Plug Building Article in The Fisherman

[fishbones]

Anyone read it in this weeks issue? I don't do much building, but found the charts on wood density, plug diagrams, etc... pretty cool. The article could have probably contained much more information, as it was very limited.

My question about the article is this. What is the pin method for attaching hooks? There is a diagram and a brief mention of it, but it seems a little strange to me. I'm just curious about it, as I through-wire the handful of plugs I make each year. Thanks in advance for any answers.
