Spits are rods that hold meat over a flame and are made from either wood or stainless steel. They are easy to make and only require a small amount of time if you choose a stainless steel pole that can cook both large and small pigs. And don't forget to make a support system to hold the spit.
Purchase a 1 3/4-inches-in-diameter stainless steel pole that is longer than the pit. The pit should be 1 foot wider on every side than the pig. So if your pig is 3 feet by 2 feet your pit will need to be 5 feet by 4 feet. On each side of the pit you will need a support system of two side posts in the shape of a "Y" to hold the spit over the heat.
Measure and mark the mid-point of the pole. Mark off every 2 inches three times on one side and three times on the other.
Drill 1/4-inch-wide vent holes at all of the marked points to encourage heat flow.
Clean the pole before pushing it through the pig.
Buy a small motor, like a gear reduction motor, from a home projects store and connect it to a metal pole that will fit snugly inside the spit to slowly rotate the pig.
Protect your hands by using heat-resistant gloves when touching the spit.
