Jon are you talking 1/2" high or 1/2" thick? I'm guessing you mean 1/2" thick for this reply. At 1/2" thick both Stick and I will recommend that you consider splining the edging on instead. There are a couple of reasons for this. All the other edge banding techniques involve making a male and a female joint. When you make the the male side you lose some width of material. The setup is also more complicated as you have to match the two bit profiles for height. In a spline setup you have one setting that you run both sides through (either face up or face down) so you can't get that part wrong plus no material width is lost as you only made a groove in both pieces. The spline can be made from a piece of scrap wood or even something like hdf. The spline joint is much simpler, requiring either a slot cutter for the router or the blade on a table saw.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
