This is a project that I have been working on this winter. It is a DRO for my lathe.I found this DRO kit at
http://www.shumatech.com/products/dro-350/index.htm . You order the bare PC board from shumatech and
the parts from Digikey and Mouser Electronics .
This is a picture of the bare PC board.
This is the kitchen table with the pc board and all the parts.
This is the finished dro attached to the digital scales that I got off E-bay.
I attached the digital scales to my Grizzly 9" lathe.
Well the project is finished. It has been so cold in my shop that I haven't made anything on my lathe with the new DRO.
This is my Harbor Freight mill (model 981). I added a DRO. It is for the X and Y axis.
The X-axis is on the silver looking piece sticking out the left side . You can see the Y-axis
along the bottom. I'm going to look on E-BAY for a six inch scale for the Z-axis.
