How Does This Adjustable Cut Off Jig Work?

[fjl]

I was reading up on this site and saw this supposed nifty woodworking jig. I read it a few times but I guess I must be brain dead or probably cause its almost 2 in the am but I'm got getting how this jig works.

I guess unless I see pics of it in action, I'm not really understanding how it does what it's supposed to do. Maybe one of you can try explaining it or show some pics of it in action.


Cause right now I'm just like...

A sled like this is used to make true 90 degree cuts in small pieces of wood.  The strip of wood on the bottom rides back and forth in the miter slot on a tables saw.  You hold a piece of wood along the strip at the back, ensuring that it is square with the blade.  Then you just push the whole sled to cut the piece.

Imagine this blue rectangle is the piece you need cut...

Another good illustration

Here's mine on top of the saw. I used a double runner system so the off cut would be supported as well. I think the single runner styles are best for squaring large panels.

Okay, I finally get it. It requires a table saw which I don't have. No wonder, I couldn't figure it out.
