I haven't done much to the C bouts yet, I tend to put that off for a while since those are a bit awkward for me to carve into. But I'll bite the bullet and start working on them soon.

I started rough arching for the long arch. Cutting away the excess thickness from the neck and tail ends. I'm going to establish the long arch first before tackling the C bouts, I think they may be a little easier once the arch is more defined.

By the way, this plate holder started out as a copy of the one in the Stradivari museum in cremona but that one has straight sides and I found in the last build that straight sides get in the way. Other than that it seems to work ok as a plate holder.

Not much progress to report. Last night I started using cross arch templates, maybe a little too soon, I should do more rough arching first I think.

The build is semi-onhold temporarily as I have to do a kitchen remodel. Sad

But I'll try to get more done on the arching as time permits and post a picture...

After pouring epoxy countertops last night, I was able to spend a little time in the shop for some more arching. This is only my second build so I'm learning as I go. I got a bit ahead of the process and started trying to use templates too soon, should have done more rough arching first and will do so in the upper bout and C bout. The lower bout is so wide that it seems hard to get a smooth curve across the width of it. After more arching in upper and the C bouts then the pencil guage to draw iso lines will show where the curved arch needs more work.

I used the little toothed plane just to smooth out the gouge marks for a better look at the overall surface shape.

Here's an update after the weekend. There's still a lot of refinement to do but overall, I think it's turning out well.




And just for fun....

Finally I had some time to do a little work on the violin last night. During the initial shaping of the outline, I file the edges down at an angle to make sure they are not undercut. Now I need to square the edges and after that, do the purfling scoop.

This shows the angle




And here, using a small square sided plane to get the edges square.
Using a thin sheet of plywood to elevate the plate so the plane blade has better access to the edge.

I still need to refine the corner shapes also.

I have trouble with corner shape, this doesn't look quite right. After spending some time looking at le Messie corners, I think mine is not right in the upper bout, too much curved I think. I have three more chances to get it right and maybe I can still re-work this one slightly to make it better.

There's a little upturn right at the end, if I take that off it might look better. That will make it slightly narrower though and I was aiming for 7mm width and it's at 6.8mm.

A rough pencil sketch of purfling to get an idea of what it would look like finished.

Here's the inside surface with the scribed line from the ribs.

Looks like I cut into 2.5mm overhang a little too much in the upper bout.

I worked on the rest of the corners. I know I need to improve corner shapes so I'll work on doing better when I get to the top plate.

Here's a couple pics. And a short video marking out the fluting or whatever it's called.






Here's the video link

I spent some more time on the arching. Photos at an angle in front of my computer screen and the nearly horizontal stripes in the maple and some remaining gouge lines make the arch shape more visible. In these pics there is a flat stripe remaining down the long arch. I carve up to that and then round it over in the final finger plane smoothing.

The last picture shows contour lines. The contour lines highlight areas that still need some work.
