I have a Phase II 4" rotary table that I retrofitted. I am only going to use this table at low speeds and light milling mostly wood and aluminum. Also I only use the table with the controller and never manually.
What I did, and by no means am I an expert, I started by stripping down the table. With the Phase II there is an eccentric bushing to engage and dis-engage the drive gear to the table. I am never going to dis-engage my table. So I found the high spot on the bushing and tightened the set screw that adjusts the tension on the bushing. The bushing no longer moves. I used lithium grease on the gears and I do not plan on using light spindle oil as suggested. After some extended use I disassemble and add more grease. The grease allows for a good fit and also allows the gearing to move with much less friction then the oil.
I also removed the handle and the dial gauges (the scribed dials) since I never use them as a reference. I would think you can leave them on if you want but I did not even try. The shaft attached the handle and held the shaft in tension with a double spanner nut and thick keyed washer. I removed the spanner nuts and washer and replaced the washer with a steel needle-roller thrust bearing and washers and the spanner nuts I replaced with a threaded clamp-on collar. I purchased these items from Mcmaster.com.
I mounted the motor and basicly now have no backlash. I did not add any home position switch, again I would never use it, If I needed I can make a jig to find a reference zero.
