The bevels on each end of the top are a bit of a challenge. You can either use the table saw and jig to make the cut or cheat like I did. I just marked the angle on the edge of the wood and used my disc sander to sand to the line. You have to go slow to keep things straight but it was fast and it worked.
All the wood for the clock is 1/2 inch thick except the legs. They are 1 inch thick. I tried to make the legs from 3/4 inch wood but they didn't look beefy enough. If at all possible use 1 inch wood for the legs.
