Chinese Premier Upset over balls and sockets

Postby toad » Fri Jan 29, 2016 5:39 pm

It seems he has found out that China doesn't have any company that can make the balls for a ball point pen. I did a little looking and the ball not only has to be precise and hard but they also require a texture to help hold the ink. Apparently it was cheaper for Chinese manufacturers to just buy balls and sockets then do the assembly work. The materials used seem to be tungsten carbide, steel, and for throw a way's, some use brass.

Reminds me a bit of how the Soviets copied the B-29 from some that were interned during WWII.

Their sheet metal industry apparently couldn't roll sheet aluminum as thin as their American counterparts, so they built the planes out of thicker metal and beveled the edges to make things fit. The performance of the Soviet copy was notably reduced versus the American due to the extra weight.

Wasn't that they couldn't make it as thin, it was US was made in fractional inch thickness and Soviets used Millimeter based. So they could go to thin or too thick. The engineers tried to re-engineer it for their industry, and Stalin sent them to the Gulag for that since he wanted an exact copy. I like the leading edge bullet hole pre drilled though. :lol:
