[…{ … what would it look like if you scaled it from zero ? MichaelG.
Both data sets occurred in the same time, but as their dimensions and Y-scales are unrelated, the eye is required to look for a pattern. The pattern doesn't depend on scale and is usually more obvious if both lines use all the space available.
. An admirable reply, Dave … but please let me be the first to bring Politics into this discussion … I am sure I have seen the Liberal Democrats using similar techniques to manipulate the way that viewers perceive presented data.

When one can buy a well made and fairly accurate bourdon type pressure gauge for around 8 US dollars (or your local equivalent) why are we discussing ways for the OP make an inferior alternate? […] . As a disinterested and uninterested observer … I would guess it’s something to do with Model Engineering vs playing with trains. MichaelG. |

Have been to Waterford Crystal several times and was assured that all glass is in house! . Please see my edit, Bernard MichaelG. |

Bernard … I feel sure you are wrong. I paid very little for this ‘pre-loved’ example, but it looks right to me. … By mentioning it, I was simply trying to indicate that what Samsaranda noticed has been going-on for years. MichaelG. .

recently bought [for reasons not relevant here] a long-discontinued Waterford clock … being a glass block with a small Quartz movement inserted. Inspecting the components, I found:

Thread: What grade of aluminium is best for making a pulley? |

Dave warns against 'fabricated' pulleys, but what exactly does he mean by it? … . I suspect that Dave just meant ‘fabricated’ to mean ‘made by machining’ … but only he can confirm or refute that. It is, however quite possible to fabricate Vee pulleys by using two truncated cones … either fixed together or keyed, with an adjustment mechanism. MichaelG. |

I agree with Jason Generalising outrageously from just a single comparison: The textured green belts coming out of China seem to be a very good approximation of the expensive Swiss ones … except in price ! MichaelG. |
Thread: Chester Cathedral : New model railway |
10/08/2023 06:56:22 |
This may be of interest to some I receive an eMail ‘newsletter’ from Chester Cathedral … the latest of which included this: . This summer, discover a brand-new 64ft long model railway created by Pete Waterman OBE and the Railnuts here at Chester Cathedral. For 2023, the Railnuts teamed up with Tom Connell - a transport illustrator - to produce a picture for the event and there's an exhibition of his work beside the model railway. Making Tracks 3 is open from 10am to 5pm Monday - Friday and 10am-4pm on Saturdays. Tickets are £3 per person, using the Cathedral’s summer entry charge, with free entry for children aged 5 and under.

This is not a criticism, Dave … far from it ! But something is nagging me: By [ quite understandably] scaling your pressure graph from 970, are you perhaps exaggerating its significance ? … what would it look like if you scaled it from zero ? MichaelG.

Paul. A napoleon's hat clock is not a loncase. Also as they are usually striking or chiming clocks, I would look for a plain clock ( no strike or chime ) for a beginners progect Roy . I recommended the Napoleon’Hat [sorry, I forgot to mention striking version preferred over chimes] simply because it has a ‘Goldilocks’ sort of size, and is available dead-or-alive at realistic prices. Most are mass-produced items and there is much to be learned by simply dismantling and rebuilding one. This was, I thought, exactly the point at which Paul wished to enter the fray. It’s what I did, on the introductory ‘evening classes’ at Stevenage College several decades ago. Opinions obviously vary … That’s fine. MichaelG. |

To me "A.I." would mean artificial insemination. . You have me utterly bewildered, Rob If you were thinking of ‘Artificial Insemination’ why on Earth did you mention Aluminium ? I tried very hard to answer your written question … but answering the unstated one in your mind is beyond this Human Intelligence. MichaelG. |
