You will need basic hand tools, a circular saw, a drill (a second drill or powered screwdriver is a good idea), and probably a jigsaw. A belt-sander will be quite handy, and possibly a router (but it's not required). You won't need a table-saw or powered plane, but if you have them we're sure you will find some task to keep them warm. No welding is required in any of our projects. An orbital sander would speed up the finishing process quite a bit. It's possible to build these projects with hardly any tools at all, but we certainly don't have that much fortitude!
