Time to finish finishing this bowl.
Before parting off make sure the inside of the bowl is finished to your satisfaction. Once parted from the waste block re-mounting to work on the inside gets difficult.
Parting the bowl from the waste block is really quite simple. Run a parting tool between the waste block and bottom of the bowl but don’t part all the way off. You don’t want the bowl popping off the lathe at speed and risk damaging all your hard work. I left about 1 1/2 inches of material. Stop the lathe and gently pry the bowl from the waste block using your parting tool. The weak paper glue joint should just pop right off. If it doesn’t you can use a sharp hand saw to cut away the glue joint.
With bowl separated we can work on the bottom portion. I use a set of jumbo jaws for my chuck. Another option is to use a Jam Chuck, or shop made cole Jaws. I have the chuck and the Jumbo Jaws, so I’m using them.
Remove the rest of the paper joint and true up the bottom.
You can see that I turned a relief in the bottom of the bowl. Bottom treatment is turner’s choice. I wanted this bowl to sit flat. Some people turn a foot, some people leave it completely flat. Do whatever you want. Then prepare to apply the finish.
Don’t forget to sign your work. I like to date it (Year/Month, rarely do I make a bowl in a single day). I also add any specific instructions.
Apply the finish to the bottom.
Done, not a bad result from a cutoff that was just sitting around.
Once the finish cures, this becomes my Ice Cream Bowl.
