Thread: NVR Switch

often the forward/reverse switch has a centre position to force power off - if the reverse section of this power switch is faulty then might explain it.

well that involving Guy Fawkes was a setup non-event by the rabidly antiCatholic Robert Cecil (Lord Salisbury) - no serious evidence was ever produced at the show trial.

Maybe COP26 is yet another non-event ?

the use of 'x' as a contraction for hard 'c's or 'ks' at end of a word is an 18th C innovation - eg Manks became Manx gradually over mid to late 18th C
Thread: How can I make an accurate 90 grind using a diamond whetstone?

I have a ready supply of 0.5mm x 8mm x 48mm strips - one can indeed set a small magnet on the rear face of a strip laid horizontal then balance one strip on the 0.5mm face on the base strip and even balance a 2nd strip on its 0.5mm face on the other edge of this balanced strip - the strips are the lamination strips found in a low voltage transformer with the usual E+I arrangement - I now use them as packing strips under lathe tools - may a slight adjustment as to size will allow these accurately formed and magnetically suitable strips to be used in any demonstrator (The winding & E laminations were used in a demagnetiser)

is SBK the name of a commercial product or some as yet unexplained acronym?

another recommendation for Vuescan from me - made my old slide scanner usable under Linux and produce very acceptable images whereas the company offered no updates to their XP driver.
Thread: pdf's increasingly flagged as 'dangerous'

most I think are because they are http rather than the latest https - for those on landlines it is highly unlikely that the link will be tampered with (ie be insecure) but for those using mobile phones via base stations in cafes etc that will not be the case - Firefox has become much more link security conscious recently
Thread: Microwave Oven
25/10/2021 17:35:50
it would have to be a very old microwave oven to have a transformer in it - modern power supplies are much lighter and very much cheaper.
Thread: Selection of AC transformer for Align Power Feed

the 110V site transformers are true transformers - the secondary is centre tapped with a connection to earth thus maximum 55V supply which is considered safe.

I have an old PF3600 scanner that produces a 12MB jpeg image with autofocus and tho better than needed for use on a laptop etc is still nowhere as good resolution as the original slides (admittedly taken on a good camera with good lenses) - I bought a couple of cheap scanners but these produce poor quality as well as being poor to focus - you will definitely be disappointed with these.

Tho the slides had been kept in special folders they still needed air brushing before scanning - a relatively slow business as each slide needed to be handle individually - I did 3000 over a period of many evenings (+ two bottled air dusters) but still have probably another 5000 to go.

The other key point is to create a data base as you scan - luckily many of my slides had some title written on the slide frame - otherwise you won't be able to find them again.
If you have access to a good quality scanner these often had an adapter to allow scanning of slides - slower process than a special slide scanner but in past I've had reasonable results from such a scanner.

actually if you read any 17th or early 18th century handwritten documents you will find many variations in spelling - several of which were adopted by the American colonies.
Thread: Flexispeed Lathe

just use a M6 screw as a simple gauge
Thread: Walker Midgley Prize Draw for Model Engineers
06/10/2021 19:32:33
actually compared to many Social Media sites found on the Web this site is generally free of paid 'influencers' and fairly free of adverts and unlike too much of the web the posters usually are knowledgeable - that effort of Walker Midgley is fairly amusing being so blatant as for ?100 they hope to get a good number of home phone numbers, addresses as well as what insurance is held - even M & S have a go at this with their 'how did we do today' offer.
Thread: M6 thread locking/stiff screw

I have some fishing line - comes in various thicknesses (usually expressed as breaking strength or weight of hoped for catch) - any shop that deals with fishing tackle will stock it
Thread: Material selection or additional process

maybe the steel was the same 'metal' used in the set of Poundland allen keys bought out of necessity as no hardware shop was in locality and I needed one of the small ones to remove a grub screw - it twisted like a corkscrew and job had to wait for me to return with a proper set of keys.

my GP surgery won't accept emails - has a very poor web interface and telephone calls take ages to be answered and only after one has listen to (and paid for) a long winded explanation as to how qualified the secretarial staff are in triaging. Personally I write a note and drop it thro the letter box marked specimums.
Thread: What Did You Do Today 2021

I would have considered placing lathe and mill on same wall esp if the room length is suitable as it allows easy access to the headstock to allow use of long lengths thru the chuck - they can be set up to 'dangle' over the mill bed - even easier if you build a extra steady that sits on the mill bed - avoids much wastage if you only need short lengths for items.
Thread: Disc drive - Anything useful inside ?
20/09/2021 19:07:58
the tiny screws, two powerful but awkwardly shaped magnets, a couple of small bearings - I believe, but haven't done it myself, that the alloy case can be melted down.
The actual disk platter is extremely accurately flat but never found a use for it - the first generation disc drives used a glass but later ones used metal
The small motor driving the platter can be removed but you need the extra electronics to drive it

Waterstones now charge 10p for a paper bag which seems to either be sheer profiteering or a sign their finances are poor - at one time Waitrose used cloth bags (still have one as spare bag in my car) which last for some time.
Thread: Extension to Digital Version

I have a print subscription for MEW but after the confusion re the number of issues promised under that subscription I decided to have a standing order with local W H Smith in UK to take ME and hold it until I collect it - that has been erratic with both that and for another weekly magazine I take missing issues etc - my own opinion is that W H Smith don't actually care though they require an upfront deposit to hold magazines.
So far I seem to have all MEWs tho as many have realised the contents seem significantly less than pre covid days and with sometimes poor proof reading leading to missing content.
I don't find reading issues online attractive though it does save considerable space - the surveillance model of today's internet is equally distasteful.
