Meade ETX 125 Telescope manual focuser knob modification

Step 4Final thoughts

Final thoughts
I've put some white lithium grease inside the fixed shaft, on its outside bottom end, and around the bottom nut. The set-screws are treated with a thread stopper glue.

Everything works flawlessly!
The knob diameter is very comfortable. The dial wobbling is only 2 points. The dial lock (on the side of the knob) allows secure locking of the focus, so nothing would ruin it by an accident.

I've adjusted the scale so the value 1100 is near the end of the thread of the focusing shaft. So I'd never unscrew it completely.

Make sure that all of the parts moves without much of the force. Do not over tight the parts!

The dial on the picture shows 486.5
