plywood. In between these two plywood disks I mounted a 12 inch lazy Susan bearing so
the front could be turned. This was screwed to the 2 x 6 under carriage and the 2 x 4 cross
piece. The front wheels were then screwed to the 2 x 4 with pipe flanges and 8 inch black
pipe that runs down to the axle. For the axle to turn I used a 3/4 inch to a 1 inch T and ranthe axle through that. The end caps on the outside of the wheels are plastic flower pots
that are screwed on the center of the wheels. The back wheels are mounted the same way
but screwed to the doubled up 2 x 4 in the back.
