Peter K-G Posted September 5, 2014 Report Posted September 5, 2014 I need to make a new mold for my Soil project. Anyone could share a full scale drawing? What is the optimal thickness for linings on both sides?
Addie Posted September 5, 2014 Report Posted September 5, 2014 Is that the "G"? I have full size drawings of several, including the G.
Michael_Molnar Posted September 5, 2014 Report Posted September 5, 2014 I think it's the "PG". I'll check later.
Berl Mendenhall Posted September 5, 2014 Report Posted September 5, 2014 I'll side with Addie, I believe it's G. I heard a Pearlman interview once and he said he liked it because it was just a little bit bigger than most violins. I could be wrong, that's just from memory. We all know how that goes.
Michael_Molnar Posted September 5, 2014 Report Posted September 5, 2014 According to Pollens it is a "G" form. See Stradivari p. 112.
Peter K-G Posted September 5, 2014 Author Report Posted September 5, 2014 So next would be to start negotiating with Addie to get the G mold drawings
Addie Posted September 5, 2014 Report Posted September 5, 2014 I believe your first born male child is the customary offering... or is it spinning straw into gold? Oh, well, never mind. G Mold Upper-A4.pdf G Mold Lower-A4.pdf
Davide Sora Posted September 5, 2014 Report Posted September 5, 2014 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.

Urban Luthier Posted September 5, 2014 Report Posted September 5, 2014 i believe the difference between the PG and G is the lower bout is a bit wider and a little longer

Davide Thanks Addie and Davide!
Peter K-G Posted September 5, 2014 Author Report Posted September 5, 2014 Really nice drawings Addie! (and sometimes my son would go for free he is 16)
Addie Posted September 5, 2014 Report Posted September 5, 2014 Peter, does your son do fences? I need about 300m put in.
Janito Posted September 5, 2014 Report Posted September 5, 2014 @ Addie I noticed you specify A4. Do these PDFs distort if they are printed in US Letter size?
Janito Posted September 5, 2014 Report Posted September 5, 2014 @ Addie I noticed you specify A4. Do these PDFs distort if they are printed in US Letter size? and the answer is Yes.
Urban Luthier Posted September 5, 2014 Report Posted September 5, 2014 make sure your printer is set to print at 100 percent
Janito Posted September 5, 2014 Report Posted September 5, 2014 make sure your printer is set to print at 100 percent Too true. Thanks!
Addie Posted September 5, 2014 Report Posted September 5, 2014 @ Addie I noticed you specify A4. Do these PDFs distort if they are printed in US Letter size? You probably want this one... G Mold US-Legal.pdf
Janito Posted September 5, 2014 Report Posted September 5, 2014 You probably want this one... Thank you.
David Hart Posted September 6, 2014 Report Posted September 6, 2014 make sure your printer is set to print at 100 percent Unless you're David Burgess.
Peter K-G Posted September 6, 2014 Author Report Posted September 6, 2014 Thanks! http://www.thestradsound.com/ongoing/makinganewmold-stradivarigforma Is 12 mm thick sufficient for setting linings on both sides?
Janito Posted September 6, 2014 Report Posted September 6, 2014 Is 12 mm thick sufficient for setting linings on both sides? You can work that one out with some simple Maff (translated as Maths).
Peter K-G Posted September 6, 2014 Author Report Posted September 6, 2014 On mold thickness http://www.maestronet.com/forum/index.php?/topic/236259-mold-wood-thickness/ For Janito only: The Maths 1/2" = 0,5 * 2,54 cm -> 12,7 mm
Janito Posted September 6, 2014 Report Posted September 6, 2014 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.
Peter K-G Posted September 6, 2014 Author Report Posted September 6, 2014 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.
