Started installing the DRO on my Bridgeport
Tons of people have done it. I have the Shooting Star 2 axis outfit on
my old vertical mill and love it. I know what you are talking about, worrying that you won't do any permanent damage. I suggest taking the time to make simple jigs to assure that holes get drilled in the right place. If you have to tap some of them, get some brand new high quality taps. Maybe you need to spot face/file/grind some of the locations where holes need to be drilled. Don't work on it when you are tired, or after too many beers. Don't "Expect" that you will make mistakes. That may be just a self-fullfiling prophecy. Let your gut tell you to stop, think, get more info or skill, as necessary.

I believe that both X and Z, are considerably simplier than Y due to the fact that for X and Y, the surfaces that move along each other are parallel, but for Y they are perpendicular. This DRO seems to be nicely made, actually, with splash guards, strain reliefs, and other niceties. My expectation is that I will make some mistakes, but I hope not to break anything permanently. Is there anyone else who installed their own DRO on the mill? |

When I bought the Anilam DRO for my lathe, supposedly with the mounting kit for my exact model lathe, it still required some fitting and parts-making to the saddle. The "instructions" were more of a general description of the mounting principles, rather than step-by-step application to the machine I actually had. |

Anyone anticipating a DRO installation should have been/be searching eBay
for installation kits/brackets. When I was looking into DROs, there were numerous sellers offering complete new install kits for knee or vertical mills, and lathes, some for as little as $12, IIRC. When you can get the heavy duty brackets already drilled and tapped with good quality mounting hardware, shims, and even the printed layout dimensions for the mounting holes, the task is greatly simplified. Searching the major DRO brand names may turn up some similar kits. Then there's the option of making your own and improvising the install, which may end up costing a lot, for a setup that isn't accurate.

This Uniq kit, actually, comes with quite a few brackets. I tried putting the X axis brackets together, and I think that there is enough of these mounting things. These should fit Bridgeport mills, I think. -- Due to extreme spam originating from Google Groups, and their inattention to spammers, I and many others block all articles originating from Google Groups.

Somewhere, in your archives, are the pix I sent you of the install I did with the same unit on the 2-axis version. Throw the instructions out and just "common sense" it. Make sure nothing binds. For the "Y" axis, I used the bracket stuff with the unit but had to cut some pieces. For the "X" axis, I made a piece out of a 1/4" x 1.5" x 6" with a pocket milled in it for the encoder. That way it has just the right thickness. I used 1/4-20s for everything. Once I had a plan, it only took a couple of hours. Do you want me to see if I still have the pix or shoot new ones? |

Tom, with great regret. I must say that unfortunately, the message is not in any archives, I have no idea what happened. I think that I have made a good Y axis mounting, as of now. -- Due to extreme spam originating from Google Groups, and their inattention to spammers, I and many others block all articles originating from Google Groups.
