Mike,
You and I had the same idea. I haven't checked Travers yet, but Rutland - which usually has *anything* I need - has a hugh gap right around that .5469 reamer. The next size down was .5370 and then 5315. He'll probably have to settle for having the .5469 reamer ground down to size.

You need to find somebody with a tool and cutter grinder who knows how
to use it. You might look for a tool cutter sharpening service in your area.
They can make that into the size reamer you need.
You might can buy a proper sized one from MSC, Travers, or one of the
other industrial supply houses.
Do not use the flapper wheel, it'll be anything BUT straight. Mike C.
