I’ve fairly new to machining ( less than two years experience)

I really struggle with using dial indicators on round parts ( finding the OD, ID of a circle )

Was wondering if anybody had any tips or videos I could maybe use to improve my ability to use it!
Thanks again
 
It’s more finding the x0. Y0. That I struggle with when doing bolt hole patterns , counter bore etc.

Just practice. Bring your indicator down to just above the part, and sweep it around. Make your big adjustments. Then bring it down, do X first. Zero the dial on the first side, rotate 180 degrees and read the dial. Move X axis 1/2 the amount. This is center X. Rotate the spindle 90 degrees. Now adjust Y axis until the indicator reads the same number. That should be center Y.

Now sweep 360 degrees and check all around the circle. You should be within .001".
