Often I am asked, after I find a stump or root ball, what are the procedures to finishing it out: Here they are:
Finishing a Root Ball or Tree Stump
After you have found your root ball or tree stump that you know would make a beautiful table or lamp, you will need to finish it. Here is the process I use:
Leveling the Piece: Cut the bottom in a plane perpendicular (at a right angle) to the length of the piece.
Set the piece on a level surface and using a level, draw a line around the piece at the height you want. Cut on this line.
I use a chainsaw for this, but a sharp hand saw will work also.
Sand both top and bottom surfaces to desired smoothness.
Stumps and root balls take time to dry-often years. If the bark is tight, the piece probably is not dry. Remove bark with a draw knife or chisel.
Physically remove rot and bugs. Smoke and heat will make the bugs jump ship. A bonfire works great. Place the piece close to the fire and heat it up. It will take time to heat up in the middle because wood is a good insulator. Wood doesn’t burn until it reaches 500 degrees F. If you get the stump plus 200 degrees, it will kill any eggs, larvae, etc.
Use a good quality polyurethane to finish the piece. Be sure to coat ALL surfaces: top, bottom, etc.
At least 3 coats are required to seal the piece. The polyurethane will harden the surface and stabilize minor rot. Rotted areas really drink the polyurethane-use it liberally in soft areas. Sand lightly with very fine sand paper between coats. Let dry completely, and it is completed.
