Here are some pictures of my Snow Gun. I bought it From Mike Rice at New Mexico Skies. Well made and easy to use. Finding the CO2 was the hardest part. I found what I needed at Linde Gas. It's called Coleman Grade and is 99.99% pure. I had to have them make the tanks with the dip tube so I went ahead and got 2. They are 20lb tanks and I move it around on a Gas truck I bought from Northern Tool. Note: The 20lbs refers to the amount of gas, not the weight of the tank !!
