Allright, guys. Mrs. Yoda has just informed me that we have dinner reservations with friends in thirty minutes. After a moment or two of questioning her priorities -- and her mine -- I have decided to pen this short note to get you started. I'll get back ASAP.

Hats off to Martee for providing the photographs in this post. He's done another excellent job and is contributing mightily to this study. Thank you, Martee!

Okay, get all your 'other' hinge stuff -- Doug, do you remember where you put yours? -- and let's get started. Here's what we'redoing.

First, we will assemble your 'model' Club. That is what the mending plates are for. Now, as you'll see in the picture below, Martee has some world-class plates. My own are a fraction of that size -- not quite an inch in width. So, if your's don't look like his, you are not alone!

Actually, other than being a bit less portable -- I like to keep mine in my Golf Bag for the 911 calls I get on the range -- they're great for our purposes. A nice big fat model Club. No missing this one and thePlane of Motion it will describe!

So, put your two mending plates together using your thumbscrews or wing nuts. Use the washers, too, because in Lesson Three, we're going to be adjusting the assembly some what, and we need to be able to stabilize the assembly in any configuration. Once you've got the two pieces bolted together, hold the 'Clubface' level to the ground and angle the "Shaft" somewhat to fit the Inclined Plane of your choice.

Once you built your model 'Club,' attach it to the Horizontal Hinge as shown in the photo. Use your thumb screw or wing nut for anice firm attachment. Once in this configuration, there should be no 'wobble' in the assembly.

Okay...get to work, and make yours look like this:


Now, keeping the integrity of the Horizontal Hinge and its Horizontal Plane of Motion -- in other words, keeping the Horizontal Hinge Pin VERTICAL to the ground...

Just mess with it.

Swing the little 'Club' back and forth from its Horizontal Hinge. Watch it move in a circle. Most of all...

WATCH THE CLUBFACE OPEN AND CLOSE.

No actual "Turning or Rolling" of anything, just the pure rotation of a Blade about its Hinge. And because the Clubface is now attached to the Hinge, it describes the same motion. The Clubface merely Opens and Closes. It does not lay back! Not in the slightest. And it won't. Why?

Because it is attached to the blade of a Horizontal Hinge. And a Horizontal Hinge blade stays vertical (perpendicular) to its own Plane of Rotation.

"I'm coming! Be right there! I know we're late! I've got responsibilities, for cryin' out loud!"

Gotta run. I'll post homework when I get back. See you soon.
