Its made by cutting off about 3.5in from a 6" wide oak plank. (I think the actual width is slightly less). This is a standard width you can find at most lumber yards. You can make it wider if you want by cutting off a longer piece.
Then I set the table saw blade at a 27deg angle and cut off the tip of the block at this angle. This makes the front of the stand that is visible angle back.
Next I repositioned the guide to scoot over a bit and cut the grooves for the iPad to sit in. You need to back the depth off (using some scraps to test your depth). I made the first cut then repositioned the guide to make a second cut 1/16th in over, then kept moving the guide little by little to get about 1 1/4" gap. Then I set the saw back to 90 deg and adjusted the depth to match the depth of the angle cuts and continued the groove back little by little until I liked the angle the iPad would sit at.
Finally, I lowered the blade down, flipped the block over and cut a shallow groove to allow the sync cable to run under the block.
Currently, I'm looking for some kind of rubberized stick-on material to put on the bottom to give it a nice solid feel. Sometimes when I tap the screen the block will pivot from having a slick finished bottom and sitting on a slick finished desk.
