To find the bowl in a log look for grain, burl, spacing and special distortions.
Cut out the part of the log you have chosen.
Slice log in half to make two bowls.
Cut out the bowl blank from the half log with a bandsaw or chainsaw. Find the right spot in the half log to get the most grain activity.
Attach faceplate where the inside of the bowl will be.
Mount the bowl blank on the lathe and shape the outside of the bowl first. Lathe turns at about 500 rpm. Cut a tenon at the bottom of the bowl to re-chuck the bowl to cut out inside. This is when you begin to see what the bowl will look like.
Re-chuck. Attach chuck to tenon. Then attach back to the lathe and carve out inside of bowl being careful not to harm the edges of the bowl while applying the cutting gouge at 500 rpm.
Attach and re-chuck the bowl again to shape and clean up the foot and bottom of the bowl.
Sand, sand and re-sand while filling any unwanted cracks and holes. Start at 40 grit then move to 60, 100, 150, 220, 320, 400, 1,000, 3,000 and 10,000 grits.
Finish. There are many options from nothing, to mineral oil to a hard finish..
