As yet I have not turned or drilled/bored any stummels, but in preparation I want to practice on some scrap wood that I have, like black walnut, so as to get the "feel" of it.
My metal cutting lathe (12" swing over bed, 7" over table, 20" between centres) runs at the following speeds: 160, 250, 400, 630, 1000, 1600 rpm.
Based on your experience I would like to ask the following questions.
What is the optimal speed for drilling/boring the: (a) Tobacco chamber; (b) Mortise; (c) Shank draft hole; (d) Stem draft hole;
Also, what is the optimal speed for turning the: (1) Bowl; (2) Shank; (3) Tenon?
I included the stem questions since it's easier just to lump all the drilling/turning questions together.
Thanks,
Frank.

My general rule of thumb:
Drill as slowly as you can, and
Turn as fast as you can.

I guess 1600 rpm is as fast as I will be able to turn.
Is 160 rpm a bit too slow for drilling/boring?
Frank.
P.S. Tyler, hope you don't mind that I downloaded your pipe making videos from your site. If it's OK, I'd like to burn them to disc for quick reference when needed. Yep, I'm still a at this.
P.P.S. Nice shots of the back of your head whilst peering into the tobacco chamber. (chuckle)

Downloading the videos is fine with me. I just want people to be able to use them.
As for drilling at 160 rpm, I don't know if that is too slow. My lathe won't go that slow. I doubt it is. That's where I'd start if I was you, and if you find it isn't working well, step it up.

I'm with the others go as slowly as possible when drilling. If you go too fast when drilling stems you'll melt the material and the interior of the stem have a rough texture.

160 RPM is probably about perfect for drilling. The slowest I can get is 350 RPM, and even that is too fast for my comfort. However, it will have to do until I can scrape up the scratch for a size extra large metal lathe.
For turning, I use whatever the harmonics of the lathe/table/block tell me to use. Some blocks will set the lathe vibrating like there's no tomorrow at 1800 RPM, but will be steady as a rock at 1200. Others are the exact opposite. However, I've found that I dislike turning above 1800 unless absolutely necessary - like if 1200 and 1800 vibrate too badly.
Good to see you coming around Tyler!
