Always wait for a circular blade to completely stop before pulling from a cut. Otherwise it may bend or kickback.
Gas logs release a lot of water vapor when they are burning. You should be wary of mold and mildew, especially if you have asthma and respiratory problems, when using them for longer than a few hours. A CO detector is a great gas-log accessory. You can find one in many home-improvement and mass chain stores
If your smaller projects call for clear pine without any knots, you can save money by buying a lesser grade, then cutting out what you need from the clear areas between the knots. Also, when buying wood, remember that face grain is not critical for structural parts which won't show. You can likewise save on lumber costs if you can use shorter or narrower boards, or if you only need one good side of lumber for your project.
