    Unfortunately many of us have neither a Brigeport mill in the garage or a friend who does. I once had both but, alas, no more.

    I find that a Barrett 50cal at 2000 yards makes just about the size hole that I need any closer than that has a tendency to obliterate the lens board.

    The small Dremel sanding drums, maybe 1/2 inch round? are good for final shapping and smoothing on a job like this.

    How much is a "bit" . Clamp and a hole saw if its more than a few mm. Otherwise a handfile for me too.

    There are rubbery sanding pieces that will slowly grind something down. I can't remember their part # and I'd have to feel one to know rather than see a photo. When I was restoring serial numbers at the crime lab, that's what we used to make the area a smooth surface before applying the acids. Anything else took it down too fast. We didn't get aluminum too often, but we did see it occasionally - same procedure.

    I would recommend a nibbling tool for the gross cutting, following up with either a dremel or a file for the final cleanup.

    Yea go forth with the file and do no evil.
    The hole saw, you're going to make an accurate center point and secure the board to it or it's really going to get messed up.

    You need the Dremel! The work station is pretty neat too, I put that off for a long time and now wonder why.

    I like the idea of using the Barrett.

    Most "machine shops" that cater to working with auto-repair shops for cylinder boring, etc... are generally more than willing to help someone out, at least from MY experience. Before I had money in my pocket, I scraped together my pennies to buy a 6-pack of Bud and made a swap for my "small projects" like boring/enlarging a lensboard(s).

    Usually they were more than willing, I'm sure its an "industry-wide practice/standard"
