I got to thinking about this Brad and it might be easier to practice using some thin wood. Maybe a couple pieces of BB plywood or something like that. Just to get the idea fixed in your mind. I know, at least I think I know, the thinner the wood, the more table angle you need. So with that said, if you can get the idea worked out then it's just a matter of figuring out what angle you will need for 1/2". I'm thinking something in the area of 2 degrees.
