Get a spade drill bit and regrind it to the taper you would like for the
hole. Then drill the hole with the modified drill bit in a chuck in the
tailstock.

I am a high school wood working/turning teacher and have some students
interested in turning candleholders. Other than trial and error are there
any
suggestions on how I can get a novice to make the tapered hole the correct
size
so the candle sits straight?
