Work continued on my hollow torus. I'd already removed the recess on the first side and had to figure out a method to remove it on the other side. On the first one I did I was able to expand my chuck into the center opening. This one the center opening is significantly smaller so that wasn't an option. I ended up using a combination of stretch wrap, painters tape, my vacuum chuck, and a padded cone on my live center. It wasn't the ideal solution but I did manage to get it done with minimal fuss. I probably used more stretch wrap and painters tape but I couldn't risk ruining the piece at this point.

After removing the recess and giving it a good sanding the piece was complete and ready for some finish.
