Re: [Vo]:Masks
Well this is Shakespearean, Tempest in a Teapot, Much Ado About Nothing, but not dead wrong. What they didn't tell you about using human hair as crosshairs in optical instruments is that not only is it too coarse, it suffers from sag in high humidity environments. No doubt the gubmint during the war was hoping if the hair hadn't suffered the usual abuse, it might work. I can only think that they tried it but it didn't work. Still Babnik was nice to volunteer her remarkable hair. Nearly all military optical instruments, binoculars, gunsights, battery commanders telescopes and anti-aircraft fire control optics use etched glass reticles often with altitude and azimuth markings. Those that don't use the glass reticles, use spider web which stays taught in a wide variety of environments. I should know, I worked in my father's shop during the 50s where he had a contract with the army to fix all of their severely abused optical stuff, most of which dated from WWII.

How do I know about this? My father was head of the instrument repair division at Camp San Luis Obispo during WWII. Among other things his subordinates had to tend terrariums full of black widows to harvest the web for crosshairs. Kind of a creepy job, no? Yeah, I know, far off-topic. and dead wrong. https://en.wikipedia.org/wiki/Mary_Babnik_Brown
Re: [Vo]:Masks
In Atlanta, a large group of people organized over the weekend. They are sewing mask covers. Not the masks themselves, but covers needed to protect hospital grade masks so that the masks can be re-used. Normally, they are only used once, but hospitals are running out. All over the country, researchers and doctors are finding ways to clean and reuse the masks. So, they plan to cover the outside with cloth covers, and then sterilize the masks. See: https://www.ajc.com/news/mask-sewing-network-built-metro-atlanta-through-social-media/IkmkKifwcPVt7QhNdNQsIL/ Cloth masks made of gauze and cotton are washable. They are much better than nothing, according to Japanese health officials. The Japanese government is distributing one to every citizen. My wife has been making them with a sewing machine. Unfortunately, she ran out of elastic band. There is none left at Walmart. I went on Amazon and found out that all elastic band is made in China. An inset photo from one maker shows a woman wearing a mask. The vendor wrote this plaintive message: "Attention please: We will send it 3-5 days after you complete your order. But now is a special period, there will be a delay in logistics, and the expected delivery time is 20-30 days. If you cannot receive this delivery time, please do not place an order. Thanks for understanding. Pray for the great American people to get through this crisis as soon as possible." This seems emblematic of the whole situation.

Re: [Vo]:Masks
I think that's great that these women are volunteering to make these masks. Washable is better. We have really become too much the disposable culture.

I have started to work with some local ladies to make masks. They are inspired by the ones on MASH. They consist of 5 layers of cotton in a square that ties to around your face. No claim of efficacy is made. They are washable. I will have some prototypes to show soon. No money is being made and they are doing this at home and at cost. I am dong this at a lose as I am trying to start some others up soon. Frank Z
Re: [Vo]:Masks
Simple masks are highly efficient if 100% of the population are wearing them, as in Japan with almost no infections. They prevent drops from spreading! But they do not fully protect you if you get a drop! Especially the eyes are a weak point! Further: If you are out, never touch your face before completing 30 seconds hand washing! J.W.
