Dro Z Axis - Quill Or Head?

I will toss in my Noob observation based on about a month of using my G0759 that has the DRO on the head and a simple LCD DRO on the quill.

I move the head almost exclusively so I can use the larger brighter and easier for my old eyes to see. The LCD on the quill is not very easy to read because it is smaller and LCD and not back lit.

Good point and I had thought about that because my eyes are not what they used to be.
 
Okay DZ talked me into re-thinking my decision to return the DRO...I stared at the mill for a couple hours and I think the X and Y will be fairly straight forward now. X will mount on the rear of the table, I will give up some Y axis work cube but I won't be often milling with the table that far back up against the column anyway. That leaves the front uncluttered and free for the power feed and stops. I'm going to use those two huge lifting bolt holes on the base for Y, mount some aluminum bar there for the scale.

The Z scale will be on the quill and I'm going to try to include an improved depth stop while I'm at it. I have no room on either the left or right side of the head so it will have to be down the center of the head. Its going to require some engineering and money, either the scale or read head will probably have to ride on some sort of linear rail. Thanks to DZ for the pics he posted in his thread there's some good ideas there. I think I'm going to clean up the quill bracket thingy on my lathe as he did also.
 
I installed the DRO on my Grizzly G0755 mill much like Darkzero did. I put the Z axis on the head in case I ever did need it, and put a magnetic scale with a larger remote readout for my old eyes, on the quill.

Not to get too far off topic but do you have any pictures of the install on your G0755?
 
Yes, its a depth stop by design but is rather crude. You turn the thumb screw at the bottom and that cast iron piece on the threaded rod moves up/down and stops against the casting. The rod is wobbly and of course there is no quick adjustment like on many depth stops. The center of that stop T pokes through the faceplate and the arrow indicator screws on there, there is an inch scale printed on the face plate.

As for the DRO...I'll PM you.
My version of xx45 clone has two micro switches mounted on the holes visible on the photo.When the lower
one is activated the motor reverses.When the quill retracts the motor reverses again to the original sense.
The function can be selected by a selector on the control panel.S
upposedly is for power threading in through
holes.The piece on the threaded rod is only good for activating the micros.It is totally inadequate,to my
opinion,to function as a stop.

I hit the local metal supplier today for some aluminum bar for this project. DZ forced me to buy a bunch of steel cut offs with his over the top quality depth stop. Dang DZ that Morton Machine Works quill stop is not cheap, looks like I can get it on sale though at Enco for about $37.

I got mine from Grizzly. They had them for just over $30 & I added it to an order I needed to place. Grizzly also has some other less expensive alternatives if the different thread pitch & lack of a scale doesn't matter.

I do have lot's of pictures, but being new to this forum, I have to have three posts to be able to post them. This may be my third, I'll check when I get a chance. I also got my G0709 lathe last Thursday and I'm putting a DRO on it too. I'll document that process with pics too.

Yup, DZ is costing me more money again... Received my depth stop late last week. :cool:
