If you have one of these Harbor Freight Mini Lathes I have found a few cheap upgrades
first we have a quick change tool post with 4 tool holders
here is a turning facing tool in a toolholder, its small but perfect size for this little lathe
next we have a cheap DRO thats digital readout
this shows the scale part I mounted to my cross slide, the scale comes in all kinds of lengths and can be cut
the readout can be zeroed anyplace has inch or mm a nice big numbers, it has a magnet on the back for holding it
The quick change tool post and holders was about $70 and the 2 scales with readout was $60 for both
I still need to mount the other slide, more info as I use them and see how they repeat
