And now the fragrance of fresh cut wood fills the air   

For everything to fit together nicely without stress, the cuts need to be precise. I try to get within 1/32 of an inch. The Bosch miter saw is one of the best tools I've purchased for my shop. It enables me to achieve the kind of precision I want. I also use a sharp, good quality, carbide-tipped blade, which makes cutting through oak more like slicing warm butter (except cut wood smells better).
