“How the frames are finished.” Discover lesson 4 of the master Sandro Gonnella

lesson N°4

Filing and sanding

Once cut by the pantograph, the frame needs to be finished with extreme care. With the use of a file, Sandro removes any slight excess of acetate. It is a particularly delicate task: the excess material is only a few millimetres in size. One must be very careful not to cut into the acetate. For this reason, only the skilled hands of a master know the right moves. A little secret to begin following in his footsteps? In order not to damage the surface of the frame, Sandro also uses a piece of fine sandpaper. It is also crucial to proceed by small steps and never try to arrive too quickly at the final result.

A comfortable nose fit

Again using a file, Sandro finishes the angle of the nose of the glasses to eliminate any sharp edges. This is the most critical point for the comfort of the end customer, so it is good idea to dedicate a lot of time to this task.

One must be careful not to overdo it with the filing. To check your work, it is a good idea to try and retry the frame on the customer during the entire phase.

The tumbling

In the tumbling phase, all the sharp corners on the frame will be eliminated, thereby creating the classical soft and shiny look across the whole surface. Only with this technique, using the rolling friction of wood particles and abrasive paste, can we obtain a pair of glasses with perfectly rounded corners and is thus comfortable to wear. Since it is a standard process which requires no particular manual contribution, it is often conducted by outside technicians.
