I've been there and done that. Luckily, I still have all of my fingers and thumbs! I'd venture to say that if you don't have several machines already set up (2 - 3 tablesaws, 1 with dado, rip fences all set, etc) a router table or something for the side frame board, etc) its somewhat a waste of time, in my own humble opinion. You need to have many machines all set and take an assembly line approach.
Lets put it this way, if you aren't doing many, many frames, it would be like starting up a 12 row corn picker to go pick a dozen ears of corn!
So many settings for the table saw, changing to a dado, adjusting the fence, than if your doing grooved or wedge there are so many cuts to be made. Assembly, etc!
I will finalize this with this fact, some people have more patience than me and actually enjoy doing these types of things. There is nothing wrong with that. Also, some people are somewhat strapped for money (especially in this economy) and unfortunately have more time than money due to lay-offs, etc. So, a man's gotta do what a man's gotta do to get by in this world. So, if that's you, and you either want to or need to, it can be done. I had to try it myself once, as I thought it would be fun, boy was I wrong.
I used 3/4" boards either 4" or 6" wide, can't remember
