  1. Extremely sorry to hear of Gregg's death.
  2. Al was an instigator of many an interesting thread..The "japanning" ones were classics.. RIP Al.
  3. BTW..I'm not French..but I live here now.. I've lived in the USA..( beginning in the early 70's ) and in many other countries..( about 23 last count ) With all races..all races are equal.. Your problems, and those of other countries , are brought about by your / their beliefs in non existent gods..whose "prophets" tell you that some are more equal than others..all religions do this.. That is what is wrong with this world..and what has always been wrong with this world..since some decided that they could gain power by convincing the gullible that rainbows and thunderstorms were "the gods"..and that only they could intercede and interpret, that they knew "the truth".."the word".. I know exactly what I'm talking about.. I don't hate DT..he disgusts me..as do many others like him..all over the world..especially those like him..who manipulate people like you..who "believe" what they are told to believe by their priests, preachers, shamans, rabbis, imams etc ..rather than question and think..and accept..there is no god..this is it..there is nothing "after"..no heaven..no hell..no sky fairy watching out for you..no-one listen to your prayers..which is why there are no amputee."miracles" whose legs or arms grow back because of prayer..The bible ( old and new testament ) and all the other religious books are just written scams to get the gullible to do what the scammers want them to..and to keep the scammers fed, and in wives ( the more and the younger the better ), and limos and houses ( or the equivalent in their times ) etc. Be nice to each other.. The only hating / stealing is coming from Trump and his supporters..He is not anyone's "friend", he never has been..he has only ever been thinking of himself..
  4. Making an exception to "My last post here "..I agree totally with Constabulary :) ... Doing "the happy dance".. Congratulations Joe and Kamala..and America ..and the world.. re the replies to Constabulary.. They prove..yet again.. *You can't fix Racist..you can't fix Stupid..you can't fix Misogynistic..you can't fix Psychotic.. There is no God..there never has been.. But if you can get someone to believe that there is a god.. *see the above line.. They'll buy into any crap , accept any scam, any sky fairy tale, that suits their prejudices etc*, that you can sell them.. Or maybe you'll just be content with the power over their thoughts and actions..and your power especially over the thoughts and actions of the intelligent non believers that your laws can impose upon them.. jetemmerde.com ^^^ mine Be nice to each other..just because.. Or send Checks..Cash..Money orders, put Money in the Collection Plate....Buy Tshirts..Hats..( especially red MAGA ..hats made in China.. )..Just do it now.. Our operators are waiting for your call..all credit cards welcome..easy payments are available..
  5. +1 . Mike, what's the point of talking as if we're all bio chemists? If there's a mask pattern that we can make that works, show me the pattern. If there's a bottle of something that I can soak the mask in, show me a bottle label to look for and where to find it. If I need to add this to that then show me two bottles with labels. toxo.. It ( the pattern ) was linked to in my first post in this thread..a tiny effort on your part and you'd have found it. If you were all bio chemists what I have posted, would have been posted, in far more complex language / terminology..I have simplified it ( the overall subject ) as much as I can into "layman's terms" and, as a result, of that , and the fact that I'm posting whilst making masks, dealing with the fact that my wife who is in daily contact with covid 19 patients knowing that she might die due to this contact, and is coming home knowing that she might infect us and that I or our son might die from that infection..Means that I'm aware of many errors introduced into my posts due to this stress and lack of time ( such as describing N-95 type, the type known here as FFP2 masks, in terms used for surgical masks, the folded paper type* )..But the words were short enough, simple enough, unless you wanted all the thinking to be done for you..apparently you did...or you thought that I should magically determine each readers level of vocabulary and write to each person personally...especially you.. ( my Mum, no longer alive..would have said to you.."Oi..what did your last slave die of sunshine ?" ) I'm also aware that because I've been reading about this in at least 3 languages , even before the Covid 19 crisis hit in China..and I am living in a country , France where all descriptions are written "reversed" in comparison with English, and all chemical names and formula are also likewise "reversed ", and all descriptions of equipment and masks and medical procedures bears no relation at all to the same descriptions in English ..and as I already said in a previous post ..brand names ( the names on the bottles in your country, which I left 30 years ago) , that you want me to research for you , to save you looking at the backs of the bottles for the chemicals they have in them..are not the same brands, not the same bottles, how the hell would I know what the bottles that you have available are called..I can't..I don't.. So you'll have to do that bit for yourself. Also I'm aware ( acutely aware in fact ) that I may be, or may have been ( due to tiredness and stress etc ), making translation errors, procedural errors or even factual errors..and so I keep coming back to my posts and editing and re-editing them when I think I have not been clear enough or simple enough or correcting such mistakes as I become aware of..I'm trying as hard as I can via all the channels that I can to alert our health authorities here to the fact that the masks that they have and that they have distributed and have ordered and are manufacturing and are distributing to my wife and her colleagues are leaving them ( and their families ) all vulnerable to infection..I'm doing this knowing that If I get it..I'm ( due to pre existing medical conditions which I have mentioned, ) à due for a pine box..with all the disruption and emotional trauma that would bring to my family..plus I'd like to keep living a bit longer. And you are whining that it isn't in simple enough words for you.. Others have contacted me privately to say thanks for making the effort and taking the time to post..and to make masks..I didn't post to get praise, they know this ..But I thank them all the same..They know who they are..Thanks too Bert and Arven and sheilajeanne..Please forgive the errors..I was doing my best, in very difficult circumstances..You toxo are the first to bitch ( publicly or privately ) that it is too complex for you..and that I should make it all in simpler language...this despite the fact that I personally helped you with a design of your dog and advice about your laser, both of which took my time..and time is all any of us have ( not the first time that I've posted that "truism" here ).. I've never posted here to show off my work..My very first post was to ask for help..and Eric so very kindly helped me privately with a link to the engineers manual for my Juki..I have enjoyed reading so many posts by so many people here..I have always tried to help when I could , as you personally know. But..you think that my help is too complicated..even when I'm posting trying to help save lives, yours and others.. Well sunshine..You have shown me the error of my ways.. Time is all I have..it is all any of us have..and you have shown me that I have been wasting it posting publicly.. I may not have as much time left as I thought..certainly not to waste it on you..again.. So..this will be the last post from me here on this site on this or any other subject. The rest of you..stay safe : ) ..make masks..treat them..
  6. Read up on how the invisible formatting in word screws up copying and pasting into web pages.. Then again..life may be too short for that.. You can also make what is called a black cow with Guinness ..I used to have them when I was a child and we went over the river to go shopping in New Ross.. I'd sit and read comics ( from a fantastic shop that sold them and would let you swap them too ) whilst I drank / ate mine. :)
  7. Additional information currently being linked to by the BBC.. https://www.bbc.com/news/live/world-52087619 you may have to scroll to get to the item as the BBC page there is updated continuously..they are actually reporting about an item in the LA Times https://www.latimes.com/world-nation/story/2020-03-29/coronavirus-choir-outbreak Research https://www.nejm.org/doi/full/10.1056/NEJMc2004973?query=RP published on March 17 2021 shows proof that Covid 19 can be spread by "aerosol"..note that "aerosol"* in this instance is merely the technical word for "airborne" ( as in when someone sneezes or coughs that the droplets that they release can travel in the air, ( IMO further than the "social distancing" of 1metre recommended in France, or the 2 metres recommended in the UK and the USA ..I used to be able to cough and move a small piece of paper hanging on a thread at 3 to 4 metres distance from me , before my lungs got attacked by H5N1 a few years back, and subsequently pleurisy, I'd say a minimum of 5 metres should be observed for social distancing ) and "hang around".. Which is why everyone should be wearing masks ( treated as in my post above ) so as not to catch covid 19, if someone sneezes or coughs in their vicinity, and / or so as not to spread covid 19, if they are infected ( even asymptomatically ) if they sneeze or cough.. search for .. airspeed of a sneeze or a cough sneeze around 100 miles per hour ( 160kms per hour ) .."droplet" count..over 100 thousand per sneeze..so sneezing fit count ? cough around 50 miles per hour ( 80kms per hour ).."droplet" count ..close to 3 thousand per cough..so coughing fit count ? Read the airspeeds for each..and the number of "droplets" potentially each carrying large numbers of viruses that are expelled by a sneeze or a cough.. Sneezing or coughing into the crook of your elbow is not going keep all of that from flying through the air for further than 1 or 2 metres.. Wear masks, ( treated as per above ) make masks ( treated as per above )..donate masks..( treated as per above )..and show the receivers this page so that they know how to wash and retreat the washable ones. *Aerosol does not mean it is definitely all a plot and that someone has been spraying it around from a can.
  8. Had you looked around the forum a little before posting your self congratulatory piece. You'd have seen that people here ( and from all over the world, not just America ) have been producing masks for a month or so already.. We are donating all of ours..are you ? Please find in the link below..the thread already running here that you missed..Please read the thread from the beginning..and especially the linked research article dating from 2017.. re barriers against corona viruses by using saturated salt solutions on filter materials ..the link within that thread directs to the aforementioned article at nature.com. If you are donating your masks ?....thank you for your help :-)
  9. I've just heard about the "Battelle sterilisation method"..which consists of using Hydrogen Peroxide vapour under pressure to sterilise used masks so that "they can be reused up to 20 times"..Hydrogen Peroxide does indeed sterilise, I use it in a solution ( hand wash and equipment wash#, in the hand wash it is mixed in along with an 80% alcohol solution and a liquid soap surfactant and chlorhexidine and another combination of disinfectants*, available commercially and cheaply, proven to be 99.5% effective against bacteria and viruses including the corona virus family ) that I have made for my wife's "decontamination procedure" when she arrives home after her "rounds" of her patients.. It ..the Battelle sterilisation method ( Hydrogen Peroxide ) is a well known and very old method of sterilisation ( it is also what was used to "bleach" hair "blonde"..etc ) and is the active ingredient in "oxy action" washing powders and additives..But..it is very destructive to most fibres and threads if used in concentration..and can cause skin problems and lesions unless it is thoroughly rinsed off the items that it is applied to..Hospitals could use ( and already often do ) this simple, and extremely cheap chemical themselves..but they don't use it widely,mainly because of the destructive effects to items treated with it or in contact with it if it lingers. It will on brief contact "burn your skin" to a white colour by killing the skin cells.. It is not a "miracle method"..the reason that disposable masks cannot be reused many times after being treated with it are multi-fold.. Firstly 20 times is wildly optimistic..it is likely to destroy the mask "integrity" ( and hence any "protection"..and remember an N-95 doesn't actually block Covid 19 anyway ) with 5 or 6 re-uses.. Thus it gives a totally false sense of security..the mask is no more effective after treating with Hydrogen Peroxide than it was before being treated.. But it "saves money"..except it doesn't..because the process has to be paid for.. What it does do is provides a "stop gap" measure for the lack of masks..Don't need to worry about not having enough masks, if you can re-use the ones that you have, even if they can only be re-used in reality 5 or 6 times before they begin to break up.. Of course the real issue is that there is no point re-using a mask that is not effective at all against Covid 19 on it's first use ..and that is made no more effective when Hydrogen Peroxide is used to sterilise it..A non effective mask is sterile when it comes out of it's packet..re-sterilising it ( when it still lets through any Covid 19 virus that it is in contact with ) still makes it a "placebo" non effective mask..But it sounds "hi-tech"..and requires "a machine"..and someone will get rich supplying the machines..and so will others..meanwhile people will have been given false hope..and people will continue to die..when the mask treatment solution proven to be 100% effective against corona virus , and which requires no special machines, nothing more complex than saturated salt solution, either included in the filter layer during manufacture, or added to existing stocks of masks by spraying on their surface..is not used widely.. *Didecyldimethylammonium chloride at 1.8% and Benzalkonium chloride at 0.6%..base solution ..which is then further diluted by the addition of 3.5 litres of water at 20°C..( edited to add the further dilution step which I missed earlier )..Yes I know that both compounds have some "problems" and are not recommended in all disinfecting situations, but in these concentrations they are effective at 20°C ( room temp ) , are fast acting..and do work against Corona Viruses..and are easy to come by in concentrated form in almost any drugstore or supermarket in the washing products or detergent aisles..Brand names which contain them vary from country to country..so read the tiny print on the labels..Look them up individually on wikipedia for some of the brand names that contain one or both of them in your country.. Other compounds which work ( and may have better reputations re allergic reactions etc ) can be much harder to get hold of. Chlorhexidine is the active ingredient in many prescription ( and "off prescription" ) mouthwashes ..usually sold / packaged as pre diluted ( ready to use ) as a solution of strength 0.12%..which is fine . #The hand wash contains 80% alcohol***.. The textile and equipment wash contains no alcohol ..This allows for equipment including textiles textile masks etc, to be disinfected at 20°C by soaking for 15 minutes in the solution, or hand or machine washing at 20°C , or simple wiping down carefully in the case of cleaning and disinfecting of smooth non absorbent surfaces such as eye protective goggles or clear masks etc. ***If you make any of this..bear in mind that any wash ( or hand gel commonly called "hydrogel"..Purell ( spelling corrected ) is the name of the most widely known version in the USA ) that contains alcohol, is highly inflammable ) handle it and any alcohol carefully and away from flames and sources of ignition. All kinds of things can cause skin irritation..test any of the above ( or any combination of the above ) by rubbing a small amount on the inside of your wrist..and waiting 30 minutes to see if you have any irritation..irritation may develop later..you use any formula or substance mentioned in this post or any other entirely at at your own risk..There are no guarantees..read the science articles linked to..make up your own mind.. Stay safe..stay home..keep your distance..wash your hands frequently..Act as if you and everyone else is contagious ..protect yourselves..protect others..and if you can..make masks..with a filter pocket..wash the masks and and saturated salt solution treat them daily .. saturated salt solution to treat the filters , dispose of used filters daily.. Destroying the virus requires breaking or disrupting it's outer membrane, this is done by bringing it into contact with various chemicals..including ( but not limited to ) the ones which I have mentioned above..and soap ( strong soap not mild ) , Alcohol at over 70% ( not % like in Whiskey ), bleach in dilute form ( Don't use it "neat", use it well diluted as if you were washing salad from the garden, how much you dilute it depends on what strength it was when you began ), Hydrogen Peroxide etc..and salt ( NaCl, in either crystals or strong solution ) contact with salt makes the virus "explode"..kind of like how salt on a slug works..uses the same principle..
  10. Heh zuludog..from someone who was educated ( mostly ) towards be a microbiologist ( with leanings towards the veterinary research side )..and who switched "midstream" ( after doing the chemistry and the biology parts ) to professional artist, designer, sculptor..and who is also in an "at risk" group..especially as I have mentioned in an other thread my wife is a health care worker in the front line of contact daily with covid 19 infected people ( and who today did her 15kms of "rounds" on foot ( she normally does them on her mountain bike, but it was and still is blowing a bitterly cold storm, and she, being tiny and only 45kgs walks when it gets windy so as not to be blown all over the road even with the little traffic that is still moving as it is all going like a bat out of hell on the empty country and coastal roads here )..I'm staying "confined" except for food and diesel shopping..and making covid 19 protective masks until I run out of materials ( textile and elastics etc )..We have a "decontamination procedure" in place whenever she comes back to the house..She and her colleagues are frightened , but still working..health workers here have already been contaminated and died. We are atheists like yourself..added to which the outbreak in France is centered ( France's Covid outbreak ground zero ) on an evangelical church in the east of France whose "star" pastor held a service in February after the Italians and China etc had already been all over the international news..for thousands of his "followers" in a conference centre which lasted 48 hours , despite health service advice at the time to avoid close contact and especially large groups of people in close proximity.. The followers then all spread out and went home..to "all over the country" and "all over the world"..one of them was a nurse at a hospital in the east of France, where the deaths have been the highest, they now have traced her to having contaminated over 250 people..and Covid 19 is now ravaging France and all the countries that his followers went to when his service finished..he has since said "he knew about it, but thought it was not important" and that "he is now sorry, but that he feels that god has chosen him to lead prayers in this time"..That is so far ( and the numbers are rising ) 2000 dead in France alone, that can be traced back directly to this one "evangelical pastor's" meeting..he "passed the hat" ..got personally richer..( as they so often do ) and the "followers" went out, unaware, to spread the virus..to France and onwards to the world.. ps..for microbiologist reading.. https://www.nature.com/articles/srep39956 .I posted it in another thread re "making N95 masks " already.. 2017 research ..highly relevant , and an arm ( if used , and applied ) against the Covid 19 outbreak. To return to "keeping busy"..we in France are scheduled to have another 15 days of "lockdown" beginning/ continuing starting next Tuesday ( April 1st ..ironic ) ..and..if the PTB have any brains at all, they'll add on another 15 days at the end of that, and another 15 days at the end of that and so on until we are 6 to 8 weeks locked down in total so as the effects can begin to be judged ..and to give the health workers and supply lines chance to catch up..of course all bets are off if there is another outbreak or a second wave in China..Or if "someone" on the other side of the pond decides to get belligerent with China so as to distract from their own ineptitude re Covid 19..A war is the best "look squirrel" that there is.. Anyway..when I run out of mask materials..I'm going to be painting , drawing, and sculpting, and showing my son all the techniques and skills that I may very well not / never get the time or chance to do if I get infected..
  11. Just took a break to add.. Don't fret the needle size too much..When you look at the actual diameter of the hole made in any textile ( and textiles close up again around the hole unlike leather, which does close up again, but not nearly so much ) by that size of a fine needle, like a 12 or a 14 or a 16..it is huge compared to the size of the virus diameter ,each SARS-CoV-2 virion ( Covid 19 ) is approximately 50–200 nanometres in diameter..and the droplets containing them, expelled by someone infected when they sneeze or cough are > 5-10 μm in diameter...The viruses could set up a viral marching band a 100 viruses and more across and still march "side by side" through the hole left by a size 12 or 14 needle..What is fairly important is to match the thread size with the needle size ( there is a "thread to needle" size chart that wiz links to ..and whose URL I cannot remember ATM ...? ) even a needle up to a size 120 would be fine..providing that the thread is matched to it so as to "fill" the holes left by it as much as possible..the surface tension of the droplet ( sneezed or coughed droplets do not have much surface tension..less than a drop of water ) when it encounters a porous barrier, such a textile, and the surface texture and physical and chemical properties of the textile ,is more important..Droplets ( and hence the viruses ) last / "live"* longer on smooth surfaces such as plastic and stainless steel ( although less on copper and silver** and some other metals ) ..they "live" for less time on paper and most textiles. *"live"..There is "debate" about applying the term "live" to viruses.. ** Do not drink silver solution, anyone recommending it is completely wrong, ( and probably scamming you ) it is dangerous ( can kill, certainly will not cure or prevent Covid 19, nor will it protect against it..But it will make you look like a smurf..and probably a dead smurf. Oh..and the reason that hospitals prefer things made from cotton or polyester cotton blends is nothing to do with their efficacy against viral infections as such..it is that hospital laundries ( or their outside contractors ) are set up to wash at between 60°c and 90°c to prevent infection and or parasites lingering between washes..a lot of other fibre blends cannot support those temperatures ( some even melt ) so they prefer cotton or "polycotton" , so as to be able to use standard washing procedures , they are not set up to run "special temperature washes" for unknown blends of unknown man made fibres..If using the saturated salt barrier filter method ( as an inserted renewable polyester filter in a "pocket mask", washing at those temperatures is not required..But hospitals ( for the moment ) have more urgent things to do than to swap filters and to wash separately..Better that they treat ( with the saturated salt solution methods ) the disposable masks with the included filters that they have huge stocks of and which are in the pipeline.
  12. Here, the egotistical Parisians who fled Paris , ( bringing their virus with them to contaminate us and when they fall ill to then fill up our scarce intensive care unit beds in our under-ressourced local hospitals ) for a holiday in their second homes on the coast on the 1st day of lockdown ( and who are still arriving despite lockdown )..Just let their children run loose in the local supermarkets ( thereby making it impossible to keep a safe distance ) when they venture out for their food..Food which is ever more scarce, as supermarkets , and their supply lines, are not set up for a doubling of the "local" population outside of tourist season..I'll laugh ( if I and my family are still alive ) when the Parisians are gone.
  13. I would also suggest reading some of the more recent comments on Joanne L's page that I linked to above. In particular someone posting recently there references this link..I didn't mention it in my previous post here because it is somewhat complex unless one has a medical or scientific background. https://www.nature.com/articles/srep39956 Ferg ..Thankyou ..the article there from a research team looking into ( back in 2017 ) ( and having 100% success rate ) into antiviral treatments to N95 type masks ( which normally offer no protection at all to corona viruses due to the size of the gaps in the polypropylene non woven filter layer in them..they are a 3 layer sandwich ..outer layer..filter layer..inner layer )..It is obviously better if the filter layer can be treated with a "salt crystal barrier* before the N95 type mask are manufactured, however many hundreds of millions, if not billions of them have already been made..and the production lines on the machinery in place is set up to use the polypropylene untreated..But, I have found that the standard N95 type mask can be "retro-treated" ..I have some, as my wife is a health care worker in daily contact with potential Covid 19 infected, ( and some actually infected ), geriatric patients in their own homes and in care homes here. This involves simply making a saturated salt solution ( with a small amount of surfactant ....the ubiquitous liquid "dish soap" will do, at about 20ml per litre of saturated salt solution ) and spraying it lightly ( enough to wet it ) on the outer surface of the N95 mask..and then allow the mask to air dry before wearing. This is able to convert what was a basically useless mask , the N95 type, against the Covid 19 ( and other corona viruses ) into a highly protective mask ..there is of course still the ^problem of "the fit"..N95s fit badly at the sides, and thus expose the wearer to contamination that is not coming from the front..The mask type referred to here in France as FFP2 ( which is a mask made primarily from a laboratory filter paper type and is close fitting ( the kind of "beak mask" and it's variants ) ) gives better lateral protection..however even it would benefit from treating with the saturated salt solution..enough to coat it, but not to dissolve or weaken it. I've been treating her N95 masks just before she leaves the house to begin her rounds, and also each fresh mask as she needs to change them..Normally the recommendation for an N95 type is to change them every 3 to 4 hours ( even given that in their unprepared state they are ineffectual gainst corona viruses)..due to the shortage of all masks ( even for heath care personel outside of the intensive care units in the hospitals ), she , and her colleagues have been dealing with Covid 19 for the past month with no masks at all until 7 days ago when they were issued with N95 type..but only at the rate of 2 per day..( 12 hour non stop working day ..in close contact with patients )..We had already been making washable textile masks ( with a "pocket" for filter paper than can physically filter out the virus size particles ) since early March ( I'd , as I said above stopped all other production to work on them )..and she was aware that the N95 is more "for show" and reassuring the patient than for any actual prevention use...As many of her patients have dementia in various forms ( Alzheimer's is only one form ) many are not aware at all that there is a pandemic, nor what a pandemic is, many do not remember who they are. reassuring them is important..they do not get panicked by the sight of a health worker wearing an N95 or any FFP2, the face covering textile mask is another matter, particularly as all the textile suppliers here are closed down, or not delivering and travel is forbidden , and my textile stock ( which is fast running out ) is black, or fluorescent orange, fluorescent yellow or fluorescent green. When making any of our very rare excursions out for buying food or diesel etc, we have been wearing our production textile masks and washing them ( rotating 3 masks ..wear, wash , dry ) and then treating them with the salt saturated solution and a chlorhexidine biocide solution ( perfectly safe for skin contact, or to be breathed in, as is saturated salt solution, whether dried** or humid, and the two can be mixed ) * Doesn't need to be a solid barrier of crystals..just a saturated solution of salt impregnated will do..the crystals themselves are minute or microscopic.. **Because of the way that the saturated salt solution works in it's interaction with the virus, it is better if the solution has dried on the mask before the virus contacts it..it will still work if humid, but the effect is lessened..( IMO probably down to 70 to 80% effectiveness ) you'll understand why upon reading the research paper . Btw..if you are making washable masks, with, or without the "pockets" then polypropylene as the padding or filter will do fine..if they are for sterilising with heat ( as in hospital use ) then the pocket version is better, as whatever you use for a filter layer can be removed and replaced before the mask goes through the hot wash..if you use the salt barrier treatment make sure to re-do it before wearing the mask again..I find it easiest to supply masks in sets of 3 ( each with a colour code stripe*** ) so that the wearer ( do not wear someone else's mask ) is able to identify easily which mask is the next one in the sequence that is to be worn..orange striped mask today, ( "todays" mask when worn, goes into the wash and when it comes out gets retreated and put to dry ) yellow striped mask tomorrow, green striped mask the day after tomorrow..and repeat. *** if you are adding nose wires..the colour stripe can be used to contain the nose wire.. lastly..the kind of polypropylene that is used as filters in the N95 and as an additional filter in some of the FFP2 variants is everywhere and is really cheap , less than a dollar per yard..all you have to look for is "polypropylene non woven"..the "non woven" part is important as the spaces between the fibres are already smaller than in almost all woven type textiles.apart from some of the specialised types that cost a lot more, or are not suitable for washing or other types of sterilising. So..back to mask making..another batch to finish and treat before tomorrow ..I'll read through for typos just the once ( my system says every word is a typo ) Added..I'd be more convinced by the "Dr Kwong" at diymask.site ( in the post above mine ) if he didn't think ( against all the scientific evidence to date ) that N95 masks worked against Covid 19..and if he didn't refer to facebook so that the facebook page that you land on shows you advertising and the page owner gets paid per person landing who looks at the ads.. We are ( and have been now for nearly a month ) making masks at no charge at all and donating them to mediacl staff and other health workers, without being paid for any of our materials our time..that is all we are currently doing, as are many others, pros ( waves to Brian "RockyAussie" and hobbyists, here on this site and elsewhere around the world..and the mask version in the pattern on Joanne L's site has been endorsed by many French hospitals and other hospitals and medical staff around the world..They do not claim to have invented something that was invented by someone else and has existed since 2013, nor do they send one to a facebook page where you'll be shown ads, tracked by facebook, and they and facebook will get paid per ad shown to each and every visitor.
  14. Already discussed https://leatherworker.net/forum/topic/89282-making-n-95-type-masks-sharing-pattern-to-leather-workers/?tab=comments#comment-611118
  15. Possession of a "sap" or similar "scrote dissuader" ( this looks ever so much a very ingenious one ;) ) is an offence, IFAIR in the UK..plod may well take a dim view.
