Hammer valve endeavour

[Hawkeye]

A short drill bit extender makes a good inline hammer. I have found that it's a slide fit in the smaller diameter copper.

Ah I also forgot to mention that I made a striker, it's just a 1/4" bolt with two washers that fit perfect in the pipe and a nylon spacer in between them that has two holes in opposite sides to hold two smaller bolts that are used to cock it. I appreciate the suggestion though. If I have one in my garage I'll check it out.

Success!

Awesome. Not a huge pressure drop either, so that's not too bad.

[Gun Freak]

Yeah, it was only 10 psi per shot. And it let out a nice amount of air at only 250 psi.

The first test, I shot it and looked at the push button, and it had indentations from the screw So the next shots I put paper towel in between and it was fine. I could easily make a new button if I needed to.

So I'm pretty happy it works well I need to make a proper hammer now...

[warhead052]

Can you post a picture of the hammer you have now?

[Gun Freak]

Sure.

It's gonna be replaced by a hex head screw with rubber pad on the head to protect the button.

I just found some old parts yesterday, and made my own. At only 100 PSI, I would be able to shoot an airsoft BB more that 500 FPS, and what's great is that it can be rearranged to be a semi automatic valve too!!

[Gun Freak]

Cool, but airsoft doesn't take barely anything to go fast. They are so light. When you get smaller and heavier, like .177 pellets, you need higher pressure.

Evan, post a thread on it. With pictures and maybe a video. I would like to see that.

Gun Freak, you may need a bit of mouse pad instead of rubber. What's the damage to the button like?

[Gun Freak]

Small dents from the phillips drive. No big deal. Mouse pad would absorb too much energy, I'm just gonna put some neoprene-like sheet rubber disc on to soften the bolt head (it'll probably be stainless steel). Worst case scenario I have to make a new button, not too hard with the drill press.

Looks good, glad you got the hammer working!

Anyway,
A nice new gauge to replace the current clunker

[Gun Freak]

Cool, if I convince my friggin parents to let me use paypal I will get one from eBay.

If you are happy with it, cool.
But I used a very simular hammer, it didn´t work very well because it`s too light, and from the video, looks like cocking the hammer is hard, a very bad thing if you want to combine the reload mechanism with recocking hammer.

Don't worry. This setup was temporary to see if the valve would open with the intended hammer type. That striker is not final, neither is the loading procedure. It was only hard to cock because I was using a ghetto setup and only cocking one side. In the final design, there will be two handles, one on each side, so it will be easier to cock. I'm talking about something like an M4 charging handle (two fingers).

And yeah I was planning on incorporating the cocking into loading if possible... But we'll see.
