I sometimes make gavels to give as awards at speech and Debate tournaments
I also made some gavels for debate tournaments. These are over 12" and made of pine.
This is a small (12 inch) oak gavel. I made it from shop scraps.
This is a three foot long solid oak gavel I made. It went out to the top Parli speaker at the Truman tournament.
To give an idea of the size of the gavel. It is pine that has been stained darker.
