Great work Bill. I've got a trade bought Coax and its a bit on the long side for my machine I had to make a special collet to get it fitted, but this design being shorter would be a lot more convenient. :clap: :clap: :clap: :clap: :clap: :thumbup: :thumbup: :thumbup: :thumbup: :thumbup: Stew |

Thanks Guys :D Rob, I like your bar bell idea - It'd save me having to rig up a ball turner. bp, Another good idea - The ends of my other indicators have a ball in a pocket as you suggest. Bogs, I like the mandrel idea. I don't need to face all the way to the centre, so I can set the thing between centres. The aim of a MkII version would be simpler/easier construction and/or more accuracy. I have yet to test the centring with another DTI but judging only by the feel of the handles it no better than +/- 1 or 2 thou"; There's about a 3:1 loss between the probe/rocker and the DTI so 1 thou" on the indicator could be 3 at the work piece.

Bill, I know this depends on the length of the bar, but in the configuration shown what sort of displacement of the meter do you get for say 1 thou of error? (Nice job btw!) |

(Nice job btw!) --- End quote --- ATM 10thou" of displacement caused and indicated 3 thou on the DTI (which would be doubled as run-out). I suppose a quick improvement would be to swap the cheap DTI for a tenths indicator. |
