Me too. I played for a few years without a chinrest thinking that it would improve posture and control because you cannot grip and you have to be sensitive to the balance of the violin. It worked! But I went back to a chinrest to avoid damage to the varnish and I couldn't be bothered with the chamois leather/cloth rigmarole.

You're right but I have only had a problem with misting of my glasses when air was leaking between the mask and my face. Maybe the reason is that I wear high spec. prescription glasses and I suspect that anti-fog is part of that.

Quite so, but they are good for protecting the wearer . I have used them in my workshop for a long time now and they are much better than all the other breathing protection I have tried

Why don't you buy your own?

I use the 3M FFP3 masds which have a little plastic valve jobby in front for the exhalation. The cover for that seems designed to direct vapour down and away.

If the problem is caused by air leaking between your face and the mask it's not doing a very good job on dust protection.

Up to a certain level, but classical guitar can get really hard.

You can do vibrato along the string, which goes above and below the note, instead of across the string which only goes above the note.

I'm married to one. They are probably fighting over how you shape a reed, hence the knife.

The enormous cast steel gerberettes in the Centre Pompidou in Paris were heated treated after Krupp did not follow the specification based on the British code developed out of work for the North Sea oil platforms.

Soap and water is supposed to be the best thing for hands. I would simply rub the the violin with soapy hands for 20 seconds.

Your screws are possibly too small for this but if you grip the threads in a drill you can spin the screw and file a tiny bit off the underside of the countersink.

Isn't it called soldiering or clocking? It's used in fine woodworking. I was once in the washroom at work and noticed that the person fixing a wood duct cover was soldiering the screws. I complimented him on this and said how good it looked. He replied saying that he liked it to look good but the main benefit was that he could tell if someone else had been fiddling around with what was behind the duct.

As a slight digression I would suggest that intonation is more of an issue in recordings than it is in live performance which is a more complete experience, and where an error is gone in a second, compared with a recording where it is there for ever to bother you when you listen to it.

I broke my left collar bone when I was 14, also on a bike. It now rather protudes and, as I discovered, makes a perfect ledge for supporting the end of my violin
