Day 3

 Today's work was basically getting the transverse arches done, roughing out the whole plate, carving with thumb planes mostly.

Here is the progress so far :

 Parabolic arching : basically this method consists of choosing where the highest point of your arching is and your final hight. With a formula you can find the aimed radius to make your templates. The long arch is generally composed of two radius because the highest point is not in the middle.

 It's a really simple and effective method to obtain a nice looking arch, Rémi got this method from Jacky when he was a student at the CMB in Belgium.
