Back to the viola making! Some photos of how far I got last week, enjoy!

 As you can see on this photo, I did the fluting (up to 0,5 mm over the final thickness) and quiet a lot of the arching before to cut the purfling channel. I really enjoyed to do it this way, it just feels more natural to carve arching and fluting together, as it is one full shape.
 Same for the back!
 The purfling channel has to be marked one blade at the time because of the fluting being there already. This was very new to me, and certainly not easy compared to last years method on a flat platform.
 The channel is done on front and back.
 The purfling is glued! This is a detail of C bout with top and bottom corners.
 Now is the time to finish the fluting to its final depth and up to the edge (as I left a small margin when doing the pre-fluting). On this photo, you can see how the fluting continues on the button.
 A detail of a top corner on the back, with the finished fluting.
 The arching is now completed using the thumb planes and scrapers.
 When scraping the archings, I use a straight edge and shadow to look for any bumps or undesirable flat areas.
 The back arching is finished and cleaned.
 The front arching is almost done, the next step is to make the f-hole template, mark the f-holes on the front and carve the f-hole fluting.
 Hollowing of the back with the gouge first.
 Then with the thumb planes. If you click on this photo, you can see more clearly the marks of the toothed blade I used to plane the flamed maple.
 Thiknessing the back.
The f-holes are marked on the front.

Some photos of the finished ribsructure.

 During the break last week, I made the mould and the ribstructure for the Viotti violin.
 Some photos of the ribs.
 Because this is my 6th ribstructure since the beginning of the course, I tryed this time to use quiet a lot of time to improve the precision and get good and even curves. I gave a particular attention to the corner shapes as they will determine the final outline of my violin.
 This is a detail of the left bottom corner. You can clearly see how the lining are inserted in the corner bloc coming from the C bout.
 This is the left top corner.
Another photo of the top corner to show the joint between C rib and top rib.
 This are the jointed plates with the outline drawn using the finished ribstructure and a 2,5 mm washer.
