Currently we use a digital height-guage with a DTI. I zero at one part of the blade, than take multiple measurements along the curve... then I plot those numbers.
I want to zero at the same point, move along the part and take those same readings electronically and display them on a small screen.
First step is figuring out how to measure the part. I'll post a sketch this evening or late tomorrow.
Once I get that figured out and built I will mount the whole thing on an old inkjet printer mechanism, then figure out how to automate it.
First we measure... then we automate!
