True, i just like the clean holes the drill leaves, and i worry less about distorting the can versus trying to puncture it with something. luckily i was able to find a different charger that will work, and made another stove yesterday, 8 holes on the outside and none on the inside, and havent had any fireworks yet :)ill do some research and try the center burner again later.

thanks pappy!
