I may have posted this already, and this may be an "Oh, yeah, we all know that thing" but if I want to quickly mark a circle on a tube that's close to perfectly perpendicular to the tube (e.g. for precise alignment of centering rings)
- Mark the spot on the tube
-Get some high-quality masking tape (frogtape, 3m blue, etc - something you can repeatedly pick up and put down without it losing stickiness)
-Tear off a bit more than one circumference
-Put the middle of the tape at the spot, trying to make the tape perpendicular to the tube.
-Lay down half of the tape.
-Carefully wrap the rest of the tape. If the tape wraps perfectly over itself, great, you're done. If it doesn't, pull most of it off, adjust the end of the tape slightly up or down, and rewrap until the tape aligns perfectly with itself.
-Mark with pen along the edge of the tape.
