first nerf/pneumatic sniper

[ozzioutlaw]

hey guys first post but always on the site looking at ideas for a gun now i came up with my own. so here it is my mussel loading sniper only tested @200psi so far but bottle and trigger valve rated for 1500psi i need to find a new pump source mine cant get any were past 200 psi any one got any ideas that'd be great,
any way here it is in its early stages (b4 fiber-glassing and paint)
not to harsh comments plz this is my first go
thanks

Looks good for a ghetto launcher, are you using the pressure washer handle as a direct valve? You should put a BB chamber at the breech for full auto fire, HPA + BBs is fun

A good cheap source for HPA is a fridge compressor, quick search on the forum will reveal plenty of link.

Nice job especially for your first. The only thing I would say you have to add is a paint job, It will look awesome

great cannon. You need to get yourself a fridggy!!!

Remember, you've weaken the tank a bit by drilling a hole in the bottom for that fill valve. You'll be fine with a fridge compressor(<500psi) but don't try to fill it up with CO₂ again. You won't have much of a safety factor.

Please do add some fiberglass work to this; you'll be one of the few people on this site who has. It's great stuff but tricky when you first start out.

Thanks guys and yea I want blue camo paint on it any one have a sketch or detailed picture of how to set it up I have a small bar fridgethat I could use. And to be honest its really hard to get bb gun parts into Australia their not very keen on bb or paint ball parts coming into the country

watch out with the bar fridge some dont have a compressor but use ammonia and hydrogen to cool, they are called absorption fridges, very dangerous to open!


where in Straya are ya? im in Melbourne

It's not too hard mate, just need to know people.

And careful with the bar fridge, like Crna said, I had one burst in the caravan I was living in at the time, in winter. I was sleeping outside for a while, sh­it sucked.

Here's an example of an absorbtion cycle fridge:



And some good advice:

Do not open that one. Look up absorption cycle. There is no compressor.
It is full of ammonia. The electrical item is a heater. These use a boiler to separate Ammonia and water. The system is under high pressure.


http://en.wikipedia.org/wiki/Absorption_refrigerator

A single-pressure absorption refrigerator uses three substances: ammonia, hydrogen gas, and water. At standard atmospheric conditions, ammonia is a gas with a boiling point of -33°C, but a single-pressure absorption refrigerator is pressurised to the point where the ammonia is a liquid. The cycle is closed, with all hydrogen, water and ammonia collected and endlessly reused.
