Not a Flamethrower

During the summer of 2022, I decided that I wanted to design and build a "torch" that was capable of swiftly removing the weeds in my backyard as well as effectively removing wasp nests that had come to my attention. Now any normal person would probably get weed and wasp killer, but I have something that most people don't... An engineering background. I based my design around a roofing torch that could be purchased at any local hardware store, where I then went and designed all new plumbing to ensure the fit inside the casing. Now I do not want to have you fooled, I used a NERF gun and retrofitted my system inside the gun. This "torch" features 2 flash back regulators placed on either end of the gas fuel line to prevent any "issues" that could occur during use.
