Best method for drilling 5 evenly spaced holes. In a circle.

[airrj1]

I am working on my wheel adaptors for my Chevelle and I have a question for you machinist/smart people.

I have the adaptor sized correctly, now I need to drill and spot face all of the holes for the adaptor. I have two possible methods to do this. First my mill has a digital read out and I could zero the DRO on the center of the adaptor and then use the X-Y coordinates to determine the proper spacing of the holes. Or secondly I have a rotary table for the mill. I could center on the adaptor again and then move out to the C/L of the bolt circle and drill my 5 holes every 72 degrees of rotation.

Any thoughts on this? I would hope if done correctly they should come out with the same results. Just checking for some suggestions.



Thanks.
