I got an air compressor this past XMas. With the economy down, the prices on tools at Harbor Freight have been almost a givaway! I've been buying tools like crazy (to my wife's disdain)! I built a small work bench/Pegboard. It turned out fairly well! I have a few jobs to do this spring. Put up a fence, put up a shed, and put up an outdoor doghouse/kennel. I plan to build a lot of the stuff I need to work myself. My next project is making some knockdown sawhorses. I plan on modifying them to accept some 2x4 stretchers to create a knockdown work support. I figure I can just cross a couple notched 2x4's to rip or crosscut sheets if I need to. Then, I'll use OSB hinged in the middle to create the top for a knockdown work table. I also need to create a saw guide for my circular saw. I'm thinking that since I'll be cutting a lot of 4x4 and 2x4 stock for my spring projects, a 10" miter saw might be a good investment. I know that a table saw is the first recommended tool for woodworking, because it can miter as well, but I'm guessing that's more for furniture making than mitering long utility stock for framing and fence making.

Anyway, my question for the fence is, do you recommend putting the 4x4 posts in concrete? It will be meant to hold in a sizable dog. IS it 1/2 bag per post? For the shed, should I just put down some 4x4's on the ground or dig in concrete footers for that as well? Levelling the thing will probably be a pain otherwise?
