|Thread: Vehi cle Tax Scam|
That thought hadn't entered my mind - t'would need some clever work reprogging the nearby nodes..
..That's what they want you to think....
As you know it's easy to spoof the send address, email adress lists are widely available on the dark web, sending emails is cheap and the evildoers only need a tiny percentage of folk to fall into a trap to make it pay/
The cleverest scam we almost fell for was an official looking letter from Data Protection Agency Agency reminding us to pay our annual fee and send them the money to sort it. The real letter arrived the next day. The con one was 'legal' in the sense that they paid the correct fee for the mug but had added a service charge for their work in so doing. Of course it meant that the Data Protection Agency itself was being hacked for the renewal details of all registered businesses.
|Thread: Are we being listened to on the phone|
1984 already had the concept of a TV with built in camera and mike. Fun sci-fi paranoia films include "Enemy of the State" and "Conspiracy Theory" and the lesser "Echelon Conspiracy"

One should be worried. It's not just Amazon or Google but credit card companies tracking purchase types, supermarkets, Systems tracking your GPS, systems listening for key words and a whole slew of facial recognition following you around.
We've lost much freedom of speech and the latest bill curbs aspects of protest and demonstration...
Conspiracy theorists would argue that these items can be switched on remotely and since 'Echelon; has been admitted to one has to wonder what's the latest incarnation in surveillance.
|Thread: New car - or is it a wheeled computer?|
Wan't there an article on the BBC that from Autumn UK they plan to increase the ethanol percentage in petrol such that pre-2000 petrol cars will no longer run? Aspen in cans would be an expensive alternative for my '94 reg car.
|Thread: Computer Update|
I'm cautious in writing this since it may just be a statistical anomaly. But over many years I have bought several PC's and laptops (business and personal) from the likes of Novatech, PCWorld and a couple from Laptops Direct and the latter never lasted anywhere near as long.
edit: Novatech may be worth looking at as they will sell without an operating system...

|Thread: That little elf under the workbench again|
I've just assembled a metal garden shed for OH and dearly wished I;d had a spring screw holding gizmo ofr the cross head driver I used..several hundred very short self-tappers that were horribly fiddly. But once started it wasnlt practical to stop and hunt one up to fit though with beneit fo hindsight it may have been quicker to make something.
For orthopaedic work there is a beautifully designed sleeve for the driver. The screws are pre-laid out in racks by length and diameter and the gizmo can be simply pushed over the heads to grip the screw and release it as its tightened down
|Thread: Any advice on how to cut/file a 45 degree chamfer on a 1mm steel sheet to EXACTLY 45 degrees?|
I don't know how well it'd work in practice but with only access to rudimentary equipment I'd be inclined to bond the strip of steel between 2 lengths of MDF, say 9mm and make up a jig and fence and run a conventional router with a 90 deg cutter along it. A TCT router cutter should cope with 1mm steel OK in such a sandwich.
|Thread: Brass facing finish.|
I've had similar bands appear on (usually wider) facing cuts and assume it's one or more of the following - a transition where surface speed or cross speed reduces cutter performance , probably due to some subtle harmonic chatter. It may be worth playing with tool stick-out and varying lathe speeds to see if the zone moves.
|Thread: Gravity and Weightlessnes|
More weirdness I was trying to understand recently:
Light has no mass and therefore cannot be affected by gravity. Light can only travel in straight lines in a vacuum except that the matrix it is travelling straight within may be 'bent' by gravity. Therefore the model concludes there has to be some underlying matrix we choose to call space/time or subspace or whatever. Unless it's all a convenience and light can indeed be bent by gravity despite havng no mass...
|Thread: Advice on Heat Treating|
|Thread: Welding and Pacemakers|
A little gallows humour.
I had a client who was an undertaker and kindly gave me a bag of 'removed' pacemakers (in the 90's). I hitched them up in turn to my ECG machine - half were dud...
Joe Pieczynski's latest vid shows a very simple temporary follow steady for fine work he used for threading.
|Thread: I want a telescope|
If it's only for terrestrial work then consider binoculars on a stand or perhaps a spotting scope and camera tripod or an astronomical scope with an inverting lens.
If planning on sitting comfortably then probably a zoom spotting scope on a table stand might suit. Plenty of all these options on ebay for a price guide.
|Thread: Making mild steel look like cast iron|
A salvage yard may have suitable mantles. . When we redecorated a large Sth London property and took down some boxing i found a beautiful marble and tiled fire surround lacking it's mantle. A few calls later and one chappy dropped by and later brought round a matching mantle from the same style of surround.
If the fire is going to be used I'd probablt shy away from an Iron mantle since I'm likely the first guy to grab hold to pull myself up and get burned.
If you can set it up in the lathe then Joe Pieczynski showed a technique that could work demonstrated with a 26thou drill through s/s
|Thread: Skynet is Coming|
Most folk know roughly when they'll be back so a simple timer does that with no risk of being hacked or details of where you work, phone type and likely all your contacts being sent to the washing machine and sold in China...
|Thread: ml10 or some other?|
Other considerations might be that a new lathe will come delivered and with a warranty and phone support. Things useful for a beginner.
|Thread: Guiness world record?|
Lie on my back on the bed and bend knees to put on socks
I do try an do excercises to keep bits working. Rowing machine temporarily abandoned after spraining an ankle - 6 weeks ago and still painful and swollen. But one arm dumbell lifts and presses and pec excercises. If I miss 2-3 days then weight capability drops markedly....
I also practice putting shorts on standing on one leg- balance is becoming an issue but it helps to have the lifted leg swung slightly across the standing leg...
