View Full Version : Digital Readout for an old rockwell mill?

01-25-2012, 09:43 PM
I have a 21-100 rockwell mill built in 1965 and I think I would like to add a DRO. I really only need the two horizontal axis, but 3 axis would be fine. The table travel is:

Longitudinal: 16.5"
traverse: 6.75"
vertical: 16.5"

I do not necessarily need to be able to calculate bolt patterns or do any other math with the DRO. I am mostly looking for postion and the ability to tare to zero at a position. I would like +/-0.0005" but would consider +/-0.001"

Any suggestions?

I would recommend the guy on ebay selling Sino, he has 2 axis posted for $450 and $550 posted for a 3 axis.
If you look at his feed back he has loads of happy customers and I have never heard a bad word about him.
Postage is usually 7-9 days to you door and if you have a problem he will fix it right.
