The process for creating StumpChairs is easy and requires only a few simple tools.
A short documentary about the project can be viewed at https://vimeo.com/52310940.
If you would rather repair the chairs then turn them into public art installations instructions for doing so can be seen here: https://www.instructables.com/id/Chair-Repairathon/
You will need the following tools and materials:
A chair, a stump glue, wood screws, a drill, a set of spade or forstnerr bits a driver bit, a chisel, and a hammer.
Step 1: Find
Stumps are also very common in many cities due to widespread tree removal.
Step 2: Break
Step 3: Drill
Start off by positioning the chair back in the desired orientation and mark off the locations of each spindle with a Sharpie.
Next match up the spindle size with a spade bit. Usually you can get really close because chairs are made with standard size spindles.
Drill one hole for each spindle at the appropriate size starting with the two largest holes. Make sure the holes are at a bit of an angle backwards so that the chair has a bit of a recline. I usually drill farther than necessary just for good measure.
Step 4: Glue
Next align the spindles in the holes. This may take more than one person because they tend to move out of place when the others are being lined up.
In order to ensure that the chair back is sturdy it is often a good idea to tap it in with a rubber mallet. Hitting it with your hand will probably suffice.
Step 5: Screw
Step 6: Sit (and Share)
Sit on it and enjoy.
