WOOD magazine's Editorial Process Published on October 18, 2016 Wondering which size biscuit best suits your project parts? Make this simple gauge to show the width of #0, #10, or #20 biscuits and the slots that hold them. Simply mill a slot for each size, glue in a biscuit—making sure you push it in only halfway—and mark a centerline for each. Then line up the centerline on your gauge with the layout line on your workpiece for a quick reference on which to use. (Use the largest biscuit possible for maximum strength.)—from the WOOD shop Was this page helpful? Thanks for your feedback! Tell us why! Other Submit
