The pack of carbide burrs, affordable and from Amazon, arrived. The first one I tried is tulip-shaped, the end was flat so I could go straight down on the spoke tip. No control, immediately gouged up the edge of the 10mm hole (dressed with a jeweler's file later). The second one was egg-shaped, and I could go in about 60 degrees from the vertical. Bracing with both hands, much better control. A few second per spoke, stopping frequently enough to check how much I was removing, did the job and I could move on to the next spoke. I wanted down to the surface of the nipple, I definitely removing a tiny bit of metal from each nipple but I want that at a minimum. Lots of fine metal dust, I expect some is in between the walls of the rim -- I need to see if I have one of those blow guns for the compressor, before I put on the fresh tape.
What I need to do is try to remember this topic, and
if when I next get a flat on this wheel, I should check tape condition and report back. My hopes are that the Kapton is not at fault, and by now most of my bikes have it.
Yikes -- that sounds like a massive amount of work, for 36 (or 72?) spokes. A creative solution, however!
