aw, no fair. i made one of these 4 yrs ago in my tig welding class as my own little side project. i didnt use the neck i welded together an aluminum ring and a top for it and welded them together. its shorter than yours. not as clean but still runs very well on SLX denatured alchy. ive run it on acetone, white gas. for some reason tho, mine wont simmer as well as yours will. I need to have a pot or can on it to create a little more vapor pressure inside the burner to keep the flames consistant. I pour a little fuel around the stove and light that, it preheats the stove and makes for a less knuckle torching experience.
