@@-DIEU-TE-CHERCHE-9923 Bonne question, point que je n'avais pas vérifié. Le poids est de 1,927 KG (environ 2kg en fait car j'utilise 2 petits capodastres pour maintenir les cordes quand je la replie)
I bought a combo head and bridge : www.amazon.fr/gp/product/B07G2TK876 The quality is good I still use this guitar regularly (especially now, as I'm on holiday), and everything still works perfectly; strangely enough, the guitar goes out of tune very very little when I fold / defold it.
Very interesting project and nice self explanatory video! Do you think bolts and threaded inserts (instead of screws) would be suitable for the headpiece/locknut? I've seen this design on Strobel Rambler detachable neck travel guitar, but it was made in two-piece locking nut with one thumb wheel, which they call StringKeeper. What about use of headless tremolo? It seems it will help to detach neck without detuning, just "dive bomb" and fix whammy bar in lowest position to release strings tension.
Concerning the use of bolts and threaded inserts, I must confess... I've no idea. Concernign the use of a tremolo, I had on mind but I've been afraid to use one because I wanted to tune the strings on the body and not on the head. Strangely, the tension is not so hard.
