Actually I'm not an intern, Im a counstulant engineer because I already have one degree and yes I agree they are typically tapped before hardening but I just felt its silly to have 2 or 3 wasted gears I definitely have the equipment and getting a carbide bit isn't the issue because I figured out I can go up in screw size and i tested the gears 35 and 38 Rockwell so here's my thought process on how to accomplish this corodrill bit rates for up to 50 rockwell so then find a tap and throw it in the mill write the program and have the mill tap it
And I just love the engineering challenge it's kinda why I want to design an RC truck and machine out all the components at some point and I believe I have figured out how I'm going to drill it with the mill too
