It's all good. I was the person to bring up the use of the word "lathe" after the word "drilled" was used. In many cases, the person reading "drilled" in this context assumes a lathe... but many reading here on CD may not have enough machine shop experience.
Adding some detail on identifying the right tool or a reasonable equivalent is useful to many folks. I really like your idea of the potential for using a good drill press to drill a concentric hole.
Press-fitting long shafts is also tricky:
We used our heavy duty drill press to hold the shafts and raised the motor on the drill table into the pre-drilled shafts.
