I am trying to measure the countersink angle of countersunk holes in sheet metal panels. I was told this could be done by using ball gages, placing several balls in the countersink, measuring their height off the panel, then by "using trigonometry, just calculate the angle."
Has anyone done this before? If so can you provide better instructions than what is listed above and/or the proper trig formula to use? Is there a better/easier way to measure the countersink angle? (I was looking into handheld gages to do this but they approximately $1000 each and have to be made for a specific diameter hole.)
