Thinking about building a pocket hole machine. There are two types, drill, based upon Kreg Foreman, and router, similar to Castle 100. I'm leaning towards router based. ShopNotes (issue 42) had such a machine. Woodsmith's weekly tips recently featured this machine. Unfortunately, you have to drill pilot hole for screw using a hand drill. ShaweneeHills Woodworking has a video showing how he built his, which includes drill in machine. Everything is controlled by a single lever, like the old Porter Cable 552 machines. Thinking about building the ShopNote's version, with drill attached. Anybody actually built either type of pocket hole machine?
