I am looking for some ideas on using a HF 1" digital dial indicator on the quill of my Bridgeport head. Has anyone done this ? If so, I would love to see how you did it.
thanks,
Brent

There is a little unit made by Indicol called a Deepol positive depth control that does exactly what you are talking about. It works great and they have been making them for at least 25 years or more.
You can find an image of one in the Travers tool catalog on page 803, they are $80. Model#DPOL order # 85-201-500. It can be installed on virtually any vertical mill in a few seconds.

I put an inexpensive 1" dial indicator on my Unimat spindle. It is great and I don't know how I ever lived without it. But the Unimat spindle has less than one inch of travel so it covers the full range.

There are some import 6 or 8 inch, digital depth gauges on the market. Check out E-Bay. They would cover the entire range of the spindle travel. And, unlike a caliper, the readout would be right side up. Should be about as accurate as a HF DI. Not much more expensive: $20 to @25 I think.

I don't understand how they can get $150 or more for a quill scale when calipers and depth gauges with the same or greater range are well under $50. OK, the ready made brackets are worth something, but still.....
