This photo shows the end result of this rough out stage.
I have developed a 2 1/2" diameter disk sander attachment which is used with a high speed drill to sand profiles. This is somewhat superior to using violin making hand planes because the figured maple has a tendency to chip out wood from the surface, under plane or scraper.
Again, working in low level (from the side) lighting, is important to check progress.
Here I am using the foam sanding block with various grades of sanding paper: # 100, # 150, # 220, then # 400, to refine the shape.

...I read some where that a ratio of {7 to 10} might be a good general guide to violin plates {front to back} by weight. This would be before varnish is applied. Thus a 90 gram back plate and a 63 gram top plate might be a good matching. {once completely finished and tuned.}
