i need help!

[Old Guy]

The way I build the turntable I machine to round plates 1 3/8" thick the other 1/4". On the bottom one I machine a groove that holds a #35 chain I make sure that the groove is the right depth to allow the chain to meet just right inserting 2 pins into the ends through the plate leaving normal chain gap. Now I machine a radius groove on the top of plate 1 and bottom of plate 2 to hold balls from bearings. next I insert a shoulder bolt in the center taping threads in the bottom. With the chain in place I now mounted a low speed DC motor with proper gear for chain on one side, works great.
