Thread: On a lighter note - Are you an interior or an exterior type.
29/03/2020 00:15:25

When I read the title I thought the thread was going to be about how we're coping with being kept indoors. For the record, I'm an interior type and would very readily turn into a 'house human'.

Anyway, I've been told that if you have a cat it is wise to hang the tail of the loo roll against the wall, as the cat can't so readily unspool it all.

Thread: Myford serial numbers and dating for the ML1, ML2, ML3, & ML4
28/03/2020 15:12:37

A nice idea, Jon, and I wish I could help. As far as I know Myford didn't number the early ML1234 lathes (my ML4 certainly has no number) and I've never heard that they kept a record of the later, numbered ones. There are some distinctive changes which can give some guidance, but again I don't believe Myford kept any record of the dates.

I shall watch with interest!

One of my favourites is a series on Youtube called 'Project Binky' - readers of Terry Pratchett will understand - where two, um, enthusiasts are trying to shoehorn a turbo-charged 2 litre 4 wheel drive power plant from a Toyota Celica into a 1980 Mini. I'm not a rally car enthusiast at all, but it's kept me hooked through 28 episodes so far. Lots of very dry humour and some very impressive engineering.

Bob, your reliable informant obviously hasn't done this simple search for 'Martinelli phone virus', which brings this up on the Hoax Slayer website: (sorry this is a bit shouty but I can't work out how to use a smaller font)

‘Martinelli’ WhatsApp Video Hack Warning is Yet Another Hoax

written by Brett M. Christensen July 30, 2017
Hoax Alert Speech Bubble

A message currently circulating via WhatsApp warns users not to open a video called “martinelli” because it will hack your phone in 10 seconds and you will not be able to stop it.

The message asks that you pass on the information to others so that they can avoid the threat as well.

The message circulates mainly in Spanish but some poorly translated English versions have surfaced as well.

However, the warning is just another silly Whatsapp hack hoax. There are no credible references to a security threat like the one described.

Spain’s Policía Nacional has debunked the message as a hoax via its Twitter feed.

Another, very similar version of the hoax warns WhatsApp users not to open a video called “Popcorn Carnival”. In fact, the hoax is just one of many silly hacker and virus hoaxes that have circulated in various formats for years.

If you receive this false warning, do not spread the hoax further by sharing it. And let the person who sent it know that the message is a hoax.

Note that, while these messages are hoaxes, WhatsApp users should be wary of fake notifications promising app upgrades or extra features. These are scams designed to steal personal information or distribute malware.

Example of the hoax:

If you know anyone using WhatsApp you might pass on this. An IT colleague has advised that a video comes out tomorrow from WhatsApp called martinelli do not open it , it hacks your phone and nothing will fix it. Spread the word. Now said on the news this virus is difficult and severe Pass it on to all.

Warning from An Garda. An IT expert has advised that a video comes out tomorrow from WhatsApp called martinelli do not open it , it hacks your phone and nothing will fix it. Spread the word

Tomorrow comes a video for whatsapp is called martinelli do not open it hacks the phone in 10 seconds and you can not stop in any way pass the data to yours and friends

Now then PAT testers and electrical engineers, shame on you! Given this appliance is fitted with an obsolete plug (phased out by BS1363 since 1947) and has wiring in bad condition, why is it OK to simply replace a 5A fuse with a 13A? I suggest James has more to do!

Shame me all you like, Dave; my shoulders are broad. I was responding only to the question about the fuse. Since the original poster had already mentioned that the wiring is in bad condition, I gave him credit for having the nous to get it sorted without my input.

By the way, I have a 10A BS 1362 fuse if you would like it to complete your set. Yellow, if memory serves without checking. Swap it for a 1A?

James that looks like a very old 15 amp plug, went out with the ark. I should replace it with a new 13amp plug and fuse and try that, hopefully all will be well.

Take care

Trevor, the 15 amp round pin plug is covered by BS546 and still used in stage lighting and other specialist applications, though that individual plug is certainly showing its age.

Otherwise, I agree with everybody who says that a 13 A fuse will be appropriate, as long as the mains lead is 1.5 mm2 or 2.5 mm2 (sorry, can't do a superscript 2 for squared) . Even a 13 A fuse may fatigue and fail in the long term (months or years according to use) because of the repeated starting current, but that isn't an issue - just replace it. If it fails in the short term, there may be other issues.

I get more than enough on the news, Dave. Perhaps it was finding it here where I had sought refuge that sparked me up.

In the sixties my brother had neighbours who regularly got into plate-throwing shouting matches, though not as far as I know in the middle of the night. He bought a copy of Good vibrations by the Beach Boys, and when they got going he put it on the stereo and turned it up. After a few applications they would quieten down in seconds!

Steve attracted some rather ‘assertive’ comments on this thread [nudging towards ridicule and abuse], ..

I was irritated by the fact that the headline "Internet Crash" (which looked like something important that I should know about) didn't match the opening post of the thread (which was all rumour and supposition, of which we have more than enough at present).

Many commercial websites are littered with what are called 'clickbait' headlines and are rightly held up to ridicule. In this case I plead guilty as charged concerning nudging toward ridicule, but not guilty of abuse. In mitigation I would put forward the fact that I have had a hard life, and am now metamorphosing into a grumpy old man. I await sentencing.

... ‘Fraid you are ‘teaching a granny to suck eggs’. ..

Or as somebody else elegantly expressed it:

Teach not thy parent's mother to extract

The embryonic juices of an egg by suction.

That worthy lady can herself the feat enact,

Quite irrespective of thy kind instruction.

I watched the first 2+ minutes and nothing useful or interesting was said or shown. I'm afraid I haven't the time or patience to watch the remaining 12+ minutes.

However, some of the posts in this thread are really informative. Thanks.

Thread: screw type abbreviation

Posted by Howard Lewis on 25/02/2020 17:58:13


UNF = Unified National Fine

UNC = Unified National Coarse

UNEF = Unified National Extra Fine.

A lot of people think so, but this is from an American source:

" Some confusion over the UN designation exists. Some people think it means Unified National based on the fact that three national entities came together to unify their thread standards; thus: Unified National Screw Thread Form. By reading the [standard] B1.1 this is not supported; rather UN is the abbreviation for UNIFIED."

I think the 'National' is a hang-over from the American National series of threads, which was replaced by the Unified Thread Series in 1949.

BSC (sometimes called BSCy) replaced CEI threads (Cycle Engineers' Institute) in 1950.

British Standard Brass thread is not a British Standard...

It's a shame we're just past Valentine's Day because here's a handy sentiment to go with a box of petrol station chocolates: "Darling, your lips are like petals. Bicycle Petals."

Also, did you know St Valentine is the patron saint of Greeting Card Manufacturers.

And your skin... your skin is like peaches... football peaches.

This topic has been discussed endlessly in multitudinous places over the last century and a half, and nearly everybody who has an opinion disagrees with everybody else because their opinions are different and therefore wrong.

My opinion, for what it's worth, is that the early bicycle makers found that one pedal repeatedly unscrewed and dropped off. Being practical folks, they tried using the opposite thread on the offending pedal and found that it cured the problem. And that's all.
