I recently completed a project with my son for a table extension ( height ). The goal was to raise the working height ( 18" ) of an existing table so he could work on it in comfort. Since neither of us has lots of spare cash we used some reclaimed lumber I have ( old 1 x 12 x 8' fence boards, pine, stored outside ). We started by sorting to find decent boards, took them inside the shop and let them dry, just surface moisture so they dried in a week or so. I had the son do most of the heavy lifting, after I demonstrated the proper use of the various tools ( SCMS, Table saw, planer, etc.)

After the boards were dry they were planned down to fresh/decent wood. Once we had enough wood planned the pieces were cut to rough length. The next step was ripping the pieces to the proper width. Final length was cut next, followed by sanding. The legs were made of two lengths glued and screwed to a "L" shape. The top was laid out and stringer screwed to keep them together. The legs were screwed to the stringers and small right angle braces were screwed to the legs, two braces per leg at right angle to each other. We had to wait for warmer weather for the next part; epoxying the wood, There were lots of small knots and splits in the wood so the epoxy was used to contain the defects. A coat of paint and Bob's your uncle. I didn't get any picture of the build, but I'll get some of the finished piece.

Looking forward to seeing the end results!
