Sizing for a DRO (slides)?

[ScrapMetal]

Now that I have a mill, and I'm close to getting power to it, I need to look at find a replacement for the DRO system that is currently on it. The box itself is DOA and without a circuit diagram it would take me a loooong time to get it back working if even possible. I don't know the condition of the slides, of course, as the box is dead. Even if they are "good" I don't know if they would be compatible with a new box.

With that being said, I am looking to maybe get a whole new DRO setup. I believe these to be the specs on my mill (I'll measure it before I order anything.):




So, 10" x 48" table but longitudinal travel is 34" on a 46" table???

Cross is 14" and vertical knee is 16.5".

Now, if I am looking for a 3-axis system how is that sized out? Do my slides need to be 34"+? for ends/mounting or what?

Basically, how do I figure the right sizes to order?

Thanks much,
