bolt action marble gun

[rhys_pesantsrevolt]

ok so I am getting the parts for this gun in 4 days and the gun should be done on that day

my design basicaly i have a ball valve to fill the primary chamber from my 800 psi air tank. Then I have a second ball valve which I open to fill the secondary chamber the air goes through a regulator the reduce the pressure to 90 psi then because I have yet to come across a sprinkler valve I am using a spring loaded ball valve as my main valve the loading system is bolt action.

what do you think?????

[MrCrowley]

Sprinkler valves are available in Aussie btw.

Just ask some of the other members, most get them from bunnings I think.

[experament-u2]

yep bunnings or comb through a dump shop i got loads of cheap valves there

[The Kid]

yeah my bunnings sells like 5 diffent kinds of sprinkler valves blow guns as well

[watto]

ball valves open real slow even with a spring, In bunnings the sprinkler valves are in the retic section in big wooden tubs usually, or try a sprinkler shop like 'total eden' or 'hugall and hoyle'
goodluck

[rhys_pesantsrevolt]

thanks now I just have to get a ride to the bunnings at thornleigh to get one

Actualy the sprinkler valve would make it easier to fire one handed which was my idea for this gunif I have a 15cm long and 12mm round secondary chamber at 90psi and then a 10mm barrel what sort of range do you think that will get?//

IF you want great performance, yea sprinklers good, QEV is better if you can do it. Mcmaster has them

[The Kid]

i don't think mcmaster ships to aus

[MrCrowley]

They don't.

[The Kid]

i know they don't that was just ment to have a bit of sarcasm in there.

[MrCrowley]

[The Kid]

Haha okay, I was just supporting your post then
