Drill recess, insert chuck, screw chuck on to lathe, bring tailstock up to
secure, turn bottom and O.D., pull tailstock back and cut recess for
holding bottom while hollowing out the inside. Chuck up one more time and
clean up the bottom. It's that last chucking that gets a little funky.


Process actually goes drill existing oval hole on drillpress round for pin
chuck, mount and turn. Make bottom as simple or elaborate as desired,
reverse to a 4-jaw, turn interior.

Since I plan for my bottoms to suit the stable of jaws I have for my chucks,
I can do innies/outies, wide or narrow as I choose and get a true runner.
