Build Log for my Clip Fed Auto Loader

[socoj2]

So something this complicated is going to take a lot of parts.

Ive gotten about 50% of the stuff in so far.
I am going to sell those 3/4 Qevs and use 3/8s

4x 5/8s actuators
2x 1/8th 4 way solenoid
1x 3/8ths 4 way solenoid
3x 3/8ths QEV
4x 1/8th QEV
2x 1.5" Piloted actuator Pulse Valve

Thats a 2.5" T, This is designed based on a AutoCocker paintball Gun, and will work with the same action. The housing is 2.5" PVC while the bolt will be 2" PVC. I should have the remainder of the gear in middle of January, so im hoping to have something assembled by feb 1.

The electronics for this are all on a Custome PBC.

Looks like a good start. Care to give any details on how it's going to work?

[socoj2]

Cylinder is going to move the bolt back.
New shell drops into place cylinder moves the bolt forward locking the shell.

FIRE

Cylinder unlocks the bolt
2 cylinders then Eject the old shell
New shell drops into place
Cylinder locks the bolt

FIRE

Rinse

Repeat

looks fiendishly complex and there's spent cartridges involved, you have my attention looking forward to seeing this work, since you're using standard components you're practically guaranteed success.

Yea this is to shoot Nerfs for paintball. So i have to use 7"x2" pieces of PVC to hold the nerf so i can force feed it.

[jackssmirkingrevenge]

So is it going to be similar this then in terms of mechansim?

[socoj2]

Kid of that cannon has several Problems.

1. Recharge Rate.
2. Cyclic Rate

Each barrel can only fire every 2-3 seconds due to the time it takes to recharge the roughly 60 CUi chamber.

Mine will take under 30 ms to do the same. Mine will also not fire if it is under charged.

The way he has his cylinders set up he moves the whole barrel forward about an inch. That is a lot of inertial mass to get going and move at a high rate of speed.

I have a 8" bolt that i move about 1". The barrels stay in the same position.

THe loader is similar except do to mine ROF, i have a force feeding mechanism behind mine. And my clip is 16 Catridges.

How much was that really big QEV?

[socoj2]

How much was that really big QEV?

Its not a QEV its a 1.5" pilot Assisted Diaphragm Valve. with a CV of 53. It has a 4" diaphragm over the 1.5" opening when the pilot is released it provides sickening flow, from the vendor these are $220 each

Action is Almost exactly like a QEV speed is about the same.
The chamber is just not filled via the Input..


THink of it like a bad Ass Sprinkler valve at 1.5" with a faster action

I have 8 of them now i can sell you one for $100+shipping they weight about 3 lbs.

[cwazy1]

wow 220$ thats nuts, cuz you can get em on ebay right now for 10$

[CuddlyBurrito]

can't wait till i see some building

[socoj2]

wow 220$ thats nuts, cuz you can get em on ebay right now for 10$

got a link?

[ALIHISGREAT]

damn i wish i had a 1.5" pilot assisted diaphragm valve, is a Cv of 53 good? because if i find one on ebay i will buy it despite the bsp-ntp problems i would have

edit: $100 + shipping is very tempting, 1" qevs in the uk are ~ £80 which is $160 dollars so £50 for a 1.5" is a good deal although as i said above i would have thread problems
