It was this or dig up a tree root.
Step 1: Template
To get the scale I used the kids sidewalk chalk and drew it on the garage floor.
Step 2: Transfer
Once the bottom has been cut, lay each piece on a full sheet of ply wood and then trace. This will soon be the top.
Step 3: Router
Before cutting the top, run the dado the full length ( about 1 1/"2 from inside line). Do the same for the bottom portion for this is the track in which your bending ply will sit.
Step 4: Bending Ply
Make the grain go from north to south. Cut to length but don't install until you attach the base to the stump.
Step 5: Level the Stump
About 30" from ground to base. Chainsaw works well.
Step 6: Build Support Box
I used the chainsaw to seat the 2x4 on each side.
Step 8: Install Sides and Top
I used a couple coats of stain.
Step 9: Add Poly
Make sure to drill a couple of small holes through the poly near the center of the box to relieve the weight of rain water.
Step 10: Build a Cover
If a cat sees this, you know exactly what they would do. Build a cover.
