waveguide doesn't have all that much effect on those; I see. But Panasonic seem to think it works. Sure, but it's a lot harder to design one what works as well as rotating the food and it's a trivial to rotate the food. Anyone ever compared the two as in how evenly the food gets cooked? Presumably one of the Which? type operations has. When they metal thing had rotated 90 degrees, so has the weave pattern. No, because you get standing waves in the part of the microwave where the food is. Yeah I was (incorrectly) thinking those would change shape with the source moving, but I guess not. Precisely the same effect as if the food had rotated 90 degrees. No, a quite different effect as the food moves thru the standing waves. Please do explain and I will be happy to accept I'm wrong. I doubt Panasonic will though. With anything where you see both offered, there must be good reasons for both approaches and it can't just be habit/tradition when its been going on for 40 years or more now. Price I would think. Maybe. I've never had a good look at how the flatbed microwaves do it. Most likely just put their dead ones in their wheely bin and we don't allow people to put them on the footpath for the council bulk collection in my council anymore, so I have never had the chance to have a look at a dead one. Makes you wonder why we pay council tax when they refuse to collect half the stuff. Ours doesn't refused to take it, you're free to take it to the dump yourself, and pay $25 per tailer or ute load, $10 per car or station wagon and they have 2 or 3 free dump weekends a year as well. You have to pay to dump it?! Yep. You didn't used to, but modern dumps are pretty fancy operations and that's the story they use to justify the charge. But you pay council tax to cover that. No, that only covers whets picked up in the weekly wheely bin collection. Plus they're getting the raw materials! They don't bother to recover those, it ends as an immense mountain in what used to be a quarry at one time. They're conning you threefold! They are use, we vote for ours. Mate of mine was one at one time and he was too stupid to be able to understand that the council charging for stuff dumped means that quote a few choose to dump their **** on the substantial hill at the back of town instead of at the dump and the council keeps howling about that illegal dumping. But that doesn't work very well for those who only have a car with the bigger stuff like mattresses, lounges, dead fridges etc. Find someone with a trailer, they allow those here. They do here too, but most of those sort of people don't know anyone with a trailer or ute. https://www.tiptopequipment.com.au/m...arousel-09.jpg They (for some reason) charge commercial dumpers, like gardeners, tradesmen etc, but sensible tradesmen take the stuff in a trailer attached to their own car then don't pay :-) Or if you go in the last half hour before closing time, there's nobody at the entrance to charge you and you just drive straight in. Ours has a weighbridge you drive over used to charge the trucks by the weight of stuff on them, and the bloke running the weighbridge locks the gate as he leaves. Our council is unusual in that regard tho, most councils here do have a few days a year where they will show up with a truck and pick up the big stuff that's left on the nature strip. Not collecting stuff free is a silly idea Trouble is they had to pay someone to do that. - the poorer parts around here where people don't have cars, their TVs just get dumped on the nearest bit of land until the council comes to collect them. There are very few here with no car, but the renters still dump the bigger stuff outside the place they were renting when they move out of it dies. Mine refused to collect an old portable TV for recycling, Our dump has a 40' container you put that stuff in that is replaced when its full. Why should I drive all the way to the skip just for a 14" TV? Stuff that small goes in the wheely bin fine. https://www.bunnings.com.au/handy-24...e-bin_p4520188 The top is about chest height for most people. We get two of those supplied by the council for free, one for normal rubbish and one for recyclable stuff. Some councils have 3, one for garden stuff too. It went in the normal waste wheelybin, **** them. Its legal to do that here. Not with engine blocks tho. so I put it in the landfill bin and hid it under some normal waste. Would have been funny if the tube blew when it was tipped into the lorry. Our trucks that show up every week compress the rubbish and that would normally explode the tube. Ours compress too, but I don't think they're strong enough to implode a tube. The compression thing is a big thick rubber sheet, probably designed that way so it doesn't jam on uncompressable materials. Ours is a huge metal door that will crush anything except an engine block etc. |

Not one person has put forward any argument for your side. Not one. And as I said, Panasonic seem to think the flatbed system is better. Feel free to argue with their managing director. Good luck with that. I've a Panasonic one for just over three years. It's quicker than its turntable predecessor and I've never had any problems with it not cooking food throughout. I've never had a problem with any microwave not cooking throughout. Conventional ovens are uneven, they burn the outside and don't cook the inside sufficiently. For some stuff like a leg of lamb, you need that effect to get a properly done outside and pink inside that most prefer. Same with steak, hopeless in a microwave. Not that I eat meat, That's why. but I don't see why you'd want uneven cooking of anything. A leg of lamb with a nice crisp brown fat layer on the outside and nice pink meat on the inside is vastly superior to the same leg of lamb the same all the way thru. Same with a rare or medium rare steak. True of meat pies too, you want a crisp crust with cooked meat inside, not the soggy crust you get with a microwave. Meat has already been eaten, I prefer original food. Same with toast, its real toast because it isnt cooked uniformly, its toast because its more cooked on the outside than inside. That's about the only thing I wouldn't microwave. I don't anything that I need a crisp crust on. I eat a lot of what we call chicken pillows and a lot of breadcrumbed stuff too. Those are much better in a conventional oven. Roast potatoes in spades. http://lespetitesgourmettes.com/wp-c...en-pillows.jpg I eat when I'm hungry. I want the food within minutes not an hour. Doesn't take anything like an hour for anything except a roast leg of lamb etc. Potatoes take an hour. Waiting for the food is like being in a ****ing restaurant. Why can't restaurants get organised and have food already cooked? They do, but we call those that do fast food places. But I've never seen a place that serves decent meals (not just burgers) in a decent timeframe. They must know roughly how many of each dish will be ordered, so they could start some off. They do with some stuff like currys etc and pies. And cooking the fish and chips or pizzas doesn't take that long. Kebabs are pre cooked too. Every restaurant I've been to I've waited on average 30 minutes. Does it really take that long to deep fry your pizza ? -- Peter is listening to "The club can't handle me - Flo Rida feat.

Hardly anyone buys beer in those now. Where I live is dominated by Italian immigrants and they use them for their tomato paste and I get them for peanuts from the garage sales now. |

There must be money in anything steel, as there's a scrap collector van round here run privately that picks up for free.

It went in the normal waste wheelybin, **** them. Its legal to do that here. Not with engine blocks tho. Some places won't take the bin if it's too heavy, claiming it would break the lifting mechanism, but I've had mine bloody heavy with plasterboard and rocks and it still went. I actually had to give it a hard shove with my foot to get it to tilt over to wheel it around. so I put it in the landfill bin and hid it under some normal waste.

I think the mistake is that the cavity is not moved in relation to the food so standing waves still exist in the same places and only moving the food relative to those is a true answer to this. End of story. Brian That doesn't make sense. Spinning the pattern of microwave radiation must be identical to spinning the food. In both cases they are rotated in relation to one another. not identical at all. turntables produce much better evenness than stirrers. Both together are best. As I said, it's relative. The food and the microwave pattern are relative to each other. Where the oven is and where the kitchen is don't matter. If you rotate the food, or rotate the microwave pattern, PRECISELY the same effect is achieved. I know you think that, you already said. And as so many have pointed out you're clueless. Not one person has pointed out why one is more efficient than the other. I will, particularly with the microwaves with a built in meat temperature sensor. Clearly a lot easier to do those with the food not rotating. And I can also see why rotating the food gets a more even distribution of the microwaves into the food too. Harder to explain that one tho. I see no way it could be explained. Two objects, the food and the microwave pattern. Rotate one, rotate the other, same effect. But you can't rotate the microwave source like you can the food. Rotating some metal thing at the end of the waveguide the microwaves are coming out of is nowhere as effective as rotating the food as far as getting an even distribution of the microwaves in the food is concerned. Why not? Basically because of the frequency used, you get standing waves in the oven and some rotating metal at the end of the waveguide doesn't have all that much effect on those; I see. But Panasonic seem to think it works. Sure, but it's a lot harder to design one what works as well as rotating the food and it's a trivial to rotate the food. The point they make is you get a nice big space for non-circular dishes. Anyone ever compared the two as in how evenly the food gets cooked? Presumably one of the Which? type operations has. Yes, Which? does it but you have to subscribe. You can pay £1 to get access to a single review (or everything for a week, I can't remember) then just cancel, but I can't be bothered. I did it once before to get a review on a washing machine I was buying. https://www.which.co.uk/news/2017/02...ed-microwaves/ They do tell us for free though that flatbeds start at £59 from Asda, it doesn't say if that's any good though. http://microwavereview.co.uk has free reviews, but not of very many, I can see nothing about them being uneven, but they haven't tested cheaper ones. When they metal thing had rotated 90 degrees, so has the weave pattern. No, because you get standing waves in the part of the microwave where the food is. Yeah I was (incorrectly) thinking those would change shape with the source moving, but I guess not. Precisely the same effect as if the food had rotated 90 degrees. No, a quite different effect as the food moves thru the standing waves. Please do explain and I will be happy to accept I'm wrong. I doubt Panasonic will though. With anything where you see both offered, there must be good reasons for both approaches and it can't just be habit/tradition when its been going on for 40 years or more now. Price I would think. Maybe. I've never had a good look at how the flatbed microwaves do it. Most likely just put their dead ones in their wheely bin and we don't allow people to put them on the footpath for the council bulk collection in my council anymore, so I have never had the chance to have a look at a dead one. Makes you wonder why we pay council tax when they refuse to collect half the stuff. Ours doesn't refused to take it, you're free to take it to the dump yourself, and pay $25 per tailer or ute load, $10 per car or station wagon and they have 2 or 3 free dump weekends a year as well. You have to pay to dump it?! Yep. You didn't used to, but modern dumps are pretty fancy operations and that's the story they use to justify the charge. But you pay council tax to cover that. No, that only covers whets picked up in the weekly wheely bin collection. Plus they're getting the raw materials! They don't bother to recover those, it ends as an immense mountain in what used to be a quarry at one time. If they're not using the materials, then why collect them seperately from the garbage? They do in theory use the stuff in the recycling wheely bins. In theory because china has now refused to take that stuff and its far from clear what we will do about that now. Its never going to be feasible to pay people first world wages to do the separation of the various stuff. There must be money in anything steel, as there's a scrap collector van round here run privately that picks up for free. Yeah, we have one that is happy to accept that stuff, but he doesn't collect it, you have to take it to his place and its well out of town. We have another that is happy to collect dead cars for free. You also have to try to avoid them if you're giving away a working washing machine on Gumtree or freecycle, as they spot your ad and crush them for scrap which is a bloody waste. No one does that here. They're conning you threefold! They are use, we vote for ours. Mate of mine was one at one time and he was too stupid to be able to understand that the council charging for stuff dumped means that quote a few choose to dump their **** on the substantial hill at the back of town instead of at the dump and the council keeps howling about that illegal dumping. So councils are stupid right round the world.... Yep. Right around the modern first and second world, anyway. Its different in the third world where you get plenty who comb the dumps for almost anything and live at the dump. We arent even allowed to scavenge the dump anymore. Used to be able to and when I was building the house I would often bring more stuff home than I took there. But that doesn't work very well for those who only have a car with the bigger stuff like mattresses, lounges, dead fridges etc. Find someone with a trailer, they allow those here. They do here too, but most of those sort of people don't know anyone with a trailer or ute. https://www.tiptopequipment.com.au/m...arousel-09.jpg ****'s sake you just have to walk along a few streets and you'll see loads of trailers. Sure, but few of those have any interest in carting stuff for others. People have them for holidays and all sorts. Camping trailers are no use for moving dead fridges etc. They (for some reason) charge commercial dumpers, like gardeners, tradesmen etc, but sensible tradesmen take the stuff in a trailer attached to their own car then don't pay :-) Or if you go in the last half hour before closing time, there's nobody at the entrance to charge you and you just drive straight in. Ours has a weighbridge you drive over used to charge the trucks by the weight of stuff on them, and the bloke running the weighbridge locks the gate as he leaves. We have a weighbridge, but they don't use it for private vehicles. We just have the one fella who you pay so its easier to have everyone pull up on the weighbridge and just hand him the fixed charge thru the window with cars and trailers that don't get charged by weight. They just check you have a card proving you live in this area when you enter, We don't need to because there are only two dumps for the main town and the surrounding villages and you are free to use whichever dump you like. and tell you which skip to put things in, Yeah, ours do that too. but if they're too busy or are closing up near the end, they just leave the barrier open. Ours doesn't. Its got lights on the runup to the weighbridge and when they shut down they just turn that off and lock the gate as they drive out the gate. Mine refused to collect an old portable TV for recycling, Our dump has a 40' container you put that stuff in that is replaced when its full. Why should I drive all the way to the skip just for a 14" TV? Stuff that small goes in the wheely bin fine. https://www.bunnings.com.au/handy-24...e-bin_p4520188 The top is about chest height for most people. We get two of those supplied by the council for free, one for normal rubbish and one for recyclable stuff. Some councils have 3, one for garden stuff too. Yes I have 3. And the garbage one is where my TV went. Technically that was against the rules, but that's their fault. I did leave it with the recycling box (lightbulbs, glass, toasters, etc). It went in the normal waste wheelybin, **** them. Its legal to do that here. Not with engine blocks tho. Some places won't take the bin if it's too heavy, claiming it would break the lifting mechanism, Yeah, ours does too, but they just put a sticker on the bin in that case. I have to be careful with a bin full of old newspapers, that I don't fill it. but I've had mine bloody heavy with plasterboard and rocks and it still went. I actually had to give it a hard shove with my foot to get it to tilt over to wheel it around. I've only had the sticker once, but that's because I was more careful after that. I got rid of the VW engine and transaxle that I scavenged from the dump when building the house with the street pickup of big stuff before they stopped doing that. I had plans to make dune buggy out of it but never got around to doing that. so I put it in the landfill bin and hid it under some normal waste. Would have been funny if the tube blew when it was tipped into the lorry. Our trucks that show up every week compress the rubbish and that would normally explode the tube. Ours compress too, but I don't think they're strong enough to implode a tube. The compression thing is a big thick rubber sheet, probably designed that way so it doesn't jam on uncompressable materials. Ours is a huge metal door that will crush anything except an engine block etc. You said it's legal to put a 14" CRT in your waste bin, but you also said it would explode with the crusher. Which is correct? Both. It would explode inside the body of the rubbish truck, no big deal. |
