De retour ici pour vous faire part de mes avancées :

Voilà la nouvelle fixation du canon externe :
Image

C'est un manchon en laiton de 20x27 diamètre 25mm.
Elle a été réalisé à partir d'un réduction 3/4''x1'' m/m.


Image

Le manchon 3/4" Ø25mm a été percé et fileté en M3.

Les trois cylindres en cuivre avec un méplat sur le haut et taraudé en M3 servent au guidage du canon interne à l'intérieur du canon externe.
Le méplat servira à laisser passé les fils pour le cinémomètre.


Le vérin avec le support du cache de la pseudo culasse :
Image

Une fois démontée :
Image

La "tige" du piston est un rond en aluminium de Ø6mm, dessus il y a deux bagues en cuivre usinéeset collés, et pour terminer un filetage en M6.
Les deux "pattes" en inox sont deux pattes de mise à la masse qui vont normalement sur des brides en inox sont des lignes de tuyauteries.

Image

Image

Le système, de vérin vient d'être mit en place, pour le moment, ça tient avec du scotch d'électricien, mais ce n'est qu'une question de temps.

J'ai enfin pu terminer le talon de crosse, j'ai quelques retouches peinture à refaire dessus.

Thanks :D.

At the moment I'm looking for an ergonomic relaxation.
  But no idea comes to me.

It shall be composed of the trigger, a micro switch and a spring recalls.

You do not have an idea JSR: D?

Absolutely beautiful, mate. I wish I had the materials and the tools. I'm aspiring to this level of craftsman ship.

*fwip fwip fwip*

My only complaint about this is the tiny calibre in relation to the massive rifle.

I would have made it at least 8mm.

The advantage of Ø6mm is that you can put a Hicap Feeder 300rounds.

Fair enough... but it's like a Barrett chambered in 22 rimfire :)

... and a big calibre rifle in full auto, who would be crazy enough to think of such a thing?

The Japanese of course :D

Actually, JSR, the 6mm is a really good idea.
Not only does it allow for the HiCap magazines, as he pointed out, it allows for a wide range of projectile weights in easily obtained amounts.
There are BB's that weigh only .12 grams, all the way to somewhere around .40 gram steel BB's.
This allows for FPS testing, accuracy testing, and also allows him to play airsoft if he so wishes.
6mm is a pretty versatile and available diameter.

Hi everyone :D!

I come to you, I've not forgotten. I just penned an exposure time since that day...

A bit of news now.

I'll redo the whole entire carcass was considered too heavy and I have some facts above.

Return / advancement of the cylinder head :

I would suggest less length and diameter for the reload bolt system, that's awful a lot of space just to move a bolt. You would save a lot air (more power) and faster response on the bolt movement.
