"I was thinking I would have to temporarily glue some wood to the side and square it to fingerboard area." Whatever it takes.. squared up is good.

The Biddulph 1998 2-vol set on del Gesú has a lot to ponder besides all the detailed measurements, full size photos and outline. If you want a reference seek out the book.

The Peter Biddulph book:, Giuseppe Guarneri del Gesu, London, 1998, includes the Il Cannone full size photos & specs. Maybe your local library can get it on inter-library loan if you do not have access...

Doesn’t David Bromberg specialize in American made, he is on the east coast as well... https://www.davidbrombergfineviolins.com/

Has Nathaniel Rowan name been mentioned yet...he has made some custom fiddles. If you don't see a can of spray paint at the hardware store you like maybe N.R. will share some ideas with you. (photo credit: Jack Magee)

As suggested above, glue on some scrap pine or some such— and then square it up:

Ha ha— Never seen it done this way before—like they did not quite have it figured out or 'artistic’ license (?) A real homemader...

A good starting point for your analysis... If you have access to a local library, you may find a interesting and insightful read in a back issue of The Stad Magazine, March 2006, "Trace Elements" by Joe Grubaugh & Sigrun Seifert pp. 42-48, with special attention to pg 45.

Personally if you are satisfied with the sound, I would not worry about it. The only concern cleaning with a rag to not get snagged and inflict any damage. Typically in new construction we lower that leading edge of the wing during the carving ( à la Stradavari) so as to not have that scenerio present itself. ref: Secrets of Stradivari - S. F. Sacconi

Beautiful.

There is no advantage being a self taught maker/repairer— go to a violin making school and get the proper training. Think of it as kindergarten with papers. Go from there.

Nice plaid

Hmmm... Any violin making book will contain information on peg whole placement, I would suggest studying up on the entire concept. http://www.weisshaarrepairbook.com/overview/ https://www.cremonatools.com/the-secrets-of-stradivari-s-f-sacconi.html
