G'day.

Check out my attempt at a spring pistol.
http://www.spudfiles.com/forums/spring-pistol-trigger-issue-t19942.html

I'm having the same dilemma. Ive tried a few ways to get it to cock.
I think ive got an idea that will work, Just have to get back to the laser cutter and get it cut.

Hope ...

I've thought of a few things that may get the gun working. I need to wait until I get back to work so I can use the lathe.

I know that 50 feet isnt alot, but that distance is considering that the rubber bands only provide 1/4 the power of the spring, And at the moment whilst im not working and dont ...

G'day all.
I've had a little luck with installing a shorter, stronger trigger spring. It allows it to lock on to the catch face and allow the gun to be cocked and fired by means of the trigger.

But this is at the expense of power (at the moment) as I use red postal rubber bands ...

I was thinking today while eating Christmas lunch.

If I were to increase the load created by the trigger retaining spring, and maybe get a less powerful spring for powering the gun but with a higher spring rate, maybe the gun will cock, Im not sure if it will, But I guess time will tell.

Although ...

Thanks Maverik94, Its not uber-powerful, but thats not what I was looking for. All I wanted was a self-sustained pistol, nothing that required a pump. and besides, this project was only an experiment.

I'll be sure to post it in the showcase when its fully done. Im not planning to paint it, I was ...

I see what your saying Gippeto, I have my trigger system the wrong way around. the pivot needs to be in front of the trigger point, That would require some kind of 2 piece trigger. I could do that, it would just take a whole lot of redesigning, I could play with the strength of the trigger spring to ...

The piston spring is pretty powerful, Ive looked at the avenue of a stronger trigger retaining spring, just gotta get one and see what happens, this may result in the trigger being to hard to pull.

I had a thought about knurling the trigger area and decided it wouldnt be a good idea as the second ...

I have access to a lathe, mill and laser at work so I thought I might sneak in a foreigner just before we finish work for the year.

It fires pretty good. A 6mm BB saboted in a plastic bag is good enough to enter a can at close range. Im not expecting "real" air rifle power. Just something to play ...

This is one idea. Machine a very deep inner taper. I may not even have to manipulate the trigger at all, just allow it to rotate more.

any help would be fantastic.

PS: Sorry for the Triple post.

This image shows what it is meant to look like when its been cocked and ready to fire.

The issue I have is that the triggering sequence (of pulling the trigger down: rotating it on its pivot, hence releasing the piston and spring).

PS: Sorry to double post, Im making pictures and posting them as I ...

G'day all.

Its been a while since ive been on here with work and everything, anyway.

I've got a new project 99% finished. Its all been machined as good as I could get it. I'll out up some photos as soon as I can. Looks pretty menacing as its been made out of steel that's been machined and laser ...

They dont fly straight because of the magnus effect.
Im not exactly sure what the hell the magnus effect is.
But I know its got something to do with it.

Making the marble spin on an axis will help significantly.
Applying backspin will increase distance.
As for accuracy, Im assuming, that the marble ...

Its a good skill to know. very usefull. My friends a locksmith and he taught me how to pick locks, its very easy once you get the hang of it. He can get through Deadlocked doors in 8 seconds, its amazing.
