Alas, a drill press or milling machine works so much nicer than a lawnmower or hedge trimmer!
Far beyond my capabilities, so I'm forced to buy them. But I needed to do that only once, for I bought my lenses already mounted on a lens board.
I own the gear, but those don't make masterpieces. My everyday experience.
I buy an exact fit NEW quality USA Hole Saw whenever I need a new size and clamp the lens board DOWN in my drill press
I have a lot of hole saws
Or I use my old buddy who makes them full time
I did not do the second board.
I have a lathe, a milling machine, a drill press and fly cutters.
The person that made image number2 said he read about doing that way on this forum.

I've made nice lensboard holes with a drill, a jeweler's saw and finished with hand files and emery paper. The holes are perfectly round and there are no light leaks.
As nice as a cleanly milled hole made with a flycutter is, the hole only has to fit well and not leak light when the lens is mounted to fulfill its photographic purpose in life. There are lots of ways to make a hole...

when using the multi hole method, you have to leave a safe line so after drilling is done you can clean it to the actual dimension line with a file and emery cloth. i allow my safe line at least an 1/8" so there is enough meat to fine tune to the finish line.
yup, its not the tools... its who is using them.
The biggest hole I made for a lens was 6" for 790mm big lens
I thought I would never use that hole saw again
Wrong, used it 6 times, cost $20
I use Made in USA Milwaukee Hole Shooter 1/2" I must use the extra handle and hold on tight, it can break my wrist, if I am sloppy
