I built a big turntable for my sculpting project. Since 4 ft. x 4 ft. seems a little bit too small for a full spectrum of poses, I decided to make it 6 ft. x 6 ft.
Cut two 4 ft. x 8 ft., 3/4 in. thick oak plywood boards (about $45 each) to two 3 ft. x 6 ft. boards., then cut three 12 ft. long, 2 in. x 6 in. wood bars (about $7 each) into halves to have six 6 ft. bars to connect those two boards.
To make sure the table sturdy I used sixty 7 in. L-angle connectors (about $3 each) and drilled about four hundreds screws.
The funnest part was attaching casters. I used sixteen Titan polyurethane rigid casters (about $10 each).
As long as casters are oriented along the circumferences of concentric circles, the turntable will rotate around that center.
Ready for photo shoot with models!
