Scott, I noticed in another thread you've had your table saw for all of two weeks. I just wanted to follow up and really encourage you to find a different way to edge joint boards than the jig you mentioned in this thread. There are safer options, even an option to still do it on your table saw in a much safer manner that is just like ripping a board.
I am a big fan of doing things safely. This is a potentially dangerous hobby with all kinds of tools that can easily remove fingers (or more) - and sometimes even take a life. I encourage you to check out our
Shop Safety sub-forum and take a look through there.
If something happens where the saw catches and kicks back the board, you will not like it. I've read accounts of boards flying with enough force to cause internal bleeding. I've seen my own table saw shoot a 2" x 2" x 3/4" piece of wood out and damage a wall 20' away. No one has enough strength to manhandle a board and try to shut the saw off if the piece starts to kick back.
Bad things can happen in a hurry, sometime even when you're doing things safely. And even seasoned woodworkers have mishaps or moments where they are distracted or don't do something safely.
Here are some things that have happened to some of our members here. Warning, there are graphic pictures in some or all of these threads. And, honestly, you don't have to look very far on the internet to find countless stories from guys who have seriously injured themselves - sometimes to the point of affecting their entire life and livelihood. There have even been people who have died due to injuries sustained while woodworking.

This is a great and fun hobby, but you need to practice it safely. While you might be able to safely use that jig for many years, this is probably one of the least safe ways to edge joint a board. I've done some stupid stuff with my tools, usually when the tool is new to me, and have gotten hurt. Thankfully not seriously. It's definitely made me learn some lessons about safely using my tools and practicing this hobby. I know the last thing I want to do is lose a finger or get injured to the point where I can no longer have woodworking as my hobby or, worst of all, leave my wife as a widow and my two young sons without a father because I did something stupid with a potentially dangerous power tool.
Sorry for the serious/doom and gloom post. But I don't want to see you making a thread in the shop safety forum wherein you show a graphic and bloody picture and describe how you lost a finger, or got injured in some other way, because you didn't do something in the safest manner you can.
