Well, today I tried my first hollowing of a vase form, and succeeded in hollowing to 7” deep on a lovely Spalted Birch piece, with a Western Red Cedar collar. Down toward the bottom, about 3/4 of the way down, I managed to cut through the side. After a few choice words, I decided to part it off and invert it, using the top collar for an elevated base and cutting a red cedar plug to fill in the hole. It came out 3” x 3”. I haven’t finished the inside yet, but this is the result. Back to the spalted birch tomorrow to try again!
