What ATP told you is correct, but not complete. Most lathes also use a
Morse tapr in both the headstock and tailstock, so these could be used to
mount a Jacobs chuck on your lathe, if you have one. If, as you say, you
are a beginning metal worker, there could be a lathe in your future, so you
might consider keeping them.

If you really want to get rid of them, I'll pay your cost, plus your
shipping, plus whatever shipping would be to get them to me.

BTW, I am not a machinist--I am a woodturner. These same tapers are widely
used on wood lathes, if that info is of any use to you.
