As I turn the UV on, I saw outside, and miraculously, it was a sunny day in the UK, so I put it sunbathing for a bit: Additionally, I will take this moment to talk a bit about safety in the workplace: Cheerios, Riccardo964

I hope to have this problem! Cheerios, Riccardo964

@violins88 : I guess your answer got corrupted - there's none. Best, Riccardo964

Aren't these lamps 'too much'? How frequent should the position should change with this power? Have you had any 'burnt wood' experience so far, like if you forgot it on and went doing something else? Cheers, Riccardo964

Thanks for the tips!! Will certainly do. I could by another 20W eventually, and put on the other side, I have plenty of space in there after all. Best, Riccardo964

Hello friends, I've been busy studying varnishing, and this rabbit hole has taken me deeper into understanding the process, eg, oil vs. spirit-based varnishes, and whatnot, and it's ended up with me building a UV chamber to accelerate the ambering process (one can't rely on UK's weather, ever). Here's some photos of the final product: The chamber 'working': And with the first build: There's plenty of space, I know... Perhaps it could have been built a little smaller, but I can always downsize it later, so that's not a big deal. Some notes worth mentioning: I'm testing whether the lamp should be horizontal or vertical - the insect killer I bought (365nm UV light, 20W, 2400V) allows both configurations, so it will be a matter of effectiveness. As you can see by the photos, the domestic aluminium foil that I used was purposedly 'messed up' - I read that it 'reflects' UV light in more directions than a plain surface - it made sense, so I 'messed it up good'. I have added a smal fan to circulate internal air, and I added an exit by the top - I'm covered for 'safety' (I guess). The internal temperature after 1 hour reached 25C (ambient was 21C) - I guess that's good. I will keep track of it as I leave items inside for more time, but I was shooting for 25C-30C. I know that this setup was to be used later on, however, for my 'cold garage', full of dust from woodworking, this "UV Chamber" is working for protecting dust from attaching into recently painted varnish altogether, and also it offers a ventilation mechanism. I know the drawbacks. That's it! Now I will do some pigment experiments! Cheerios, Riccardo964

Just posted to see this: 25 years later... Riccardo964

I believe this assessment is correct. $3k to $4k range sounds reasonable. Cheerios, Riccardo964

I believe that if you take a library of violin images, train it to recognise patterns, ie, Markneukirchen, Cremona, etc, it will help the 'guessing game' and maybe provide an interesting 'base of discussion' for an expert to confirm or refute its findings, which will then be retrofeedbacked into the learning machine so that next time it makes better predictions. That ongoing process might 'put experts' out of the picture, as there will be less experts working and more machine learning mechanisms executing. Imagine one day MaestroNet is plugged with such a mechanism (for free, of course, ahaha ) and whenever someone posts "Violin ID" here, it will spit out "More of the same" or "Markneukirchen 1892" or else. Best, Riccardo964

I have to agree - that is tough with only YouTube videos and MaestroNet to guide one's effort. Best, Riccardo964

I have to admit that I cried when I saw this image: But everything turned out ok, right? Great interview! Cheers, Riccardo964

The more I read about varnishing, the more I think that there are more than one way to skin a cat. Comparable to sharpening tools & techniques, to the point of being sacred if one doesn't follow a microstep. I've been reading a few posts here in MaestroNet and of course there's no definitive (and simple) guide/checklist to follow. But I shall persevere. Vincerò! Cheers, Riccardo964 PS: I will definitely have to build a UV chamber, impossible to have steady sun in the UK.

I did some tests, and I've found out that the brush quality has a determinant factor in this. I will look further on how to wipe it with a pad and do some tests on scraps - thanks for sharing this. Best, Riccardo964

I've decided to go with a 'base coat' of what I've cooked, and here's some 'results': It's not a bad yellow, after all - not the yellow-dog-piss I was mentioning earlier. I did a very thin coat, and I intend to do another one after it dries out. I left it on the sun (2h, UK sun, weak as they come) as well: And here's my scroll after the 1st coat: I'm happy with the progress, despite some hiccups along the way. Learning a lot, and improving (at least I feel like I'm improving). Lots to learn still! Best, Riccardo964 PS: I'm wanting to create a UV chamber, thinking about pros and cons for now.
