The difference is that you are not holding the explosives in your hands when you detonate them. Thus, your comparison is invalid, and this handheld launcher is a far greater risk.

Spanerman, BBQ igniters work fine in hybrid applications.


ehmm dude it aint invalid...
If i make explosives.. ive got them right in my hands.. and the problem is i work with acetonperoxide... if u know a little about energetic materials u know u shouldend make AP.
Even the synthese is dangerous a runaway could occur if not enough cooling is applied
And I think explosives are farrrrrrrrrrr more dangerous than this NAUGHTY launcher of mine..

Cheersss

Plzz post something usefull to the thread..
I don't care that you are starting tommorow.

as for the sparkplug... it works really nice as for welding a normal electrode welder can be used metal from the fitting and from the sparkplug are almost simular.
As for tapping u need a m14x1.25 tap 8)
Ive got this electronic bbg igniter.. it cost only 2 euro's it work fine with a spark arc of 0.5 too 0.6 mm and it fire about 10 sparks a sec... :twisted:

I would say weld it in a fitting and place it in a TEE it's much stronger and more easy to seal of.
The tap is a special tap get it at a car depot 8)

Yes, your comparison is invalid. You do not hold explosives in your hands and intentionally detonate them. You DO hold a 7x hybrid in your hands and intentionally ignite the mixture, which is far more insane, and much stupider than properly synthesizing AP.

hmm ok but if i were you .. if u have the chance let the spark plug be welded in a fitting. its more easy.. its only an advise you can do anything with it u want 8)
The seal is much better.. i tryd tapping to but i didn't gave me a good seal

i thing threading it into mymain chamber is a better idea...i know it slighty redused the integrity but....its better tham having the spark waay off out of the chamber.....

I have heard that if the spark is in the middle it slighty increases your power.. but its not very much.
I would say keep your chamber strong.. probably better... but tapping in the chamber is OK too..
and if i were you try to cover the spark plug in something.. so if the spark plug would explode out of your chamber that it wont hurt you..
i trust a weld more than a tap.. :P

that really worth the try..
I ment i hope your tap is strong enough to held the pressure so that the sparkplug wont burst out..
But what your saying is a good option 8)

A gasoline engine is effectively an 8x hybrid, and a threaded in spark plug holds up to thousands of firings per minute, so there is any need for welding.

ehmm dont have a chrony but my chamber volume is 490 ml and C:B is 0.3 to 1 so i think supersonic at 4x or 5x mix
I shot with a little bolt probably 3 too 4 grams through a house door..
damage pics soon
soon i will be shooting with MAPP gas that should be a crap load of power
also i edited my cannon al little wich i will post it looks really clear and nice now.. and it look like a rifle also ignition is edited its now on the handle so u can shoot it like a rifle now :twisted:
A friend of mine has a gauge for measuring bars at car..
I will connect it to my hybrid and measure bar increments at different mixes like 2x mix 3 x 4x 5x 6x 7x
Cheers
