This I a easy and fun project to make and a good way to provide seats around a campfire. This bench can hold alot of weight and will last a long time (longer if finished). And to take it to the next level you can even burn or carve a design on the surface.
Step 1: Step 1. Get a Log
Step 1. Get a log that has either already been split down the middle or do it yourself with an ax and wedges. I found mine already split down the middle by lightning from a poplar tree. I cut it to 3 feet and it is about 3 inches thick.
Step 2: Step 2. Flatten Surface
Step 2. Use any meathod you want to flatten the surface as much as possible. I used a draw knife and some planes to flatten the surface, bit I guess you could use an electronic plane or an angle grinder with a wood wheel.
Step 3: Step 3. Prop the Log Up
Step 3. Find some rocks as I did, or you can use some logs to prop it off the ground.
Step 4: Step 4.
Step 4. (Optional) Finish the surface. I left mine unfinished to leave a natural feel.
