Good points about trying to ream out the bore in the STEERER.
Reamers are designed to remove a small amount of material to accurately size a hole that is close to the finished diameter.
The maximum recommended amount of material for reaming steel is 2% to 3% of the reamer diameter.
21.1mm = .830" x 2% = .014" = .007" per side - the depth of cut
21.1mm = .830" x 3% = .025" = .012" per side - the depth of cut
Removing 1.1mm of material (.043" or .022" per side) from the bore can be done taking multiple passes with an adjustable reamer but it can be a lot of work.
On another topic and suggestion:
Using standardized terms for bicycle parts and components makes it easier for folks to understand descriptions, especially for the many BF members who are located outside the US and English isn't their native tongue.
The HEAD TUBE is the tube at the front of the main triangle where the headset mounts.
The tube attached to the fork crown that the stem fits into or onto is called the STEERER.
The UK and the US... Two peoples divided by a common language!
