I just purchased a 3 scale DRO for my Enco 105 mill. My plan is to put the X scale on the back side of the table, the Y scale on the left side under the power feed, and the Z on the quill where I currently have a battery powered unit. Any mounting tips would be appreciated.

Thanks Gonzo
Are your scales magnetic? Your arrangement is what I will copy except I have an X movement limit switch on the front of my table so the X scale is going to have to be on the back. An idea is rattling around in my head about a remote vertical mount using pulleys and small cable which would leave me more travel space in the Y direction.

My mill is set up with Dro the same as Gonzo .I looked at fitting scale on tbe back side of table but it reduces travel and has the chance of being crushed if not Carefull.I have just ordered a x axis power feed also and plan on leaving the scale were it is on front side still and make a couple of brackets to hold a length aluminium t slot on front side of scale itself .i can use the aluminium t slot to hold and position the bump stops for the powerfeed and can still utilise same holes that the scale is mounted on just with some longer bolts and spacers can also mount the limit swtch for Powerfeed .not sure if you can picture what i mean

Thanks Nat
In addition to the bump stops on the front of my mill table are the adjustable stops for the power feed and occasionally they have to be loosened with an allen wrench and lightly bumped to release for moving. I will lose approximately 1" of travel and am in danger of damaging the scale as you have pointed out.
Three alternatives come to mind, the first is to make a guard to limit the table travel, the second is to see if I can follow your plan somehow and the third is to experiment with a light cable system to mount the X axis out of the way. O course I could abandon the power feed stops.

Yes
 
Hey Rockbreaker how did you go setting up your dro i have just finnished installing my dro and power feed as i described to you before .I did manage to fit it all in on the front side of my mill without loosing any travel on the axis .was a little bit tight but doable one good point is the dro scale is well protected now also

I like what you have done, is the scale in an aluminum channel? Also the power feed? After thinking about it I recall something about milling away sides of angle to mount these tools. With your permission I believe I will copy your method of mounting them. Otherwise I may do what is known in the mining industry; high grading it. Again I am impressed with your work. I haven't started on installing yet but due to your input and hopefully some warmer weather will get started.

P.S. Is the limit switch actuated with a "soft" touch?

Yes the limit switch does not take a lot of pressure to activate the angle that the dro scale is mounted on is approx 50 x50 mm just cut to length andctwo holes drilled for mounting and that leaves enought ledge to attach the chanel for the power feed stops the channel i used for this i brought at a home hardware dep store i think its channel for hanging running curtains from but does the job superbly .the eas no milling during any of the fit up only a bit of cutting and drilling easily done .the o ly extra thing u may have to do is make an extension for the hand wheel as i made new hand wheels a while back and made the drive slightly longer
