I recommend you to make madder pigment yourself at home. It is simple and you know what you have because the true alizarin does not blanch. I make pigments using madder roots and chips of fernambuk. I can send you a sample of my pigment.

Awesome pigment factory you got there!

I like it and when I have more time I will do this myself - hope I can consult you when I start.

I've never seen commercial madder fading to this. Has it been deliberately exposed to strong sunlight for long periods?

I've a couple of instruments that I wouldn't mind fading!

Thanks!

I have looked through my notes/documentation and it seems that I used also tube paint, besides Kremer madder pigments. This was my first own varnish making and I also think I had to sand/polish between layers. I think I might have sanded away the Kremer pigments and left the tube paint "madder", which  has faded.  i.e. - Not artist grade tube paint.

Here you are, Peter. Remember - PH of water is very important for good colour. I used water from Polish mountain spring water without chemical as is in my town Poznan. Good luck!

Thank you Szymon!

This is great, because I have varnish in different darkness grade for different wood/grounding. It fits perfectly with my philosophy of varnish system - no nasty chemicals and knowing everything that is put on my instruments. 

I also happen to have a small espresso machine that I don't use so it will be fun to try this (once I get some time to do it)

Fjodor gave me some madder pigments that seems good so I have a reference how it should be.

Of course I also need to get some roots and pernambuco

Pernambuco I have from the violinbow maker, and roots from Kremer http://www.kremer-pigmente.com/en/dyes-und-vegetable-color-paints/natural-organic-dyes-und-vegetable-color-paints/580/madder-roots-pieces
I can send to you pernambuko. Remember - the roots have to be thoroughly milled, they are very hard. Coffee grinder is also useful.

As a gift for the Christmas, I gave the last violin I made to the music school in my hometown, so that the school would lend it to talented students. This is a sample of sound - a mobile recording

And this is the ceremony of giving my instrument during the concert

That's so nice of you! And sounds like a nice violin too!  :)

Thank you Szymon,

That is the nicest looking Christmas tree I have ever seen!

Christmas is about giving, so what would be better than to pick your favorite Christmas present from the tree :)

I have also given away violins it's nice. The best part is that they can't believe it's true, kind of a shock - You are really giving this to me :o

Thank you very much for these words. Indeed, giving is greater pleasure than getting.

This is results of body modes of this instrument. I made it according Patrick Kreit idea and Nigel Harris also.

I just listened to to the sound clip/video and it think it's a robust violin with a clear voice without no harshness. Congrats for another successful one.

You inspired me to take a day off tomorrow so I can finish my Christmas violin :)

Peter - very good preparation for Christmas Eve supper !!!
I glued the back plate and ribs during free moment helping my wife in the kitchen. Peter, how are you doing such beautiful deep flame? Beautiful neck! Beautiful colour and violin. Give us a sound sample in the new year.

Clever linings.

The neck wood has deep flames in it self so I just enhanced them with linseed oil and a little color.

Merry Christmas - Timing is everything Ham and Violin ready

I have been secretly copying Fjodor's latest violin and it looks like I got it about right. While waiting for the fittings and strings to arrive I have tracked the modes as the violin gain weight after varnishing. With a chinrest stable at 356 g. It's Plowden like with a strong B1- and less strong B1+

  A0 B1- B1+ B1-/B1+ Humidity
349 273 465 555 90 20 %
356 270 455 540 85 20 %

predicted values:

400 270 440 520 80 40 %

That's sneaky :)

Just kidding... I'm an a alphabet when it comes to signature modes and stuff. It will be interesting to see how they compare soundwise.

Exciting to play the first notes soon! 

Merry Christmas! 

Let's see 

predicted (with chinrest)

  270 440 520 80 40 %

actual (today after playing):

  268 448 526 78 25-30 %

 

Hope you get a surprise when you play it :)

I would really like to play some of LK's newest too, if he still have them

ps.

The ham was superb and Santa has been generous, so now we just wait for days to get longer again

Played it for 6 days now and it's lovely, smooth and delicious like chocolate and easy to play (like yours Fjodor). But it has more carrying power than I expected as the back wood was really low performance. High dens high performance top wood (Finnish)

It wouldn't be complete without a spectrum, compared to the last one ;)

Made this one different and it shows in the spectrum (even if they are not too reliable)

Bravo Peter, excellent parameters, very similar results! I can't do it.

I never measured the density of wood before work. What is the best top and back density ?

I have a maples  from the Carpathians -  for 4 instruments - and this wood gives me a weight of about 111 grams / 355 Hz averaged values for 1,05 stifness.

It is not possible to achieve precise parameters/results without the tables in Patrick's book. Everything starts from arch/volume/tuning

I measure wood and everything very precisely with some Excel  spreadsheets that I have made

Here is an example of measuring this violin's (second top, density ~0,49), the first one was bad

http://www.thestradsound.com/ongoing?offset=20

I can share the wood measuring Excel but not the tables as they are under Copyright

I have used various densities with the same modes/weight 

For ex. this one 0,49 g/cm3 is +/- 70 g, 350 Hz, a previous top with 0,40 g/cm3 has exactly the same parameters.

=> 2018

Grazie mille e buon anno!!! - as Stradivari used to say. :)

If you visited Poland in 2018, we invite you to Poznań. It would be nice to meet and talk about our passion.
