I haven't cut any yet, plan to do some. I always pictured it as cutting the blanks at a 45 and putting it in a divider and cutting the teeth. A friend cut some for his engine and they didn't look quite right, the teeth didn't mesh fully on the outside. I looked at a blueprint I have for an old timer gear, the blank is cut at 48deg7min. The cut is made at 41deg24min. Tghis would let the outside of the tooth mesh deeper.
