Plain old Elmer’s Wood Glue. Lots of it…

It’s very important to spread the glue out evenly.

Clamping with even pressure will assure a good grip. The turntable itself is made up of three layers. The top is 3/4″ ply. So is the middle, but this layer is 4″ smaller the the top & bottom. The bottom layer is 1/4″ ply.

Christina is laying out the casters in a circle. The base is a 6’x6′ platform framed with 2×4 and covered with 3/4″ ply. The casters are being placed on the base with the wheels facing up. The round turntable will sit on top. In the center will be a hole for a guide center pin.

Christina is laying out the casters. Notice she is using a long straight edge (a 6′ level) to make sure the wheels are parallel to each other and thus, perpendicular to the pivot point. You can also do this using a simple piece of string and lining up the center bearing pin of the wheel to the string.

I’m not sure this will work, but the photo here is a link to a MPEG video file. It’s just under 3 megs in size and you’ll need some sort of video player plug in working…

Rico is fitting the drive wheel to the turntable’s base platform. This will have a handle attached and will be connected to the turntable via 1/8″ cable.

The casters are placed to help guide the drive wheel. Otherwise, the drive wheel would keep popping up out of the hole drilled into the platform below.

The cable would keep slipping on the wooden wheels so we had to add some tension. The turnbuckle and pulley allowed us to vary the tension as needed.
