I suppose a lantern tool post "might" be able to hold a smaller scrap of
HSS, but to really get the most out of your HSS a tangential holder
might be the way to go.

I have a good selection of Armstrong and similar bit holders, obsolete 1960s-style tooling that matches my 1965 lathe. It's fine for carbon steel up through Grade 8 bolt hardness and puttering geezer productivity.
I've seen only a few tangential holders for sale, for formed threading bits and priced high. I made one to hold the shank of a broken carbide drill bit nearly upright to turn the race grooves in a stainless thrust bearing sized to fit pipe, for a solar array. My hands are still steady enough to grind a threading bit to closely fit the arrow gauge.
Today's rainy day project is turning closer fitting spacers and bushings for the ball bearings in the sawmill blade guide rollers.
