Homemade Flamethrower Tutorial

Step 1: Air Compressor

    I wish ever6one would put the parts list on the page, trying to watch the video to get the parts list for those of us that can’t hardly hear.
    If someone has a list I would appericate it

  2. Donald Sammis says:

    Incredibaly crude. The concept is valid, but most DIY guys would make a much neater and safe and reliable package with more suitable hardware. Granted you have to use what you got, but this Rube Goldberg collection is pretty crude

    looks like an easy way to have some fun then have a meeting with the ATF and a federal prosecuter, but I suppose if you say you’re related to the Clintons it shouldn’t be a problem

      Dumb butt, Flamer throwers dont fall under ATF ruling, and are legal in all states except California and Maryland.

    Am I the only one that noticed that the hodgepodge of random parts in the the step-by-step is totally different than the clean very polished version in the video? Especially when in the beginning of the post it says, “Here we have the step by step instructions, but you can find the full video instructions at the bottom of this post.” which the video is NOTHING like the step by step. It uses a pressure washer hose/gun, and a scuba tank not a plugged air compressor tank and some random fittings. Just my 2c

  5. Could you make one of these with a garden sprayer?

    Pressurizing it with co2 would be a lot safer.
