"JointAbility - A great tool for the shop"

	Edges that look good are important, but, the real test is will multiple boards fit perfectly together when they are glued up? That is what I want to find out now.    For the test, I have three 5/4" white oak boards that have "ok" edges but no where good enough to glue up.
You can see that one boards has an imperfections that must be cut out first.    My first step is to mark them in the order I want them to be when joined. This I would do normally after I have selected the boards based on their grain patterns
	For this test, I am going to add a heavy mark of "A" and "B" on each board. This is just for this demonstration to illustrate a point — more on that in a second.
I will start by placing the board that needs to be sawn to get rid of that big gouge. I place it in the JointAbility just enough to see the gouge.    This was on the "B" side so I place it on the "B" side of the JointAbility.  I have placed a temporary marking on the jig itself just for this demonstration.
	There is more than 1/8" of wood to remove so I will use the circular saw that is mounted to the adapter plate. Note that my left hand is resting on the guide bar and my thumb is holding the saw adapter plate to the guide.
Now, with that rip complete, I can use the router to edge this side perfectly.
	Now to the other edges. You can see that they are all close but definitely not close enough.
I will place the first board in the JointAbility. I am going to edge all the "A" sides of the near side of the JointAbility and the "B" sides on the far side.    By the way, the reason for doing "A" and "B" edges is so that they will always mate even if the guide bar isn't perfectly straight. The guide bar here is as straight as it can be, but I will use this A/B method anyway — it can't hurt.
	I make my first edge cut — the "A" side of this board. When this is done, I undo the clamps and slide the "B" side into position and route that edge.
A few minutes later and I have edged the other boards and can now inspect the joints.
	They are perfect. Perfect is when they meet the entire length and can be glued up with just enough clamp pressure to produce minimum squeeze out.    The JointAbility is working well so far. But I have more in store. Next week, I start a blanket chest "to beat all blanket chests." The JointAbility will get a workout in this project.    I have another surprise too. See you next week.
