This must be Art? or Boom boom mancini

[John Hicks]

One of my attempts at an emerging hollow form out of a live edge punky maple burl. Boom said the wood at 1000 rpm when I cut the bottom too thin and it popped the whole piece in chunks. My lesson? keep wasting my time with punky maple burl of course!

Art and a message. Stay out of the line of fire!

glad you were not hurt.
I turn my face grain hollow forms using a faceplate. I turn endgrain hollow forms with a tenon or a faceplate.
I urge you to use a faceplate for your next attempt.

in my experience (and maybe yours ) a recess is flirting with disaster.
While way weaker than using a tenon or faceplate it makes it difficult to judge the bottom thickness.

bottom thickness is easy to measure with calipers, lazer, or video with a tenon or faceplate.
Nearly impossible with a recess as you can’t measure where the corner of the recess is.

This is a video clip from a hollow form demo that shows mounting the faceplate.
