(1) How did you measure the outside diameter? And, was the stove pipe perfectly round?
(2) How did you make sure that the tape was wrapped straight around the pipe with no slant?
(3) How did you measure the length of the tape that you wrapped, before or after you wrapped it?
Just curious.
Rip to width. Plane to thickness. Cut to length. Join.

Old welders trick.
Use paper that's heavy and wide enough not to flex.
Wrap the pipe and mark where it starts to overlap.
Lay flat and then you can easily measure total length and subdivide as needed.
Use wide enough piece you can measure a square the length of the pipe diameter, fold corner to corner both ways, then cut along the top two creases and you can lay out a 45 degree joint.
