I suspect that the odd size whit tap was used by some manufacturer who wanted to sell spares or service for their product and ensure their service was not easily copied by other suppliers or service providers. I am not convinced that this was always the case. Stanley are often accused of this with the thread sizes on their planes, but they developed the design before thread sizes were standardised and never they changed them. It may or may not have been an advantage with sales, but not the primary reason. |

Note that Libre uses its own format ... Not exactly. Libre outputs Open Document Format, which is non-proprietary. MS-Word should be able to read it. By default MS-Word uses proprietary files, which other software can usually read, but not necessarily perfectly. For ordinary purposes, not doing anything advanced, Libre/Word incompatibility doesn't seem to a major problem. Your mileage may vary!!! Libre (and MS-Word) can both work with a long list of other file formats. Dave One advantage of libre that I found when I was teaching, libre will often open Word files that MS word won't, resaving as word files then fixes the issue for Word. |
Thread: Ether |

Whilst at University we used Ether as a solvent. I can still see the effect of it igniting in the plumbing system of the row of connected sinks. It was a very impressive sight. Luckily it didn't injure anyone.It does need to be handled with respect. |

The thermit reaction was a standard school chemistry demonstration. A piece of magnesium ribbon being used as a burning wick to start the reaction. Not sure if it is still done however.

I have made similar, but cruder router planes with ground allen keys as the blade. |
Thread: I need custard. |

When I was a science teacher, I would regularly use any excuse to explode flour. A good way to demonstrate that food provides energy. There was a knack to getting it to work well. Would blow the lid of a large tin can. |
Thread: 14BA die and 15 thou split pin. |
15/08/2023 18:37:38 |
Thanks for all of the replies. |

Thanks It wasn't really the drills, more the setup to do the drilling without breaking the drills. Keith |

I was at a local steam rally at the weekend. Whilst adding to my collection of taps and dies I noticed a 14BA die. I was tempted to buy it just to see if I could cut a 14BA thread.But I stuck to my shopping list. 12 BA is the smallest I have cut, initially this was a challenge, but I mastered it with practice. Is 14BA a bigger challenge? |
Thread: Grinding wheel bores? |
11/08/2023 18:36:18 |
Posted by Mark Rand on 11/08/2023 16:48:26:
I tend to buy my wheels from Abtec. The 32mm/1.25" thing is a problem. I've been caught out by it before. My solution was to open the bore of the affected wheels with a 32mm Rotabroach cutter, by hand (Que gasps of horror and warnings of explosions by the ignoramuses in the audience). In my teenage years, I opened a green 4" wheel by the very crude method of drilling it out with an old drill bit. This was 50 odd years ago. It still gets occasional use. I am not in anyway recommending this method, but it worked. |
Thread: Oil can O ring replacement |
11/08/2023 18:28:27 |
Thanks Howard. As O rings are cheap I will give it a go, little to lose. Does the ring want to be a tight fit, i.e. need to stretch to fit or as exact as possible. My gut instinct is for it to be tight to give it a chance of staying in place. looking at sizes online I can't see an exactly identical size, assuming I have measured it correctly. |
10/08/2023 20:21:57 |
Some time ago I used an oil can to inject woodworm treatment, this was fatal to the can - lesson learnt! The can has been sat around for some time, today I took it apart. The O ring has gone hard and nolonger fits tightly in its grove on the plastic piston.I tried replacing it but it comes off as soon as I try to push it past the threaded entrance to its plastic chamber. I plastic cap screws in to seal it. Assuming that I can get a replacement ring that fits tightly how do I persuade it to go in without it pulling off. Is there a trick? I assume that when made it must have gone in easily. It was only a cheap can, but if possible I would like to repair it, or am I wasting my time? Has anyone elsedone it? |
Thread: Use of coal, oil and fossil fuels |

Was listening to a piece on fusion today. needs a lot of development, but it was suggested that heat output could be 10x input. just needs investment money to develop further. proof of principle has already been done. Unlike the military use of fission, this can't exist for fusion. |
Thread: Bum deal on Toilet Seats! |
31/07/2023 14:55:28 |
I bought one from screwfix 15years ago, probably around £20 then. £150 sounds a lot, ours has lasted well, but it is a good fit for the pan. |
Thread: Damaged Screws & QCTP help!!! |

I know it is now irrelevant in this case, but as anyone tried using LH drills to remove stuck screws?

This has wandered a long way off topic. Dave I live on the edge of a very rural area. The local politians are doing their best to stop the use of all cars, new and old. At the same time they are closing down the local bus services, replacing them with a half baked scheme that no one understands using transport that can be called by a smart phone. Really they want us to walk or use pedal bicycles. For lots it will take longer to get to the local city than it did 150 years ago. This has nothing to do with engineering. JA
Tend to agree, in all of the the less well off who manage to keep old(ish) bangers on the road will be ignored. I suspect that this will create a major unrest when they suddenly find that they are isolated and denied the services that they are used to. The political fallout could be large. |

My old American lawn mower (no longer used but still in my garden shed) has Unified on the B&S engine and metric on the rest. Can't be to stop you servicing it as manual tells you how to. Its replacement (now also getting old) is all metric. Its manual tells me that it has no user servicable parts, strange how I have managed to keep it going for so long!
