I have often wondered why no one has designed a mobility scooter that can be towed. I suspect that some of the reasons have been aired above. |
Thread: carbon or HSS |

Am I to understand that the Tap and Die Company don't actually sell HSS taps, and that all of their taps are made of "HQS"? If that is the case, I hope I'm not being overly cynical in tentatively concluding that they're selling what are essentially carbon steel taps (good ones, maybe) whilst trying to claim they're in a special qualitative category that puts them (implausibly, in my view) above more expensive HSS taps. I've not actually checked that their HQS taps are cheaper than typical HSS taps, but I assume from Peak4's quoted blurb on the first page of this thread that they are.

Thanks for all of the replies. My collection is made up of new ans secondhand (many as new). I don't really use them enough to be a good judge. At my age I am tempted to buy carbon. I have only managed to break one carbon tap. A 12 BA that I was a bit heavy handed with whilst using freehand, If I remember correctly it was a cheap one that I bought from Props at a show. I have also broken brass in a M3 die, trying to cut a brass rod that was greater than 3mm. I put both down to experience. |

I need to add to my taps and dies. Carbon ones are obviously a lot cheaper, what are the disadvantages. My initial thought is to buy carbon ones from Tracys. But I noticed that the Tap and Die co sell what they call HQS ones. Is this just their name for carbon? Has anyone used both firms, how do they compare. |

According to a university in California grass is better at sequestering carbon than trees. Eventually trees either die, fall down and rot away or catch fire and burn away. Either way the captured carbon is released back into the atmosphere, whereas grass creates soil via its roots and that is permanent. As a by product you can have meat. Ploughing to grow cereals and vegetables releases carbon fom the soil, you don't have to plough permanent grassland I am curious how grass creates soil? If you mean the organic part, so do trees, just walk into woodland to see it. |

Cloud cuckoo land. I am a huge advocate of green tech but some things are just not achievable or viable at the scale they advocate. Growing stuff to burn or bio-digest it at the scale of our enormous consumption of fossil fuels is hopeless, for instance we have to import wood for Drax, we can't even feed one wood pellet burning power station, let along six. Move the playing field, bio-digest waste and use wind and tidal power for the bulk of our energy needs and there may be an argument, but to use valuable agricultural land to grow fuel is wasteful when so many people in the world are hungry.
We already grow wheat to make bioethanol to make up 10% of E10 petrol. |

Using agricultural land to produce ........... However, if we get to the position of producing an excess of green electricity, this could be used to hydrolyse water to produce hydrogen (and oxygen) to provide a clean fuel. Or just use the excess of green electricity... The point is that it is in excess of what is being used. As I understand it wind turbines are paid not to produce energy when it is not needed. It makes sense to use it to produce an energy source that is storable, rather than not use it. The problem with light and wind energy is that production is not consistent with use. |

Using agricultural land to produce energy reduces the amount of food that we can produce, so solves one problem by creating another. For too long finite resources have been assumed to be infinite. The real problem is always ignored, that there are simply too many people trying to consume these resources. However, if we get to the position of producing an excess of green electricity, this could be used to hydrolyse water to produce hydrogen (and oxygen) to provide a clean fuel. |
Thread: BA Spanners on Metric nuts |

Although I have a good selection of Whitworth, BA, AF, Metric spanners and sockets, and even my dad's old magneto spanners, I also have a selection of adjustable and stilson spanners. I know it will upset some but I don't have a problem using adjustable spanners, especially on small sizes. |

Whitworth did go down to 1/8”, I have a tap inherited from my father 1/8”BSW x40tpi. BSF stopped at 1/4” but it seems that taps do exist which are either not standard or maybe the standard included them as non preferred sizes. My father gave up toolmaking in 1952 when recalled to the RAF so the tap is rather a vintage item. Mike Mine go down to 1/8", but you can buy them down to 1/16". |

When I read about not getting the ring shank screws in the wrong place, it seems that stainless steel wood screws would be a better option. |

Apart from the issues fixed as mentioned. As far as efficiency is concerned there will be an RPM where the IC engine is at its max efficiency. If the vehicle was designed to run at this constant rate then as the rotary to electrical conversion efficiency will be high the energy extracted from the fuel will be better than the IC engine alone. Typically battery sizes for hybrids do not require such high capacity as EV's so are lighter and as has been said harvesting energy from regenerative breaking pushes the efficiency even higher. So it helps with the urban pollution problem and uses less fuel.(The Yaris gets 60mpg compared to my fiesta at 50mpg) Apart from that yes you are right it solves nothing. regards Martin My Honda Jazz averages pretty close to 60mpg. once warm the engine switches off when not moving. with the price differential, i would want a hybrid to do much better than that. |

Installation of new gas boilers would be banned and heat pumps used instead. Stuart
Except that as I understand it for most not well insulated home they don't provide sufficient heat. Edited By Keith Wyles on 22/08/2022 18:47:47 |

Dave. Is there enough generating capacity to replace what is being removed to satisfy this "need" you speak of? If not, then what's the upshot for the average citizen?
Martin.
It is more than just the generating capacity, it is the ability to transmit the electricity. as I understand it there is no spare capacity in the national grid, so it will need upgrading. |

i have read the article and found it of use. A cost comparison of different ways of reroofing would be helpful. i have always refelted using heavy duty felt. But have seen others use corregated plastic coated "tin" , bitumen or plastic, often on top of the felt. |

Just to break into the "is it isn't it" argument regarding climate change. As engineers with your Health and Safety hats on you should be aware that Risk can be defined as the probability of an occurance multiplied by the loss or damage the occurance causes. In the Climate change scenario Loss is rather large, half the word uninhabitable, widespread famine, water shortage and possible total breakdown of civilisation if not human existance. For such a massive loss the probability needs only to be even very small for the Risk to be enormous. (Personally I consider the risk to be totally unacceptable.) So even the most died in the wool climate sceptics would consider the probability to be non zero even if they feel it's a low number and for the rest of us the probability is somewhere approaching 1. So even with a low probability with such high damage are you still prepared to bet the farm. regards Martin Won't this solve the problem? Less people - less polution. probably the only likely solution that is going to reduce CO2. |
