Introduction: Corkscrew DIY
I suddenly needed a Corkscrew and I realised I didn't have one.
I took a 10mm thick Threaded rod (9cm long), and a big wood screw (8cm long), weld both, removed the sharp point with a Dremel (cut off disc).
and here is the result !
(PS: as a temporary solution, I succeed to use the screw through the ring of a 10mm combination wrench, scewed it into the cork, and opened the bottle by grab the wrench...)
