Since you are trying to fair out an inside curve, take a couple of
pages out of the boat building community where fairing is a common
practice.

1) Make a couple of profiles from 1/4" hardboard or 1/8" aluminum, if
you can find it and machine it.

2) Saw the blanks as close as possible on the band saw.

3) Knock off the high spots with a 4" right angle grinder equipped
with a rubber sanding pad and 24 grit discs. Use profiles to check
your progress. (Aluminum will leave black marks on the high spots)

4) When close, say about 1/16", switch to a 2" dia x 2" lg, 40 grit
flap wheel. You can use an electric drill but a low cost air drill is
my favorite.

5) When you are within about 1/32", switch to a rubber block and 100
grit to finish.

Using the above, I watched a guy fair out airplane propeller blades to
within 0.001".

I hired him to fair out my boat.

Nobody says it id easy, but it works.
