626 Mill Y Axis Stops

[doubleboost]

Hi
Lads
I Have wanted stops on my Y axis for some time
Rob Wilson kindly donated the T slotted stop casting from his 626
(be about the last thing you would want on a CNC)
First job was to remove the Y axis DRO scale
(this was never mounted properly as i wanted stops fitting)

Notice how long it is
The dovetail was mounted and some decent brackets made up




The scale was cut to length , i have cut these before and got away with it.
Not this time the glass came out of its mounting groove




I had a hell of a job getting it back in but worse was to come
The read head is a spring loaded job with a ball bearing running on one side of the glass , and some electronic miricle running against the thin band of tape on the other side
(sorry no pictures)
To cut a long story short i dropped the ball , after a couple of hours scratching about in the swarf i found it.
All back together now and working fine
John
