Now, I'm not 100% certain he is using a sled from the pictures in the eBook Most Excellent, but he is certainly supporting the wood with another piece of wood. He also uses a "sacrificial" piece of wood against the back of the cut to prevent tear-out, something that frequently happens when sawing or drilling wood without the additional support.
Well, heck, here's the photo of the cut from the eBook Most Excellent (he has removed the spacer):
As you may recall, I decided to cut the sharps on the band saw with its table tilted at 10 degrees. Big mistake. Okay, maybe not a big mistake, but I really should have cut them on the table saw because it would have prevented the wee, little cut marks on the sides that I had to take the time and effort to sand away. And you know by now how much I love sanding.
So, the moral of the story is to follow the directions, especially when they've been created by a guy who's been at it for 30 years and has been generous enough to share his knowledge with the world as Mr. Miller has.
Lesson learned (again).
