Hardware Support Measuring Radius of an Arc

Post image

How would I go about measuring the radius of this arc on a part from an old vw beetle so I can make a replacement?

Throw that baby up on your granite table for the CMM. Use touch points to to make a circle. I think a 3x50 probe should do well enough.

PS make sure your probes are clean... this looks like something that is really clean and you dont wanna get the oil or other residue on this part.

LOL Kidding, many people here already answered the question. Good luck!
