My first two attempts to turn an "emerging bowl" ended with tape failure. I turned the half sphere and separated the blocks. I mounted the block with tape and supported the half sphere with three wedges on tape. I used clamps and tail stock pressure to "set" the tape. In the first attempt, I had stopped to check the depth. Depth was perfect, all I needed was to clean the little nib in the bottom. Turned the lathe on and before I could pick up the tool, I noticed a "ghost"; instantly the block flew off. There was no catch. I'm not sure where that role of tape came from so "maybe the tape is bad" I thought.
On the second one I used a newer role of "turner's tape" and went through the same steps but failure happened shortly after I started hollowing the bowl at a slower speed.
The face plate is Baltic Birch and very clean. Okay, I am ready to hear from you, what did I do wrong?
