For mine, I used a 1/4" round carbide bit. Was a scriber point in a past life, but the tip had snapped off. I made it a rounded point on the grinder at work.
To get it exactly on center, I mounted the turning attachment on the lathe, and drilled it with an undersized bit, then reamed. It's as dead on center as I can possibly get it.

Full of ideas, but slow to produce parts
