Mini-Mill: Adding An X Axis DRO

Adding an X axis DRO on the mini-mill.
People have put their X axis DRO in various positions, on the back is one of them, but since I don't have the display unit built yet, I need to be able to actually see the readout.  I looked to see where I could put it, and of course, the front was the only other option.  I picked a 12 inch horizontal unit for the X axis.

 
The whole scale can be mounted with two pieces of aluminum angle.  This is about 1 1/2 inch by 1/8 inch thick aluminum angle, so it's moderately sturdy.  I used the existing mill bolts that hold on the end plates on the table.  They're both M6-1.0, and I bought plenty of them.
I used the existing pointer hole, also tapped for M6-1.0, to mount the readout.  This time, I could use the existing bracket, although there was not enough space for it.  I had to mill down a part of the bracket to enable it to fit, but this was much easier than making a bracket.
Holding the scale in place with a clamp allows me to see just what will fit and what will not, and to check clearances.  The back side is trimmed down a little to clear the casting, and the right side is trimmed down to just clear the bracket.  I also rounded the corners a bit later.
This only has to get close, since there's a bit of slop in the design.  The bracket has not been cleaned up yet, but you can see that it does clear the casting.  It looks better once it got cleaned up, really.
The scale mounts the same way as the Z axis scale, so all I need to do is to tap the bracket for an M5-0.8 screw, the same sort used on the Z axis.  What you don't see is the the mounting hole is slotted so I can adjust the front/back distance of the scale.  The existing scale bracket allows me to do an up/down adjust, and the left/right only has to get close.
Here's the overall view of the right side.  There's enough space between the gib mounting screw and the scale that I'm ok so far.  If I decide to get picky about it, a piece of rod suitably tapped will be a good extender.  I might want to do that on the Z axis as well.

 
Mounting the scale on the left side is done just exactly the same way.  I can adjust each scale position up and down, and in and out, so that lets me get the scale adjusted within a few thousandths.
Here's the overall picture.  You will notice that the workbench is messier than it was before, just wait until the project is finished. 
So here we are, I've managed to install the X and Z axis readouts. The connector for the X axis readout might be in the way a bit, but I'm hoping that they are right angle, it would be nice.  Low profile will also help.  One reason that the scale is so far out is that the mill fixtures have an alignment tab that fits to the front of the table.  Everything is aligned from there, but the lip takes a bit of space, and the scale has to allow for that.

Next will be the Y axis
