So I have been getting back into using my Chinese made Harbor Freight Mini-Lathe (see more here: http://diy3dtech.com/mini-lathes/) and wanted to add a Y Axis DRO (Digital Read Out) to it but didn't want to spend big bucks so designed up one of my own using an economical dial indicator I got off Amazon (see more here: https://amzn.to/2FUoo2G ) and if you need to extended the reach of the indicator, you also add an extension kit such as this https://amzn.to/2WdmakH and or a tip kit such as this https://amzn.to/2MsesPb depending upon your needs.
Because the dial indicator had to be moved over because of the control knob, I used 3M washer on the end (you can see it in the pictures) to make contact. Another option would be to get a Tip Kit (see more here: https://amzn.to/2MsesPb). Additionally I have also used a1/4 magic nut for the mounting too!
This has turned out to be a super handy addition to the Mini-Lathe and I have also have the Open SCAD code posted on our Open SCAD site if you want to get a copy here: http://openscad.diy3dtech.com/mini-lathe-3d-printed-y-axis-dro/
Also I used M3 bolts and washers so if you're looking for an M3 kit (which is super handy to have), here you go: https://amzn.to/2T55bPn
