You can build a fire around a makeshift log-loader and let the thing supply the fire with fuel all night long. You can also customize it to meet your needs by making it bigger or smaller than what is described in the steps outlined here.
This hack works best with a fire pit as a raised campfire will burn away the feeder that’s resting above it. The first step is to build two frames that will support the firewood. You want to place the frames on either side of the fire pit that you are going to be using. Each frame consists of two vertical support logs as well as a crossbeam or two, depending on the size of the feeder that you are creating. You will also need another, smaller beam for each of the support logs as well. Cordage will be helpful, but it is not necessary. You can also easily find some forest debris to use as cordage as well.
For this example, let’s work with support logs that are about 4-6 feet long and at least three inches in diameter. You want to place them at a 45 degree angle to the fire so that you are forming a “V” or “U” shape after the frames are installed on both sides of the fire. You take the smaller support logs and place them at a 45 degree angle underneath the taller ones to hold them in place.
All you need to do now is stack your firewood horizontally across each of the support logs and let them roll down into the fire as the wood burns and disintegrates. As each log or branch is consumed, another one will roll into its place and the process will continue over and over again.
If you want to use larger logs, simple use thicker wood for the frames and consider adding a support beam or two in order to make the frame more structurally sound.
