You know about the "Shaper Origin Handheld CNC router"?

https://www.shapertools.com/en-us/

One sticks a coded tape on the workpiece, a camera uses this to locate the
cutter head in space. One moves the router frame, by hand, along the path given
on the screen. All the inaccuracies and squiggles are adjusted for, as the
cutter head is moved within the frame by servos. Get too far away from the
programmed path and the cutter goes up...

There's also some sort of speedometer to show the feed rate (which you
programmed along with the shape).

It conceived for things which can't be put in fixed CNC machines, like floors.

Horrendously expensive ($2500), but they offer them to maker labs at cost to get
the feedback, and to profit by what the geeks think of as they play.

Alternatively: a sharp chisel, cut out a diamond shape with a mild taper, fit
plane-tapered plug by hand. (I know people that can pull that off and make it
look easy. One trick is to compress the plug lightly with hammer taps, so it
swells into place at the surface, once the glue moistens the wood...)
