Haha, well I really couldn't face making a Messie form...there must be thousands. 

So I made a cross breed template and form, length of Messie with girth of Viotti. 

Think I'll name her 'Motti'.  :D 

 

 
 
So you have hybridized form PG with form G.
Me too, one of my preferred and most successful form.
Fortunately, the Cremonese form and method allows a lot of freedom of action, so I'm sure we can avoid making violins too similar...... <_< :)

Addie,

I have a honey do for you. :wub:

 

Would you please put  both of  the blocks on one side of the Forma P?

Nope. I'm trying to record the forms as accurately as possible. That means the existing corners are in their intended places. Anything else would be an interpretation, which is not my purpose.

But maybe look for a PM in a few days. ;)

I'm currently able to share the SL 1691.  Please note the lower bout width.  With the other measurements from the English ed. of Sacconi, only 194mm worked for the lower bouts, not the 195.5.  194mm is the width published in the Italian edition.  The Radii are my direct measurements. 

 

Also noteworthy: if you simply scaled the G on the horizontal axis, you would not get the SL.  The curves of the upper and lower bouts are tighter (rounder), and the block corners further out (wider) on the SL, compared with a squashed G.

Because of the Musée de la Musique cello form, it's going to be a LARGE format book.  :lol:

And would You share with us Your drawings of these forms? :wub:   (I think that there are forms of small violoncello, some viola da gamba, cornerless violin, viola d´amore and guitar)

Where did you get the measurements for the form SL?

Those that I have are different.

 

Pollens :   348   - 154   -  99    - 193

Denis   :   349.2 - 154.4 - 99.2 - 193.5

Sacconi :  350   -  153   -  100  - 194    (italian edition)

The English edition of Sacconi has, page 195, 350mm, 195.5mm, 154.5mm, 100mm.

Using 350mm and 100mm, I got UB 154.5, but LB 194 from the image I am using.

Which set of measurements do you prefer? If Pollens or Denis, can you PM me the full set of measurements for all forms?

It seems that the various editions of the Sacconi do it on purpose to change the numbers to create havoc, as if were not enough the inaccuracies of the original <_<

 

However, I think that the dimensions of your drawing are fine : with four sets of different measures, I would not know which one to choose, without going back to measure the original form....... :rolleyes:

 

Don't you have books of Pollens and Denis?

Addie, Thanks for the drawings.  I made my P form based on Denis' geometry.  The corners were a real head scratcher for me.  What I settled on, based on your drawings, falls between the P and G form corners.  I'm ok with that, and I feel better about it after comparing to your drawings.  Now if only my blocks were a good match to my template. :unsure:
