Thanks guys for the info I didn’t realize that a 3 hp water cooled spindle was so weak. I guess once my router is done I’ll have to grab the spindle and see if I still have any fingers left. Jk I would never get my hands near any equipment while running. I have no desire to be a victim of natural selection.
Thanks for the thread mill cutter idea, I just figured that since my router is super rigid and my controller supports rigid tapping it was worth asking. But since the general consensus is I would need a spindle like a vmc has the dream is dead and I will have to try a thread mill cutter.
