All that hot air usually exhausted by aerobuzzers being replaced by colder, more dense gases?🙂

The occasional high pressures are likely keeping the wind speeds high - along with the wind-generated leccy?

Yes we have delighted in seeing deep blue skies without the continuous haze of contrails we have all become accustomed to.

It is heartening to see how quickly pollution haze has disappeared from the skies (and we live in Dorset with predominantly Atlantic sea breezes so the improvement must be more marked further inland)

Daily Mirror News feed yesterday - Ghent University Belgium

sorry but I don’t know how to create a link from the news feeds

if you do a Google search on ferrets and Corvid 19 you get a number of hits on what appear to be trustworthy sources - ferrets are used for testing as they are known to be susceptible to this type of virus.

Now on laptop so can quote the link re cat: https://www.mirror.co.uk/news/world-news/cat-tests-positive-coronavirus-after-21770384

so if the roll sits in a vertical holder attached to the floor , should it be unrolled to the right or left of the dispenser?

Towards or away from the pot as it where? surprise

Northern or Southern Hemisphere?

Lets be clear Antiseptic alone is known to be ineffective for this virus. The virus has a coating of greasy protein which is cut through by soap. Then the core (essentially a tiny bit of something like DNA I believe) needs disrupting.

As I understand it Bleach will do this at reasonable concentration, as will Antiviral cleaner (which has degreasant). Not sure about disinfectant but this probably works if it incorporates a grease cutting agent. Disinfectant and bleach however are not suitable for use on skin - they are formulated as strong surface cleaners.

I have been told on good authority that normal household antibacterial cleaners/surface wipes simply do no kill the virus and that medicated soap is no better and is probably not as good as normal soap for killing the virus. (Its medication makes it kinder on sensitive skin not more powerful).

Advice given by Government is therefore correct in saying wash with soap and hot water, throughly and often!

A piece on TV this morning looked at Hand Sanitiser which seemed to work quite well but soap was better if used properly.

We use Isopropyl Alchahol (IPA) as a weak degreaser so it is logical that at decent concentrations it will have an effect - this being the active ingredient in sanitiser gels.It does not however incorporate the other active ingredients incorporated in antiviral products.

Also look at the virus lifespan on different surfaces - for some it is 24 hours, for plastic it is said to be over 72 hours, so safest to leave at least 4 days if unsure.

Have you seen that Cats and (especially) Ferrets have been found to catch Covid 19 also? It is not know if they can then pass it to humans. Dogs have been found to have traces but is thought do not 'catch / pass it on' - maybe contaminated by being stroked with contaminated human hands?

The good news I suppose is that cats and ferrets tend not to sneeze in our faces or kiss us!! Given what dogs roll in I hope most people already wash their hands in between stroking dogs and handing food.

Our local post office, like many others, is in the local shop so it seems entirely reasonable to post parcels while out to get some milk or the newspaper assuming the seller is prepared to go out at all or indeed really needs supplies. As this bites more folk are finally going to hunker down and ration themselves.

PGK

Still creates an unnecessary risk in my view. Too many people are 'trying to get away with it' or failing to understand just what we are trying to achieve.

If you must post items, use disinfected gloves and a 4 day quarantine to ensure packages are virus free but even by going in the shop you risk spreading the virus if you happen to be contaminated. (with this disease you simply don't know if you are)

The longer this goes on the greater the aftermath affect will be on all of us (through loss of those dear to us, to recover lost income and to pay off our share of the National debt)

For now lets focus on minimising interactions and help get this virus under control as quickly as we can.

Thread: Free to a good home

Understood Ian, I am just trying to discourage risk takers.

I also understand your logic and that some activities can be done in both a safe and unsafe manner.

26/03/2020 21:31:40

A kind and generous offer but perhaps too tempting for risk takers.

it is just those risk takers that are putting us all and our dear NHS staff in needles jeopardy.

Let's all be patient, stick to the rules and get through this as quickly as is humanly possible and in that way also minimise misery from loss of life, we can then start to adjust to the new reality.

just glad that 'sheddists' generally have lots to amuse themselves with in the meantime.

Thread: 7 pin connector 240v?

I bought some of the eBay aviation connectors purely because they are so cheap, it would surprise me if they are fitted to aircraft. I would hope to find connectors like the military spec Amphenol on any aircraft I was a passenger in. Do these “aviation” connectors actually meet any specification for aviation use or does it just sound good in a sales pitch? the quality of my purchase was in line with the price paid but they will be ok in the non critical application I purchased them for. Are they a cheap copy of a quality connector or are they just a cheap and nastyish component?

Have you told Boeing? This may assist their investigation!

Thread: Coronavirus

During this sunny weather it is good to get a good dose of sunlight too as it boosts vitamin D - sitting in the garden or at an open window if you are unable to get out in the open away from others.

It is nice to think that reduction in traffic will be making the air cleaner for city dwellers at the time that fresh air is of most critical importance.

Lets also bear in mind the sufferers of tree pollen hay fever as they also will be about to join the group of unfortunates who must particularly dread the risk of Corvid19.

Thread: Silver soldering zinc plated steel

+1 for remove the plating first.

Does it have to be silver solder?

Soft solder takes to zinc and mild steel using Bakers Fluid as flux but of course its a lower strength joint and useless for high temperature applications.

Thread: SRBF/ SRBP/ PTFE/ Wood for Boiler Mountings?
22/03/2020 00:38:50

PTFE gives off nasty fumes when burnt - so avoid use within the firebox but I suggest would make good bushes elsewhere if you have it. Teak or Iroko strips for cladding? (pretty good thermally and don't need painting)

And maybe add to that Isopropyl Alchahol which is what most of the gels smell of. I do believe there is an antiviral additive required and that antibacterial doesn't do what we currently need.

If anyone is unable to buy hand sanitiser, there is a specialist firm down in Dorset who is producing it - Wessex Chemical Factors. I don't mind plugging heir name as I have found them incredibly friendly and helpful and on occasion they have make up a cocktail to suit my requirements (true chemists).

I have just bought 5l of hand sanitiser , 5L of anti bac hand wash and 2L of antibac surface cleaner (to be diluted) for use in the village by people volunteering to assist neighbours. Delivery within Dorset is not dear but maybe worse by courier.

Currently I use their cutting fluids for lathe and mill, car screen wash, workshop hand cleanser (with granules), teak restorer (brilliant for garden furniture), pressure wash cleaning additive and have also obtained oil for Myford, Boxford and Centec lubrication from them (tell them what it should have and they will source the appropriate equivalent)

I think their website is currently undergoing 'redevelopment' so you might need to ring them and maybe request their catalogue.

I can confirm that the active ingredient in Wessex Chemicals Hand Sanitiser is simply Isopropyl Alchahol, presumably there is an inert gelling agent added. They advise that it should not be used as a substitute for soap and hot water washing as a primary defence for the very reasons stated by Simon above. There is good reason why Public Health England have given the advice they have and would all do well to get into that routine. (not easy when accustomed to eating tea and biscuits with cutting fluid under your nails!)

An NHS friend has asked me to spread he word that fuel pump handles at filling stations have been identified as a serious mechanism for spreading Coronavirus so wear gloves and wash hands asap afterwards. (Sadly Tescos have removed the gloves from the courtyard at our store, presumably because people are now stealing them!)

The Antibac surface cleaner referred to above is called AMB Clean and appears to have good antiviral properties too. As sold it is for industrial use but is safe for general use once diluted 1:50 (they think it still works at 1:100 or maybe greater dilutions) It has a complex list of ingredients and cuts greases well. 5L diluted 50:1 goes a heck of a long way so I have shared mine with friends! Not something you would want to splash in your eyes so care is needed, much as you would with bleach. I have diluted 1:3 before passing to others which happens to make subsequent dispensing into 500ml bottles very straightforward as one shot from the dispenser pump is then topped up with water to fill the bottle.

I would trust this product far more than the household cleaners you get in supermarkets which appear to be much simpler antibacterial and mould killing products and are probably of limited use against virus.

I suggest that anyone considering this type of product should discuss its properties with the supplier and satisfy themselves that it is right for their intended use as I am no expert on this.

Only mentioning in the absence of products on the supermarket shelves round here!!!

Thread: Myford Super7 Valuation help
14/03/2020 16:16:31

Just to add that the item to the left of the Rodney Milling attachment in your later photo is a milling table for it so that it can be mounted on that independently of the Myford to give a bench mounted milling machine . Obviously I would need its own motor and the pulley assembly in that same photo looks like a countershaft / clutch assembly from a Myford lathe to be used as part of that process. There doesn't appear to be a suitably sized motor but they are easy to pick up (about half horsepower will do). I would have thought you would get approaching £500 for those items as a bundle if the slides on the table are not corroded and move smoothly. The Myford VMC mill is a later version and they change hands for £700 or £800 in decent condition. I think there is a raising block (square item with four holes) which also goes with it - sits between the Rodney and the bolt holes at the back of the milling table)

Agree entirely with the sound advice others have given.

Hope you have success with getting this to a good home at a fair price, I hate seeing people stitched up in these situations.

Thread: Speedometer Ratios
05/03/2020 18:22:29

Faced with a similar dilemma, but recognising the probable need to calibrate several times with different dis tyres and different ratio differential I elected to use Hall effect sensor on the driveshaft and a digital to analogue converter ( drives a motor which then drives the speedo!)

you can then set it to whatever conversion ratio you require.

Not cheap but the easy solution if you may need various ratios and prefer an original anologue speedometer clock.
