    If you peek at this ebay auction, a fellow actually has some photos of a DRO mounted on one of those:

    Cool. I think that I can come up with something from there...... the main problem that i have is the quill. It doesn't have a standard open quill and i don't know how to mount my scale on it..... anybody have any ideas? Thanks

    Can't help you there. I got a G0619, so I've got a quill built in.

    Chafik,
    very nice setup. I like the cover over the scale. is that lexan or plexi? i am thinking of doing something similar. i think that i am going to put a scale on the column like you did but would also like to have one on the "quill" so that i can make accurate drill depths. the only way i can think of doing it is making a bracket to hold the bottom part of the scale to the non rotating part of the spindle and making a bracket to keep the digital counter stationary and leaving the top part of the scale free floating, but i was hoping someone might have a cleaner set up.... anybody? thanks a lot for you help.

    Not sure if it's Plexiglass or Lexan, I had a small sheet from home depot (the ones with the blue plastic backing), held it in one of those Black and Decker Workmates, went back and forth with a heat gun to soften it, then
    bent it.

    Once I built the Shumatech DRO, and got my Ebay scales, the whole thing was a one day job, using mostly scrap parts I had (including a lot of hex standoffs and corner aluminum).

    I was installing the DRO while keeping in mind that this X3 would ultimately be converted to CNC.

    Exclamation Z axis - DRO for the quill

    You could make a quill clamp ( God knows Seig left way to much hanging out ) and mount a scale unit to it.

    Here is a shot of how IH does there quill unit.



    There are simular scales with outputs to your display if you are not reading the head position.

    Arrow Update: Found bolt on kit.

    I was just looking at the Arc Euro Trade X3 page, and as I scrolled down, there it was a bolt on kit for the quill DRO scale...

    Check it out - Arc Euro Trade X3 page.

    When you mount the scales, make sure to mount them parallel & plumb - so that scales are not stressed as you move the table in X or Y.

    Sometimes you can let one of the end of the scales float - this way the scales can "self-adjust" .

    If I were to add a DRO to my mill _these days_, I'd seriously consider going with an Ebay 2 or 3-axis glass scale DRO kit. I had my share of issues with flaky 18" chinese scales. Loosing positioning during a job and having to re-establish 0 can be very annoying

    i mounted 2 chinese scales on my x3 in acryl casings. which i milled myself.
    to prevent chips onto the scales and to have electrical isolation between the mill and the scales.
    the scales have there positive battery voltage connected to ground. so if you connect the scales to a computer you will get ground problems.
    i use them for a long time now and in the beginning i also lost position but later i solved this by making better electrical ground for the scales. no problems since.
