I completed my DRO installation and check out today. Will go back and tidy things up later. Most difficult part was drilling and tapping the base under the gearbox for the 24" scale left end. I wanted to drill thru the web and not have to tap a blind hole is the reason I did not go lower. Z mount is adjustabe for height by means of a split clamp on the bottom. I can have a full 6" range no matter the height of the head. Cross slide was pretty easy with no problems. In order to mount the 24" X scale the only place I could put it was under the carriage. It is out of the way and I have a plexiglass cover under construction for it. I am using a YADRO system for the readout. I can switch between lathe and mill just by a few key strokes. I can also swing the PC around and hook it back up to my big mill just by changing 3 DIN plugs. I have tested all the axis with a DTI and they are dead on. If anyone has any concern about the magnets slipping or moving just don't have a finger in the way when you place it..The only way to remove one is with a screwdriver for a pry bar. Now I can get back to work on my steam engine!!! Julian G.
