Are K'NEX Hinges and Ball'n'Socket joints the same length? Answered
Well, that's my question. I would like to know because I see people make mag's with he hinges on the out side and the ball'n'socket joints on the inside of the sides of the mag, and It is useful info anyhow. Look a the pic...if they are the same length, how did Senior Waffleman make that mag?
