Step 7 Make Guides

Set up your marking gauge to scribe the tenon width on the center of the board end. For 13/16-in.-thick stock the tenon is usually 3/8 in. thick with 7/32-in. shoulders on both sides. But a 5/16-in.-thick tenon with 1/4-in.-thick shoulders is also perfectly acceptable. Scribe these guide lines across the end grain and down the two edges till they meet the shoulder line.

it's a scribe. it marks at a fixed distance. here's how to make one: http://www.youtube.com/watch?v=HAB8cX_qiVA

...or you can just use an adjustable square ("combination square"?) and mark each end of the line
