Roughing a Bowl, Video 4: Knocking off the corners



Once the blanks are marked I like to cut off the corners before mounting on the lathe. First of all it tends to give a better balance without all the extra wood. There is also a chance to cut off any extra bits and pieces that might otherwise give balance problems. Second it allows for a bigger bowl to be placed on the lathe. The diagonal of the blank is about 1 1/2 times as long as the diameter of the blank. Actually about 1.4 times for all you fussy mathematician types. Getting as much of the extra wood off the corners as possible allows me to turn a 16" bowl on my 16" lathe instead of only a 10" to 11". Finally, the chainsaw is a bit faster than the lathe at the wood removal.
