This is my new hybrid sniper.It works on the principle of my coke bottle hybrid.As I said for my pistol it has a great recoil.The time from the boom of the gun to the moment of impact when shooting a battery is vrey little comperad to my other guns=>so it is quite powerfull.It is very noisy.I like the sound of the chamber when filling with air 2 seconds befoure the boom.

But you should remember that you must treat the bottle with hot wather to reduce the volume and encrease the ticknes of the walls.

Yeh,i new about treating them with hot water to make them stronger.The only problem now is getting a continous spark ignition,as they are not the easyest thing to find,may i ask what type of ignition you use,and roughly how much fuel you put in your chamber.I plan to use a 390mL chamber for the strenght is that the type of bottle you got to crack at 4x mix?

I put a hot wather in the bottle but there is a little problem.Because the bottle is about 7" tall the wather presure in the bottom is bigger then the presure on the top, the bottom has a little bigger diametar then the top.That isn't very good bacause the bottom is the weakest part of the bottle.One solution can be if we use a much lighter liquid then just a wather.Other is to fill the liquid and in the same time to dive the bottle in a pot or something.As for the amount of fuel-it doesn't matter how much I put becausse there are little leaks in the chamber.That's why I don't pomp directily, I use a bottle wich gives enough flow to compensate them.

i dont reccomend that, as to many people here are enimies of high voltage=] i got the bejesus shocked outta me my a taken apart disposable camera. by the way rambo, what is that you use for the contiuuous spark. ive seen it on your other hybrid, but ive been wondering what it is and where i can get one
in the upcoming presidential election, there will be several candidates who will be running, one of whom is Hillary Clinton. Now WAIT A SECOND!!! I though there was some sort of rule that prevented someone from serving more than two terms in office. Vote Against Hillary: Presidential Elections 08

I took it from 1lv shop(1lv=0,625$).It's a cheap chinise cooker ignitor.In my hybrid the margine between the electrodes is not more then 1mm.First-that way the mix will only ignite if it is almost perfect and second is that the ignitor changes it's preformance and I want to be sure that it will give a spark even at 4 atm.How much do you think will be the shipping costs from Bulgaria(it's between Greece Romania Yugoslavia and Turkey) , to where you live?

Shipping costs would probably be more than the sparker itself :)
It took a while for me to find one, too. You can check your local 1 dollar shop, flea market, supermarket etc.
