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

I admire your courage cutting glass scales. So, apparently,it can be done. Thumbsup

I was going to say, Hey I'm not the only one with a "way too long" Y axis scale.

Maybe this is the time for me to " 'speriment " with my Mitutoyo scales, the DRO is acting up and it may be at it's end (sorry Claude!).

Oh, I'm still looking for the "dovetail" that was mounted??

Sorry John, I thought dovetails were angled, I thought it looked like a "T" slot.

I have to admit to eyeballing the engine in the back corner as well.

You are a determined soul John. And cool under pressure at that. If a scale flew apart on me like that, there probably wouldn't have been anything left to put together after I tied it into knot! Bash
