Hi, you should use a qev with check valve in it, like that:

Ho my god that is a peace of art! It realy seem to be a real flintlock, well done.

If it is for your son and i red you're concerned about the power of the gun, you could use a system wich can regulate the spring tension, like i've done in my hamer valve gun. That's work realy well.

Oui exactement du noir de fumé, apliqué à la bougie comme tu l'as indiqué.

jackssmirkingrevenge,
I used nitric acid, i've let it in the bath for 5min it's quick but the preparation is long, you have to put varnish and black of smoke and let it dry, then you can draw what you want.

Yeah for the girandony it's a very good idea, i will probably do that.

mark.f : hi thanks, it took me two afternoon to do the acid engraving and the oil blueing. As you can see that is not right symetric and perfectly smooth because that's my first atempt doing these proces, but that ad a steampunk finish.

I saw your gun on youtube , very nice. That's perhaps the last picture wich is too much "clear".

Thanks you all! Air_dannon , i will make one video when my pistol hammervalve will be finished!! Gun freak yes its a muzzleloader, the problem is with a loading system will be i will loose bb more quickly and the 0.28 are expensive! I saw your videos on youtube i like your hammer valve gun to. Lazyb...

Hy everyone, i'm from patator forum the french spudgun forum hope you remember me . I'm still making spudguns and i've managed to make one wich works great, many shots nice acuracy and great power (for airsoft). So its a hammer vavle gun, with a c02 fire extinguisher valve, 8mm hole, very effective....

Wooow nice gun !! I'm happy for you that it works so great, you spend a long time and it's not for nothing.
I love the 3 burst!!!!

Ok thanks, i'm pipefitter and your VERA is a real job!!. If you need a worker i'm here!!!

Mig welding its not the strongest welding but with a fat pipe like that you need to be fast , no need to change your stick.....

Wow great beast .......... I don't know what to say it's so incredible

I would like to ask you something about your welding and the pipe .

So what is the pipe shedule? And what kind of welding have you used? TIG or high pressure stick welding?
So thanks if you have few second to reply.

BTB , haha perhaps its because i play too much fps. And i shot fast to show it could be presurised fast, wit...
