[HELP] Cutting a flute on a tap

[ieezitin]

Makes perfect sense to me Tom & Dave, I will use a ball end mill..... Now i am going to figure the math to get the cutting edge dead on center, I am going to go with three flutes, Actually I have threaded the bore out but its a little too tight so this tap is just a chaser..

Great thanks for the help... ill post the machining and hardening process.
