I need to machine some metric trapezoidal threads. Both internal and

What's the best way to do that?

Is hand grinding the tools going to be my best approach? I think maybe it
is since they are for making molds of two mating parts. The molds can't
be of the exact thread forms or the parts won't fit together. A proper
cutting tool for those threads might not produce what I need. I'm still
thinking my way through the process.



There's guy on Youtube that ground his own tools for making ACME
threads. Same thing as trapezoidal. Only different.
He has a channel.

Thanks Steve. I actually follow his channel and I've seen the "ACME?
Ac-You" title a few times. I don't think I ever watched it before. Thanks
again.
