I cut the gears on my CNC router, With BobCad. The first attempts I used Red Oak and cut pie shapes and laminated them so the end grain of the wood was into the teeth of the gear but I didn't wait a year to cut the gears and found out why, SNAP! But I thought I'd try. I ended up using Baltic Burch Plywood which worked real good.
This one cracked, See the pie shapes, to bad it didn't work it came out real pretty.
Thanks Jerry
I don't what Tags are or mean? Can someone fill me in?
