During testing, the first rifled, cobalt-alloy machine gun barrel ever produced using the "flow forming" process consistently reached high temperatures without degraded performance.

Ron Covell shows us how to properly use a planishing hammer, which can allow you to do a lot of different variations of forming when it comes to making parts!

In flow forming process, the inner barrel of the wheel is put under pressure once casted while it is being spun at high speed, which makes the product thinner and lighter.
