ENGLISH TRANSLATION of the written notes in the video, in order of appearance :

00:04 - Bending the C ribs

00:10 - Estimate the temperature of the bending iron observing the behavior of water droplets, which will not have to evaporate staying steady on the iron but must bounce off very quickly

00:25 - Not yet at the right temperature

00:35 - OK

00:48 - From ribs previously prepared with 1.1 / 1.2 mm thickness and height of 35 mm, get two pieces about 15 cm long, taking care of the orientation of the flames in relation to the back plate

01:16 - Wet the rib with a damp sponge

01:34 - Use a copper or steel sheet to support the rib, backed with a wet leather strip to protect the fingers from the heat

03:12 - It's also possible to use special wooden jigs to help stabilize the tighter curves and to maintain a decent symmetry between the two C ribs

05:00 - Mark the position of the end of the blocks in order to have useful references during the refinement of the curves

05:16 - Heat the inner part of the C to obtain a slight convexity towards the outside, and not vice versa.

06:46 - Refine the curves leaning briefly on the bending iron at precise points, to obtain an adaptation to the form shape without excessive strains
