I turn the outside of the goblet bowl first leaving the bottom part thick. I don't turn the stem at all. Then I hollow the goblet. Then I go back and finish turning the bowl part. Then turn the stem and top side of the base. Then I use a parting tool and the toe of the skew to turn the base.

>Turned a few goblets in the past. Lost a few when the lathe was turned on, the goblet on its slender stem went out of round, and airborn it went within a few revolutions. Ended up first drilling out the majority of the "socket" with a forstner bit, finishing the inside, then start turning the outside. Made a stepped plug that fits the interior lip of the socket and held the top end of the goblet steady with the tail stock, but only with a light pressure. Too much tail stock pressure will flex the stem. Was able to finish the stem, then part off till about a 1/4" connection to the stub, sand the underside of the base with sand paper on a stick, then finish parting it off. Have made a couple this way with 5/16"dia x 6" stems.
Good luck !

>I hollow the bowl first then rough the outside next. Then I fine tune the inside then the outside of the bowl. At this point I sand and finish the bowl. I have a big cone live center the I move into the bowl I use paper towel so not to mar the finish. Now I start on the stem and base

>Once I start on the stem I don't stop the lathe until I'm finish. I've broken some thin stems just by turning on the lathe.

>Good point! Of course, with a VS one could slow down the lathe to a stop, and then start at the slowest speed and ramp up.

>Plus by the time you go away for a couple minutes, the thing is already a little out of round, putting more stress on the stem when you come back.
