This is mine, its the best thing since sliced bread.
I didn't buy it (now over $300) but a friend gave it to me because he didn't know what it was or how it was used.
BTW this is how I make my eccentrics, centre it up, move across the required amount, drill the hole. Once set up you could make any number that is required in a fraction of the time it takes in the four jaw. Just drop 'em in and drill.

I think things went wrong.
There should be a picture some where in thr post before.

Here is the finale project, I like it much better then the on you clamp on the spindle. I post the source from where I got the Print.

And here it is in use.

P.S. I will delete my previous post

Very nice piece of work.
What people don't realise is that this will also clock up very large diameters just by swapping the head round on the main two bars.
On my commercial unit there are two light springs on the fine adjustment, you can just make them out behind the words "ZERO-CENTER", I suppose they are there to prevent 'slop'.

Being the proud owner of a new rotary table prompted me to make an attempt at the indicator holder that you posted. Not having but very limited experience at operating a milling machine I spent most of the day making the parts and pieces of this wonderful instrument. About a hour in the morning should bring the end of the construction and frustration. I have to give a BIG thanks to the great directions that George Carlson wrote for the Building a Zeroit type indicator holder.
Until I unpacked and set up my little mini-mill, I had never seen a mill, or lathe operated. So Im totally self taught. Ive struggled through and made out pretty good with reading and trial and error, but not been totally satisfied.
The instructions the Mr. Carlson wrote brought into play many operations that I had read about but never had an opportunity to put into practice. I had a whole set of Edge Finders that I got when I bought the mill, but never realized their value until I used them today. His instructions described how to drill a small hole at the exact location from the edge of a piece. Something I was completely doing wrong before. Just using the dial/digital indicator to position the milling table was a big help.
Without going on and on, I learned a lot! Thanks for the great link and post.

And this is how I did it!
You want to put a thread on a part.
The compound is set over to 29°,
The dial on the compound is set to zero
The dial on the cross slide is set to 0 . All is ready to go.
You advance the compound by .010
You make the first pass and stop the lathe.
You retract the cross slide a turn or so and reverse the lathe.
For the second pass: You advance the compound by 005
You set the cross slide back to 0 .
What 0 Wait, did I reverse one turn or two. I have to remember!!!
That is where this part comes in. If you set it up as in the next picture
You will be able to go back to the once set zero but you can reverse the hand wheel
1, 2, 5 or umpteen times but go back to the starting zero with out counting.
Instant stop on zero. No counting. No looking.
Now you do the second pass.
And so on and so an.
Second picture:
Internal stop for when you have to turn multiple parts to the same length.
The front piece can be exchanged to fit the part in need.
In my case the length between shoulder and shoulder on a spindle is important.
