Works that I have been ordered. Based on drawings, existing parts, client imagination…

Mechanical engineers say : 80% of material failure are due to fatigue. What is fatigue? When a mechanical part is subjected to repeated load below ultimate strength but above fatigue limit. In other words : pull the handle once, no problem; pull a thousand times it breaks. That’s what occurred to iron casted handle. The upper ring which forms the pivot is split into two. I will cast a new handle, using the broken one as pattern but with a rebuilt ring carved in the mold.

There is less and less blanks for old keys. When you can’t find one, the best way remains to cast it :

Based on a Sketchup file I order 3D printed patterns of buildings designed by Guillaume. Then, it’s a standard sand molding process.
