Depends on what you're trying to do. I've got a 1.5" QEV on my golf ball gun.... I wish it was bigger.

But not the ( UK) piston type.
I don't need to explain to you what kind of a snake a "Floa Constrictor" is right??

I lost a cat to one of those. They are dangerous.

Like this?

Any updates on a production design?

[Sam@UoN]

I should have the pro/e models done either tonight or tommorow - i've found a 2" high pressure PVC TEE that should do nicely and some 2" - 1.5" reducing bushes so that would leave a cavity where the 1.5" piston seals...

Anyway I will post when they are ready - right now I'm being forced into bloody food shopping with the mrs!

Thanks for all your help thus far fellas

Will do a better job when i have more time tonight but here is a quick screen grab...

[Sam@UoN]

here is a link to a part of a video that ive made



let me know if anyone can see anywhere for refinement

I should also say that whilst they are not modelled the is an extension spring between the bolt and pison and an end cap on the left with a damper screwed into it...

[Technician1002]

Very nice. I like the animation. My only concern is the peak forces where you decelerate the piston. Do you have plans to absorb the kinetic energy of the piston in a safe manor?

[Sam@UoN]

Yeah a 60J spring damper assy - will work a treat
