There are a bunch of different tap starters out there - I use a home made one
that I made on the mill one day
One of the slickest I've seen is a small disk about 3/4" thick, with a V groove
in the bottom. Centered in the V is a 1/2" or so hole. It then has a bunch of
inserts to fit the smaller tap sizes.
BTW, for the lurkers - taps from #4 and down all have the same "body" size
(Metalworking is one of my hobbies - I've got a lathe and mill in the basement,
and I hope to be buying a new better lathe about 8 weeks from now (want to get
an HLVH or better a CNC toolroom lathe))
