Joe, if you're serious here, I'd like to point out that this is a forum dedicated to video games from the 1990s, and not carpentry or some other construction format. Surely, with the many resources of internet search engines these days, you can find the answer you seek.
I'd also like to point out that in chat, whenever a subject comes up, no matter how obvious or mundane, you often go out of your way to post a Wikipedia or Google link. This seems like a situation where that line of action would actually be helpful. Godspeed, joeseph.
