Woodturning 600 pound Maple speaker cone, part 1 - Machine industry and woodworking


A big-leaf maple burl was wood-turned on a VB36 lathe to make a speaker cone for a home music system. The burl started at 600 pounds and was shaped to form a cone about 30" long and 28" at the mouth. The inner curve of the cone followed a parabolic shape to a 2" opening. Part of the challenge was cutting through stones that were imbedded as the tree grew. I hope you enjoy watching something nature grew metamorphose into a pleasant and useful shape.
I apologize for the audio being out of synchronization with the video; it shifted somehow during the upload to YouTube...
