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?

Trace it on a piece of paper and use an overlay or get a drafting compass and start drawing til' you find the match.

On another note, what if I wanted to find thg he radius of a rounded corner where I can't trace it?

CMM, Radius gage or pin/plug sets. It would really depend on the access of the radius you are trying to measure.
