This deserved a new thread

So basically this one is similar to v1 except it uses a different type of piston and i made it with out that ugly outer barrel that i had on v1. its also a bit more powerful

Specs:

Main valve: Hot glue piston with a Nerf dart tip as the sealing face (screwed it on)
pilot: schrader
barrel: 4mm (unfortunately plastic )
chamber: crayola marker
firing pressure: yes, again, 150 psi

Here it is:


without it's disguise:




the screw holding the nerf tip to the piston:


It also serves as a tiny nerf gun

That shot was made 5 mins after filling. As you can see it has NO leaks

It passed the idiot fooling test (i asked my friend if it looked like a marker) I was trying to make it look like one of those double sided markers (yes they do exist) and it turned out pretty good.

I was very surprised at the result of this test:

Is this the smallest shotgun round ever???!!!


proper fps testing to come... :

firing pressure: yes, again, 150 psi

...... you must be kidding right?

besides from that, looks like a normal marker with a barrel sticking out..
makes me wanna finish off my coaxial, which was a failure.

hahahha ya thats what everyone says. dont get down if your co-ax doesn't work on your first try. This is actually a v3. the first was a total failure, the second worked fairly well and it wasn't until this one that i got it just right. good luck!

That much power within a crayola marker case?! that's insane! I love concealed guns, especially penguns like this. great job, and love the ammo

cammyd32- thanks, i was really surprised at the can full of water test also.

Good job, but you should really consider stronger construction and use of a shock pump, the difference in power will be a revelation.

remember, I live in thailand and it's extremely hard to find anything pvc, copper, or steel here. (actually i lied about the pvc but non of it is rated ) higher pressures would be great though. My wood shop teacher does have some small id copper which would be great for a hp pen gun...

You don't need any of those, all you need is brass and epoxy

all you need is brass and epoxy

okay you've convinced me, i might as well give it a go (I got lots of free time )
