If [Paul Degenkolb] really decided to make this on a whim one day (like he says he did) we think he should quit his job and go into a full-blown state of whimsy for the rest of his life. The Margarita Machine makes five gallons of slushy intoxicants in a quick and relatively quiet process that will have a backyard full of guests lining up not just to imbibe, but to see what the heck you’ve come up with this time around.
It’s easy enough to see that the vessel is an Igloo cooler, but where do you get a motor and blade assembly strong enough to turn ice cubes into slush? Just hit the home center and pick out the Garbage Disposer model of your choice. With the ball-valve serving spigot closed, the disposer sucks down the liquid and ice, shooting the pulverized mixture through some PVC pipe back to the top of the cooler. This circulation helps to mix things up, but at times [Paul] uses a glass as a plunger to wrangle rogue ice cubes.
Sorry folks, doesn’t look like there’s any video of this in action.
