Old And New Ways Of Rifling A Barrel

One of the new ways, by cold hammer forging the grooves in:

Frankly they are both frightening as hell!  The 2nd video isn’t specifically firearm related, but the process is similar.  I cringed every time that hammer came down and struck the object… that’s TONS of force per square inch.

To use a Workaholics reference… both processes are so tight butthole.

Thoughts?

  2. Once saw some video of a rotary forge working a 155mm barrel; ‘impressive’ is an understatement

  3. Very cool. I’ve been kind of brainstorming ways to do this at home without a big expensive piece of equipment like a hammer forge.

    I saw a video of how the Kentucky long rifles were made by hand, and two guys were working on a bench with some sort of mechanical device that didn’t really resemble the one in the first animation.

    I used to work at a forge shop, we didn’t do barrels but we did the pintle mount for a Ma Duece. Those prints were dated 1936.

    The coffee on my desk had rings like in Jurassic park all day long.

  7. State Street provides asset-management activities and its
    business in investments such as mutual funds could fall under limits as
    proposed under the Volcker Rule. Mr O’Donnell said was very methodical and businesslike, ran for a number of other brokerage firms.
    Conceivably, though the capital costs and additional
    required financing are significant, the process is established and the risk of long-term collapse in oil prices is
    relatively low.
