Many years ago a convincing documentary "proved" the moon landings were faked. Such a secret could not have remained confidential. Many hundreds would be aware of the scam - set designers, NASA control staff, cameramen, tracking stations, lunar rover manufacturers, etc etc etc. The climate...

I had the joy of a 1967 Skoda 1000MB early in my motoring career. Bought because was cheap and better equipped than an earlier Ford Anglia which had gone to rust bucket heaven. The worst car I ever owned. The only way to reliably get it started was to hook up 2 batteries so the starter motor...

I find this the most convincing argument I have seen for sharpening both sides of the edge to a similar high level of fineness.

There are ~30m ICE cars registered in the UK, 65% of which are more than 5 years old. There are ~1m EV cars registered in the UK, nearly all of which are less than 5 years old. That ICE repairs and spares infrastructure is currently far better than EV is hardly surprising. In 10 years time...

That the EV evolution started mainly at the premium end of the market is no surprise. Initially EVs were uncompetitive in price sensitive markets simply due to battery cost - the cost of batteries 10 years ago were ~$500 kwh and have fallen to ~$150 kwh. Additionally folk with more limited...

Two wooden wonders stand out: WW2 Mosquito aircraft - notable for its largely wooden airframe and skin. This was not a WW1 like biplane with a top speed of 100mph, but a 400mph high performance twin engine plane with a range of 1500 miles and a 1800kg bomb load Marcos Cars manufactured high...

We modify our environment in all manner of ways to optimise our life experience - we: plant gardens and rip out weeds. dispose of part worn clothes and furniture because we want this years fashion and design. buy new cars because the old, despite being functional, doesn't have the desired...

EV batteries are typically guaranteed for 8 years and a minimum of 70% capacity. Tesla claim a typical loss of 12% after 200k miles. Reports by Which (consumer mag) estimate an average loss of 2.3% pa - although in more recent EVs the rate of loss has reduced. I have no doubt there are...

Think kitchen corner units - there seems two main options: access to the end of one unit is seriously compromised as it uses only a single door a two door solution with each opening independently or hinged together. It is then possible yo access the back corner easily Both solutions benefit...

I think this a very good point - to work using the fibres in the optimum way to impart strength to a joint or structure. Our forbears intuitively knew this - in boat building and wood frame buildings where the use of naturally bent or curved wood which followed the grain was clearly preferably...

Rats, amongst other urban pests, are vermin. Unpleasant visitors. Breed rapidly, cause significant damage. Rather than debating the legality of their release, I would be more concerned to understand if legislation prevented their quick dispatch.

Even accountants (of which I was one) may recognise the attraction of being able to market a machine for which reviews consistently praised the quality of the blade included. The clear benefits - (a) it represents a competitive advantage, (b) the brand reputation is enhanced when the buyer...

Main difference will be that with a butt joint the end grain will be on show. With a mitre joint the edge is all with the grain - but uses more worktop to cut the diagonals.

AIUI the arbor is just a tapered interference fit into the chuck. In principle if assembled correctly it should not come apart easily (if at all). A few hundred grams of steel heading towards ones head is not an attractive prospect. Question - what cause the arbor and chuck to separate -...

To accurately tension the chains a turnbuckle would allow infinite adjustment. Like this - but sized correctly

I get a few scam calls - there is obvious pleasure to be had in wasting their time. Sadly it would also waste my time - and I have better things to do. My style, once I know who they claim to be, is abrupt - banks, pension, insurance etc which sound plausible I contact directly. The rest are...

I had considered a sacrificial top for my workbench - then realised the dog holes would need to be redrilled - compounded by the fact that once the top was on I would be unable to easily locate them.:):)

Looks very much like a woodturning beading tool Sorby Not quite as pretty as the £200 set from Sorby and possibly a one off workshop grind.

Were they bookmarked I would expect the grain and figuring to meet in the middle - is one board upside down?

There are some very basic concepts over which greater clarity is required. Efficiency expressed in financial or environmental terms will not always align. An example - PVs have far less impact on climate, yet cost more than gas generation. Improving insulation/controls will reduce energy...
