| Digital Caliper with custom plates? |
| << < (5/5) |
| q12:
I read everything you wrote guys. I am thinking on a solution. Here I measured as close as I could possible with my Mechanical Caliper, the copper elements. The copper elements are shown on my end digital caliper. Help from a magnifying glass + light = higher resolution reading. Everything is measured. Even the obvious sizes like that 0.730 I just gather data for now. I hope i can use it. I am aware how small everything is. The problem I was confronting with is (surprisingly) not these tiny elements, but the support that they should stay. I realized I don't have too many options to fabricate it as long as I want. I could, but I was thinking on alternatives. And it hit me. I had a brilliant idea while doing all this measurements: - What if I continue with another (same) caliper tail to the existing one? And I actually purchased already from ebay another best cheap one i found. 3$ gone from my life. Off. The plan is to unite 2 (same) tails and make the thing longer. "Estimated delivery Dec 13, 2018 - Jan 24, 2019" - i'll have to wait for this possible solution to arrive. In the mean time, I will search for a solution with what i have already and what can be done. :box: Here is the proof i'm serious about it: |

The expansion coefficient of your substrate is a significant obstacle. However, I have little doubt that you have the ability to get the fit between the scale pieces to make it work. But you may run into a snag with the absolute position determination. Short of comparing the pattern of a 12" scale to a 6" scale the only way to find out is to try. As has been commented, buying a longer scale is cheaper unless your time is free and your money is *very* limited. But this is a fine example of why I like this forum so much. It's a bunch of thoroughly demented, but very smart and mostly very pleasant people. There is a steady stream of obnoxious, rude and ignorant fools who imagine themselves the smartest person in the world that wander through, but I've observed that they don't last long. Cheers! I look forward to seeing how things work out. |
