Well, forging anyway. Nothing electronic here at all, just giant white hot metal ingots being formed. Next time you burn yourself soldering (or my your wife complains about soldering fumes), pull this video out and count your blessings!

    Hmm: splined end. Drive shaft for a monster servo?

    Wow, yeah, never mind all that 3d printer nonsense. Give me big hammer!

    Forging. Fire. Primal power.

    You can find pictures of finished gears and such from Kielbergs Steel on their website here.

    I'm suprised that they can sufficiently round gear axles just by hammering them. It seems to me that you could get close but that there would always remain a mark from the very last hammering. Do they have some sort of roller thing they feed axles through after they're done hammering, or is just hammering actually enough?

    I'm not a blacksmith, but I'd try hammering with progressively less force/impact.

    I worked in a steel mill at one time. Once I had to work on a controller system for a conveyor carrying steel that was poured 20 feet away. The controller was about 5 feet from the belt. I was told by my boss not to stay in the area more than 10 minutes and to take out my contacts since they could melt. Needless to say it gave me a new perspective on what hot was.

    After forging, the critical areas would be machined. If heat treatment was required, final machining would be after that. Certain surfaces might also be locally hardened, including having local surface chemistry modification (carbiding, ntriding, etc), or other treatments.
