If your not worried about a hole through the middle a hole saw would work
Use a router and trammel bar to make the initial 200mm template, then use a router and bearing guided cutter to make future copies - using double sided tape to stick the template to the workpiece.

Coping saw. You can get a fairly good one for about £12 brand new (mine's by Sandvik, never had a problem with it). Buy a packet of spare blades at the same time - the Eclipse ones are good.
To tidy up after cutting, coarse sandpaper wrapped round a small wooden block will do, but a rasp or coarse file will be quicker. Then finish with fine sandpaper.

A 200mm. hole saw? Now that I'd like to see!
I'd also like to see a windchime with 200 x 25 mm discs!

I use a 225mm holesaw for drilling vents through timber framing on apartment blocks for balancing vents. I suspect that the 200mm x 20mm discs are to hang the chimes on!

Sorry was eating lunch at work at the time and obviously didn't read properly thought it said 20mm a 200 saw would be a beast I bet
Bearing in mind that this is the Handtools section, a coping saw followed by rasps and sandpaper would be the least tiring option. But you could also use an ordinary saw to cut a square, cut off the corners, leaving an octagon, then use a good sharp chisel to pare off the remaining corners. Work downwards onto a piece of scrap on the bench. Keep on cutting until your cuts are tangents to the circle required.
A cooper would have used a bowsaw followed by a drawknife to make the circular tops and bottoms for barrels, which is a similar sort of job, but generally on a larger scale.

absolutely - the fastest hand-tool way I imagine would be bowsaw (accurate and close to the line, saving a lot of effort after), then drawknife or maybe rasps etc.
But if you are in production and making numbers of these, you must surely have a bandsaw? Any smaller bench-top would knock these out with a suitable simple jig in about a minute each (from rough oversize blanks, any reasonable shape).
If you preferred the electric way, a disc sander to finish the edges (jig again to keep centre). It isn't the kind of piece where hand-tool skills are going to show up in the end piece (unless you mess it up :lol: ). The electric way does make dust and noise of course.

How about using a lathe? I make round flat chopping boards on mine and the diameter is anything you want it to be.
