I have some parts to examine. Think of a beer bottle. The dimensions are different, but the idea is the same. They are tubes about 8" long, 1" ID and 1.25" OD. One end is closed. They have been deformed and the wall may be uneven in thickness. The deformation may be as much as .25", and will be towards the closed end. The mouth will always be the narrow part. I want to find out where it deformed and how much the deformation is, and so I will be taking multiple measurements at different distances from the bottom.
Normally I would use telescoping gages to measure the ID. However I see a possible problem in getting a gage that is extended to 1.25" out of a 1.00" ID mouth. I could derive the ID from and OD and two wall thicknesses... but I don't know how to measure the wall thickness of a bottle.
It has to be a non-destructive test.
I suspect there might be a tool like a telescoping gage with a read out. If so, please tell me where I can find one, but unless they are less than $100 please give me some ideas with "the usual tools". I can't spend a few hundred bucks on this project.
Thanks
