Put an LCD in your Poker Table

Step 5 Find the placement of the LCD opening

Now that you know how big of a rectangle you need to cut in that nice, flat, SOLID piece of board that is going to be your poker table, you need to figure out where to put it.

To do so, we took a wooden ruler and at one end punched a stick-pin through it, and about half way down drilled a hole just big enough for the end of a marker. This is our high-tech arc-maker-thingy.

To draw out the rectangle...

1.) Find the center of the table from both sides and from both ends. Mark as Point A.
2.) Draw a line down the center of the table through the center point.
3.) Using the center point, mark two edges of the opening by measuring out from the center. Mark as Point B, and Point B. If that makes sense.
4.) Measure out from those two edge points and make two additional marks, Points C and C. It's very important that these two marks be exactly the same distance from Point B.
5.) Using our fancy arc-maker-thingy, draw two intersecting arcs using each Point C as the center.
6.) Draw a line between the two intersections of the arcs, creating a perfectly perpendicular line to use as the edge of the opening.
7.) Measure out from the center line to find the tops and bottoms of the opening, a mark these points as Point D.
8.) Using the four Point D's, connect the dots and draw the top and bottom of the opening.

You should end up with a rectangle just the right size to slip the edging through. You can verify this opening will be square ( right angles at all four corners ) by measuring the distance between opposite corners. If the two diagonals are the same length, you have done a great job.

Also, you might as well make sure the edging and glass will fit within the hole as well. I just taped the edging together and laid the edging and the glass over the hole. Looks like a good fit to me.
