Hey tnx, that's nice.

How big does the chamber have to be?
And what pressure do i need for just shooting 'not lethal paintballs' ?

ok, tnx.
So what do you think of my 2th design?

Yes!.

Is this design better than the otter one?


/edit:

What pressure do you recommend? (it dont't have to be lethal )

The spring in the green part will push it back.

Hey,

I made a new design. Which is - i hope - better then the prervious.
Less parts, so less work

I didn't draw the trigger system, but i have plans for that. I think the left piston will not go back automaticly, but ik can make a handle or somthing for that.

@fretmelter i see the leak, ik will use one more o-ring to fix that.



Tnx for all your comments, i will try to make a prototype soon.

eeh im sorry but what is "gravity feed"

my english is a bit poor

@thespeedycicada

Tnx for your reply.

Near which valve do you thing the air wil leak out?
When the valve is in the middle, all gaps are covered...



(btw: who is jsr ? )

@Davidvaini
When i make the prototype, ik will make more gaps, so i think the air will release fast enough

Hey guys,

I've some ideas for a diy paintball gun, i've never done something like this before, so can you people check it?

A picture says more than 10^10 words, so check my attachment below.

Darker blue = Higher Presure
