Deacon , I use to watch a Canadian PBS broadcast called Router Workshop . These guys are so good that they can make a picture frame ,take a picture ,and cook moose burgers , all with a router . I got on their website and in there 400 series dvd number 402 for $4.95 you can get a wealth of information about framing . I wouldn't be suprised if they would show you how to get accurate miters with a router . Just a thought .............John
