I extended the ignitor tip to be in the middle of the 3" T section so that it ignites the gas evenly in the center causing equal pressure as the gas expands outwards. I also drilled a small hole right into the T chamber for allowing the WD-40 or any other can I choose ( with the correct tip ) to spray directly into the chamber without having to unscrew the ends every tip I want to recharge it!
