Forma for The Soil Strad


Recommended Posts

The original neck of the Soil is preserved in the "museo del violino" here in Cremona and brings the autograph letter G on the remaining pegbox side.

According to Sacconi (page 126), this should indicate the form used to build that violin.

However even the Messiah brings the letter G written inside the pegbox but would seem built on the PG form.

This two forms are very similar and in my opinion the G is the "remake" of the worn PG, so maybe the letter inside the pegbox is not so representative of the form used and could be related to the neck pattern.

And so, G or PG? Difficult to be sure, although I am inclined more to the G.
The only photos and measurements that I know for the Soil can be found on the book "Antonio Stradivari - L'esposizione di Cremona del 1987"

and were taken (the measurements) by Bruce Carlson if I remember correctly, so maybe he could help.

I believe your first born male child is the customary offering... or is it spinning straw into gold?  Oh, well, never mind.

For Peter only

 

Mould thickness = minimum rib height - [(2x lining width) + (~ 2 x 2 mm for clearance between mould and lining)].

 

Say 30 mm - 2x8mm - 4mm = ~ 10 mm. 

 

So 12.7mm would work if you have less clearance between lining and mould and narrower linings.

 

But you knew that already.

One thing to remember if that a thicker mould is more difficult to remove from the garland if you are one of those folks who glues all the linings in before removing the garland.

That's why I asked for thickness, because it can't be calculated :)

It must be tested and from what I have read 13 mm is good to remove the mold, when both linings are glued.
