Hi Bill and Achim,This coaxial indicator looks very useful and has been added to my 'to do' list Do you find it more convenient to have the dial facing forward of facing upward? I am thinking about the view of the dial, when you swing it through 360 degrees.Mike
Well the beauty of a coax indicator is that the dial stays in one place and doesn't swing through 360 degrees.Bill
Hi Bill,thanks for the link to your drawings.It seems that I have downloaded the same set some time ago, I think via MadModder.During the last summer I have redrawn everything in Fusion 360 and I have started the making now.For me the information of the real shape and dimension of the rocker was a bit weak, so I have imported the picture into Fusion and the software has calculated everything by given the dimension of a known whole, 4 mm.Progress will be shown here.
Chris that are great for things like aligning the RT to the mill spindle. The only downside is they require a lot of headroom, but perfect for Bridgeport type mills.Bill
Bill's design looks like it needs less headroom than my SPI unit. So yeah it could work with the taller column. Bill
Looks good, It's really a buzz to see someone making something I designed Were the drawing ok, were you able to follow my description?BillP.s the pdf is on my google drive here:https://drive.google.com/file/d/0BwXDcXKx2KzlaUVrZ0l6QU4yaTA/view?usp=drivesdk

I have made it by a short piece of SS and a 3 mm titanium ball with M 1,6 already in it.The ball was available in in our local Piercing Studio, down the road.

An engineer will always find a way. Make sure it is a new and unused titanium ball, it's amazing what parts, some people have pierced Mike
Hi Mike, no worries, the ball and the bar has been washed in acetone before the assembly.

Acetone....a wise precaution. But it only stings if you were to use it for it's original intended purpose.
Where do you find the attachment "bars"? I have the SPI unit, but I'd like a bit wider selection of lengths.
