Thread: 12V Motor for a Top Slide Drilling Attachment |
18/03/2021 08:13:54 |
Here's my quick and dirty attempt:
a 500w ER11 spindle motor, clamp, power supply and collets from Ebay for about £90. There's a 10mm square bar screwed to the back of the clamp to fit a QCTP holder. It drops into place just like any other holder, and easily crossdrills, face drills off centre and mills slots like this fluted knob that I prefer to knurling I also tapped my vertical slide for it, but that's such a faff to install that it's going to be more use for jobs like gear cutting if I ever get around to making the clock I've been considering for ages. |

Posted by SillyOldDuffer on 14/03/2021 10:09:27:PS. Reading the book, which is about values and the 'Metaphysics of Quality', I found the first half delightfully readable but the second half blew my mental fusebox. It plunges deep into the meaning of 'quality' and is too hard for me: I'd be grateful If anyone can explain part two in simple terms!
It's utter drivel.
Is that simple enough? Either that or you don't understand it. Bit like the Romantic with the left hand thread that SOD mentioned. I had the same thing when we studied metaphysics at school: it turned out to be a very complicated way of describing/explaining simple things, with little improvement for the effort. |

Has anyone still got a copy of the "Management Sentence Compiler"? Three columns of words where one word from each column, chosen at random, could be placed into order in a sentence which seemed to make sense, but actually conveyed almost nothing. It was a splendid means of writing a wordy, but nonsense reply to almost anything. An example of "blue sky" thinking no doubt!
The government has been using it for their Covid policy and general slogans for at least a year |

You can get reinforced similar to the Speedclic ones, but without the proprietary fitting. They last almost as long, but are a lot cheaper. I find that Dremels are one of those tools that seem like a good idea, but are not much use in practice. Especially if you're using them on steel. |

Posted by Hopper on 12/03/2021 08:03:54: Salted ice will get down to maybe minus 5 degrees. But it acts so slowly, compared with nitrogen or oxy/propane torch, that the temp differential between the bearing race and the surrounding metal will be minimal. Same with installing bearings. You can heat the housing, especially aluminium motorcycle crankcases etc, with a propane torch to 400F and bearings will fall in and out almost by themselves. But freezing a bearing overnight in the fridge make no noticeable difference to the fit. There just is not enough temperature difference. I'm glad you didn't tell me that before I tried it! I've done several rear wheel bearings on Vauxhall Omegas and can tell you that if you place the bearing after a night in the freezer it goes about 2/3 of the way in(they're 47mm thick) with a single blow from a large hammer. After that it won't move without a press or forcing tool and a lot of effort. Glad it worked for you. It has never once worked for me. Maybe it was a very light press fit. Lowering the temp of steel by 30 degrees C in the freezer compared with raising an aluminium or even cast iron housing by 200 C is chalk and cheese. Could do the sums but its too late at night here. But even in steel/iron you will get about 6 times the thermal expansion with the torch as you will by freezing according to those temp changes.. Then there is the greater coefficient of expansion of aluminium to add to it. But hey if it works, do it!
The effect is small, but obvious. It's very short lived, which I suspect is due to the small temperature difference. But then I doubt that dunking a double row bearing in liquid nitrogen will do it any good.... |

Many of those phrases can be erased from a sentence without changing the meaning, but a huge improvement in readability - going forwards, solutions etc. One company I worked for had a surplus of middle-managers with no real work to do, so we had a constant stream of stupid ideas, U-turns and appalling English. A few come to mind: They were so susceptible to meaningless gibberish that we guaranteed to get it repeated back to us by the end of the week. Our record was the same afternoon Our depot manager returned from a meeting/bollocking/indoctrination session at head office with some shiny new phrases stuffed into his tiny brain. Tony and I had very low tolerance for such things, so we handed round some Bullshit Bingo sheets before the meeting started. He'd used them all in under 10minutes, and that's how long the meeting lasted. The sulking went on a lot longer....
Tony cut another meeting short with the immortal phrase "If you empower me to do that, I'm going to punch you"
Some genius decided each department should write its own mission statement. There was a lot of moaning from everyone who had that dumped on them. I submitted "Arbeit macht frei" as ours, and the subject was never mentioned again.

Are we discussing the sort of language, or the usage thereof, up with which Winston Churchill would not put?
Yes. Although that quote predates him, it shows how daft complaining about split-infinitives is. |

I don't think that anyone has mentioned split infinitives so far. When I was at school, so to do was to incur the English teacher's wrath immediately, but nowadays there seems to be competition between reporters as to who can split the most. What are people's thoughts on this? Is a split infinitive really so bad? It's another invented rule, from people who learnt Latin grammar and arbitrarily decided it also applied to English. Consider how tortuous sentences appear when rearranged to not split the infinitive. |

I was taught the following: "there is a number of items" is correct , "There are a number of items" is not correct because there is only one number. But I see the second incorrect statement all the time. Was my teacher wrong or has the language changed? Colin No, you are correct - number is the subject of is in that sentence, and it's singular. 'There is a number' makes sense, whereas 'there are a number' clearly doesn't. Your second phrase does still convey the meaning which is one of the things that makes English tricky to learn, and drives the pedants crazy. |

I came on here today to read a particular thread, but having read all this great funny one. Iv forgotten what it was...... I was always taught never start a sentence with “and”....... or am I the dolly old duffer? That's one of the invented rules. It's a good idea not to start a sentence with a conjunction very often, but that's a style criticism not grammar. It does require reading and editing your own text, which seems to be rare when you can bash out a couple of hundred words, press send and do something else.
I wonder how Nigel wrote his 'coherent prose without breaking any rules' if he wasn't taught the rules? They never explained the rules of cricket to me, so I spent one summer afternoon a week dodging the missiles that occasionally came flying my way. I certainly wasn't playing the game.
We learnt about nouns, verbs, adjectives, tenses and basic parsing of sentences in junior school and were expected to correctly spell words we used frequently. More technical grammar was taught at senior school, under the reasoning that we would be able to write and speak clear, concise English if we knew how it worked. That's how I learn things today, 32 years after leaving school. |

Posted by Bazyle on 09/03/2021 18:55:06: On radio 4 pm this evening there was a feature on the 'excessive' and "complicated" English grammar being taught to 7yr olds. I never had any of that. Not one iota << note use of latin, I did latin grammar but never realised English had grammar too. We just picked up how to speak and write it by experience. Never understood how people can justify going to University to study their native language as it seems cheating to 'learn' what you already know, unlike Sciences where every day involves being taught stuff you don't already know. Grammar is the underlying structure that makes languages work. Knowing that makes using the a language precisely and accurately much more likely. To continue your analogy, would you expect a physicist to do the necessary maths without a good understanding of trigonometry? Or a builder not to understand why foundations are built that way? I do agree with you that the level of grammar taught to 7yr olds is probably excessive, but learning why one sentence works well and another doesn't - for example - can only be a good thing. We were taught such things at my junior school, over forty years ago, so it's hardly a new idea. |

Just because someone is grumpy, pedantic, opinionated and argumentative doesn't make them wrong. Just hard to deal with. Funny you should say that - my wife says exactly the same thing about me! Yes, me too. Although I don't have a wife to do it. |

Going back to Tom's original complaint: many of the posters here are grumpy, opinionated, argumentative and pedantic, and the phrase 'model engineering' is a terrible description. But unfriendly is a big stretch. Well let me tell you, whether you want to hear it or not (and I'm right about this), you should have used double quotes, not single.
That's a style judgment, not a rule. And many grammar 'rules' are nonsense invented by people trying look clever. I could have used italics, or emboldened the text. Like all of these judgements, the thing to do is pick one, and always use it. I went with single quotation marks because each is one keypress, not two. |

I think parking mouth down was to ensure that if anyone was up in the bell chamber doing some maintenance they wouldn't nudge a bell and have it swing uncontrollably.
That's definitely one reason. The bells in our church park mouth down so that the clock hammers can hit them when its chimes and strikes. There are wires to pull the hammers off the bells before rotating them to mouth up at the start of ringing. Lets not forget the idea of leaving a large weight resting against a 50x50 stick of ash. Or the even smaller peg screwed to the bottom of that stick if you're afflicted with Hastings stays.
Ringing them down is the simple, common sense(that dreadful phrase again) way of preventing problems. |
