    Default DRO display mounts

    Gday All.
    Ive recently bought a DRO for my Bridgeport clone. It came with a couple of brackets and an arm to mount it to the machine but its not going to be suitable as it is.
    I have an idea if how I will mount it but thought Id ask if anyone else can post up some pics of how theirs are mounted to see if there are better ideas than mine (I'm sure there will be).
    Funnily enough, I had about 3 different types of old CRT TV wall mounts with assorted arms that I gave away about 12 months ago after having them in the shed for years. Using parts from them would have saved me a bit of work. bugger.

    Mine is hardly worth a picture. I used the arm that came with the DRO added an 18"ish long piece of angle iron as a "second arm" and bolted it on where the lifting eye goes. (I don't even think I've got around to painting it yet)

    Got a picture of what you have?

    That's pretty much what I have in mind. No picture atm as the display is still in the box.

    Thanks Dave
    No I didn't take that much notice.

    This is similar to what I have in mind.

    I used the supplied bracket, but shortened it and then made up a curved interface plate (my mill is a bit more shapely than Dave's). Key thing is that the pivot bolts need to be vertical (or near it) so the arm does not swing in or out when subject to vibration.

    I ditched the '1000 & 1 pieces' bracket kit for the reader heads and bent up some (one piece bracket) sheet metal to minimise the chance of something moving

    It looks like yours is on the LHS of the machine,or is it you have the display turned to better show the arm?

    Hi Peter,
    I have mounted a DRO on a Bridgeport clone by attaching the provided mounting base to doubler plate fitted on top of the electrical control box, this gives it rigidity and did not require drilling / tapping into the column. The supplied mounting arm had to be extended a bit to give it a working height and out of the chips. Seems to work ok so far. Alan.

    *don't know why the photos insist on being sideways*

    Thanks Alan.
    Since I converted mine to a VFD I dont have the original control box there anymore.
    I can see how it is a simple solution on yours though.
    I'll probably end up making another section for the arm on mine.

    No, it's on the left. The vertical head stows on the right of the machine when being used as a horizontal, so would obscure sight.

    I'm thinking of putting mine on the left as well, as I tend to work the machine more from that side than the other (except when down feeding the quill).
    When I was an apprentice I learnt on a big old "Made at BHP Newcastle under licence during the war" Cincinnati universal mill that was there. You operated it from the front or the LHS. Later, in another workshop there was a big old MAS or TOS universal which again was operated from the front or LHS
    So working from the RHS doesn't feel quite right to me.

    Default DRO source selector

    Don't know if anyone is interested, but in the latest MEW, 288, there is an article whereby you can run 2 sets of DRO's on the one screen, saving you some money. The scribe of the article runs a DRO on his lathe and his mill. There is some electronic wizardry required to do this project.

    My mill might look like it's flat but is actually tapered in, all my readout mounting kits come with 4x jack screws which are Allen head grub screws and 2x bolts to fasten it in the center.
    I agree to set it up level or it will follow gravity.

    When I installed my first DRO on a mill back in 2007, the scales came with no mounting kit.
    Way over kill back then but wanting to do it right and made them out of 6mm steel shaped and welded together.
    Then I got the replacement mill and the brackets never even came close to fitting the castings, typical of Chinese machinery.
    I still have those heavy brackets lol.

    I have thought for a long time of throwing it all to the left like my lathe is.
    Though you won't have that problem, I find it difficult seeing the quill reading as my arm is in the way.
    Would be a lot different for me as I've grown to know it to be on the right.

    I'm thinking of making a double jointed, double arm that is long enough that it can be brought forward and the display turned so that it can still be seen when operating from the RHS. I really haven't had a good look at it yet. I don't want to start that project until I get my coolant system done as I know if I do, I'll end up with both of them unfinished for some time.
    Now I wish I hadn't given the TV mounts away as a lot of the work was already done with them.
    So it goes
