just recently got a mini lathe an mini mill an wanted to add a dro but at the same time do it as cheaply as possible while still being accurate an these are 2 ive gotten an used, a 6 and 2 8 but i will be replacing the x axis with a 12 eventually so its just tempary how its mounted now. i justs bent metal up to make the brackets to mount it to the front of the table using the t slot, slotted the hole an printed a bracket that would bolt to 2 existing holes in the center of the base, not sure what its all called, i took pictures to try to help explain. u will need to be able to drill an tap holes for a couple of the brackets to work but if u have mill u more than likely have the tools to do it. the x an z are pretty simple an u use the brackets that come on the scales along with some printed parts but for the y axis u will need threaded inserts, replace the scales back half of the mounting bracket with the printed part with the threaded inserts an it will let it mount to the base with the right angle to keep it all straight with the machine, then u drill an tap a hole in the center of the y table or slide again not sure what its called, still learning but its pretty straight forward, if u need any help just send me an message or comment an ill try to help with what i can. oh also a mount that uses 12-13mm metal tubes, old furniture is where all mine has came from, but that an all the brackets will let u mount the screens to something an it lets u move them all around almost like a nicer dro screen, probably alittle more movement than one of the nicer ones since its so much smaller but it works for me an i hope someone else find some use out of it. eventually i will update the x axis to have printed parts an be mounted to the back side of the table instead of the front t slot but the front t slot lets me move the slide back an forward the length of the bed since it was a little short fot the axis but once i get a 12inch it will move to the back.
