You should have seen my explosives.. that's insane..
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...

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)

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)

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..

well spark plugs are used in engines (duh) they handle a shitload of pressure....i may tap/thread then weld into the chamber....worth a try

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)

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 shit 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

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
