Removing elevator bolts- this worked for me
Working on the Bambi II, I got a medium sized hole saw and my drill. I drilled a hole around each elevator bolt head (with the pilot bit off center) about 1/4" deep. Then I chiseled out the circle of wood. This gave me greater access to the elevator bolt heads. I locked a vise grip on each one and wiggled it until it broke off, then tapped the remaining threads into the belly pan. We'll find those later. This procedure worked quite well.
