A folding butt carbine

Hola:

Para actuar, el "set screw" requiere un canal en el tornillo pèdrero (flint screw), que no se observa en la llave (lock) del post numero 20. No sé si el arma de Fernando la tiene....

Afeectuosamente. Fernando K

Hola Fernando,
I am not sure if it has to be always as you say. If there is a channel, you have to insert the setscrew always in the same position, which is not so viable, once the flints don't always have the same thickness, thus requiring different settings.

Hola, Fernando

No estoy de acuerdo contigo. El tornillo pedrero (flint screw) queda en la misma posición, haciendo presión sobre la mandíbula superior, cualquiera sea la medida de la piedra (flint), y en consecuencia, el agujero roscado pàra el "set screw" debería quedar enfrentado al canal (channel) del tornillo pedrero (flint screw)

Afectuosamente, y pese a las dificultades de la traducción, Fernando K

Hello, Fernando

I disagree with you. The screw scree (flint screw) is in the same position, putting pressure on the upper jaw, whatever the extent of the stone (flint), and therefore the threaded hole for the "set screw" should be facing the channel (channel) pedrero screw (flint screw)

Affectionately, and despite the difficulties of translation, Fernando K

Hola:

Ahora que estoy revisando todo, veo que en el arma del post numero 13, con el tornillo pedrero (flint screw) fuera de la mandibula superior, se vé claramente el canal (channel). La función del "set screw", sería la de mantener indisolublemente unidos el tornillo pedrero (flint screw) a la mandibula superior, cualquiera sean las vueltas que se de a aquel.

Afectuosamente. Fernando

Hello:

Now I'm reviewing everything, I see the weapon of post number 13, with screw scree (flint screw) outside the upper jaw, it is clear the channel (channel). The function of the "set screw", would be to keep the screw pedrero inextricably linked (flint screw) to the upper jaw, whatever turns you on to that.

Affectionately. Fernando

Caramba Fernando, ahora te entiendo .
Now i get it
I realized the set(screw) was in a lower position, in order to lock the flint screw thread, with the purpose to prevent it to get loose and allow the flint to fall off.
Now i see that the (set)screw is in a higher position and penetrates into the flint screw 'neck', in a way that the this may rotate but doesn't fall off the jaw. I guess the reason why this is a (set)screw and not a fix pin is that, in this case, you may loosen the (set) screw and dismount the flint screw for maintainance or replacement, when its thread is worn.
I hope this is understandable ... both post text and attached drawing .
