Here is my 9x19 lathe I got from Harbor Freight. I have added DRO scales and the original metal stand was replaced with a sturdier one made from square steel tube.
At some point I'll get around to making a remote display for the DRO positions so I can cover up the scales to reduce the risk of shit getting inside the sensor. Only tricky part about decoding the signals the scales generate is the ~1.5v logic levels; I don't have any logic level converters at the moment.
