3" hole Mild Steel 3/8" thick

[Sberry]

With a saw that had cut a dozen holes,,, if I was rested, in the mood, pilot hole drilled and a can of rapid tap handy could cut the 1 1/8 hole in 3/8 in 45 seconds with 3 drops per 1/8 ecery 15 seconds, no mess, gonna paint it.

It was from a previous build and used enamal on it but we had finished and painted and was so easy to sand and send to the booth we had running for another job to recolor it again and it was gonna be outside stored.
While I did cut a hole in under a minute it isnt a production time. But what it was,,, putting these hole in,,, in place, super accurate in an hour or so of dicking around with a battery drill and a 12$ bit. I could have come up with a clamping scheme for a mag drill if I had one but I was done before that would have even got underway and still got a bit I still use.
