Nice!!!

All you have to do now is to open a thread in the pneumatic cannon showcase section, this definitely deserves its own place. :)

Is there a video of it firing ammo at semi-auto? And the muzzle "blast" sounds weird... I was kind expecting a BANG :lol:

no video in semi-auto yet, i'm having trouble with the return of the DCV's rod, and i'm waiting for the o-rings to wear off a littlebit, hoping that the rod will move much smoother :roll:
the weird sound is from the exhaust of the QEV, because i forced it to exit through 2 small holes (the original project made it a little hard to keep your eyes open when firing because of the exhaust, and i redirectioned it down - the grey pvc pipe )

Bueno, ya te pase los datos por MP ese rifle ya quedo hace tiempo atrás y construí algunos mejores, actualmente no tengo ninguno montado pero estoy trabajando a largo plazo en uno que va a ser muuuy bueno con cañon de 4.5 y similar a un sniper con cerrojo, con un mecanismo que ya teste en otro modelo.

Con solo accionar el cerrojo atras y alante carga el pellet, abre y cierra el aire a la presion deseada y vuelve el slide valve a su posicion cerrada, sin duda el slide valve es lo mejor como disparador, agrande el agujero de salida y gane mucha potencia comparado con el disparador tipo pistola que salen en las fotos de mi post.
Con solo mover el cerrojo ya queda listo para disparar.

También minimice el aire muerto al maximo y unas cosas mas, pondré fotos cuando lo acabe.

Un saludo maestro jackssmirkingrevenge

hy there, sorry for the long time since my last post, but i've been busy at work, and with my new airgun project, it's not done yet, i still have some work to do, but anyway here's a picture.

all i have to say is that it's the same principle as my last airgun (wich by the way I broke it to pieces because it blew my o-sealings aftel a duzin shots) but a completely new design, much more powerfull, more compact.... hope you like it.

indeed it needs a lot more sanding.I was thinking I could galvanize the metal parts to prevent rust. I just need to find some time to finish it.

This airgun works very well at 40 bar, haven't tested it over 50 though.
Finland66 - why so much pressure ? what will you fire with it ?

Don't go for acrylic. use knife and alot of sandpaper, sand it smooth to 2500 grit and then coat in few layers of oil. What wood is that?
