Looks intriguing. I built sort of the same thing but with 3 teeth. I took a 1 1/4 x 8 Nut and drilled 3 holes in it. Then I stuck some sharpened metal dowels in. I use it for turning bowls when I start them between centers with the bark side toward the headstock. Works fairly well but I made my spikes too long.
