pull springs
some gas pipe
elbow
T piece
adapter
bicycle valve
some scrap material
rope

What does the name stand for?

What is the operating pressure?

How's accuracy? Range? What weight are the airsoft rounds?

What's the estimated opening time for the valve, and what size is it?

What's the volume of the chamber? Where do you get 10mm airsoft rounds? What's the barrel material?

Why didn't you give all these specs to start with?

[sniper hero]

name:high power screw sniper (although the scope is still to come)
pressure:for now +- 4 bar
accuracy:I have to practise a bit but a can at 8 80%
ammo:my ammo is for now screws and it works fine
volume chamber: 1liter
barrel: aluminium (10mm is outside diameter)
opening time: ? I will post some video's tomorrow

Your chamber is a gigantic over kill .

[pizlo]

Well it isn't easy on the eyes, but its a start. A paintjob, and a better valve would make this thing much nicer.

[POLAND_SPUD]

you can easily convert it to 15 - 16 mm barrel suitable for marbles... since your chamber is HUGE it won't be any problem.....
also i think you should buy a full metal ballvalve (you know the ones with one long handle)

[elitesniper]

Or, since he already has that set up he can easily convert it into a barrel sealer

[sniper hero]

ok so the ball valves with the long handle open quicker?
I don't know if I can find a marble barrel
but if I find is this lengt ok?
I know it looks a bit strange but its quite ergonomic.
I want to put a scope on it, has anyone suggestions for the best way
(it,s a scope for air rifles so distance between eye and scope is quite small)

[POLAND_SPUD]

if you use a ballvalve with a long handle you could drill a hol in that handle - so you could get rid of that piece of steel that turns the ballvalve

mounting a scope will be a problem on your gun because of the valve

[sniper hero]

yes I know it's a problem but if I make it behind the valve it's the right distance between eye and scope



I found a piece of iron exactly fiting in the barrel with some tape it shoot trough a thin metal plate
the screws fit exactly too but are very light (1gram)

[bluerussetboy]

Wow, that is fugly.
That 'springer' setup must make a ton of noise when you pull the trigger. Puhleeze, if anything make that chamber smaller.

BTW nice use of your rube goldberg gene.

[ghostman01]

that screw looks like it has been into somthing with red liquid in it

[pat123]

looks powerful, it needs a paint job though.

that screw looks like it has been into somthing with red liquid in it

uh-oh

[ghostman01]

yeah i hope thats paint, lol

[bigbob12345]

that screw looks like it has been into somthing with red liquid in it

i was just about to ask that

Anyway nice gun
isnt the preetiest and the ball valve is definatly deacreasing performance but other than that I like it.
looks like a fun little plinkler
