I am inclined to take off more wood looking for more flex. But not surpassing "E" note. Thanks all for spread your knowledge and help me to think. Regards Tango

This is the first time i made the archings with CURTATE CYCLOID software and not by eye as I used

Hi I am thicknessing a violin back up to achieve a "F" or "F#" note when tapping the plate with knuckles. I just arrived at "F" but some zone is thick (low bout 3mm) and I don't feel enough elasticity. I guess that I must continue the thicknessing, in spite of go far from F note. The note is clear. The weight is 102 gr. Don´t know the pg of the wood (peso específico in spanish) Thinking that the central cross arch is a little low (14mm) I think it would be better to leave a little thick. But how much I asked to myself. So the question is. When to stop Thicknessing? Any opinion would be apreciated. Thanks in advance Tango

Hi Giovanni Thanks for your valuable reply. Problem with my pc delay my response. Question: You wrote "minimum width at the CC bouts is 135 mm", Is this a caliper measurement? Regards Tango

Hi all, thanks for responses. I remember you that 56,2 mm is the measure written in the Roger´s article. I am inclined for 50 mm. This seems to me more normal but I guess Guadagnini knew more about violin making than me. I am taking note of all details for decide some measurements as: stop and neck lenght, middle bout , ff holes spacing and others. I made two violas Amati model that sounded aceptable (sold) Regards Tango

Hi I am trying to change some measurements of my 40,3 cm viola model. The case is the distance between ff holes. I saw in the R. Hargrave Strad article of 1785 viola 56,2 mm between ff holes . Is that distance some exagerated? I want my minimun distante of C bouts a 134mm. https://www.roger-hargrave.de/PDF/Artikel/Strad/Artikel_1998_12_Guadagnini_1785_PDF.pdf Thanks for any coments

This is exactly the varnish I want to make. I could not to do yet

Thanks all for reply. Regards Tango

Hi What's your opinion about tamarind pegs?

Hi The violin owner is not my customer so I only saw and heard the violin and the complains of the violinist. Of course I didn´t make opinios about that because that isn´t my shop. From the outside I saw that the highest point of the bassbar were behind the bridge. So I thought that this may contributed to the lowering of the neck projection but main problem surely were the weak archings. It was a good opportunity to observe, ask and learn Thanks Davide and Natan for your valuable opinions. Regards

Thanks Bill and Louis. Today I tunned that violin and guess that archings are some weak . Something to take note: the bassbar have the tallest part behind the bridge spot. So this two things may contribute to lowering the neck I guess ¿Isn´t it?

Hi How much the neck fall down, measured at the end of the fingerboard, in a new in a violin, when strings are tuned for the first time? I guess in violins made by me, between 0,5 and 0,75 mm. Maybe 1 mm at most. A coleague changed the neck of his old instrument and fall down 2,5 mm (at the bridge). The fall seems to stop after a month. Is it common such fall or may be the archings are weack?

Thanks Davide, I will do so. The following step is to calculate fingerboard projection at the bridge paying attention to "C" minimun size and string angle.

Hi. I think so because most violins and violas have this relation (3:2) resulting comfortable for players. But now I have to apply a given string length (370mm) in a short model. Stop aproach close to low corners So I can reduce a little the lower bout enlarging the middle one, or enlarge the upper one reducing the low, or modify a little all avoiding bow strokes near the low corner.

Hi. thanks for replies. I will go for 370 neck lenght. So I will make a new form. How important is to make a 3.2 neck-stop relation ?
