I have spent some time looking for a tutorial on creating tabs. Never done it. So, I am using a sled. 1.5 inches thick. My project board is .75 inches thick. I made an outline and selecting the cutting bit. Then went in and made tabs. Seemed simple enough. However, I dont know what to do with the settings that pops up. Tab Height and width I got, but tab depth? Can someone break this down Barney style for me?
