Tip # 1
The key to woodworking is to have the correct tools and the ability to use them.  If you are a first-timer at building something out of wood, I would suggest two things.  First, pick a project that is relatively small and simple.  By doing this, you get a feel for your tools, plus you gain some very important experience.  Second, read the instructions to your tools very carefully, and practice a time or two on some scrap wood.  After over 35 years of working with wood and using woodworking tools, experience seems to be one of the most important aspects of building something you and others will be satisfied with and happy to show others.
Tip # 2
Whether you are an experienced or a beginner at woodworking it is always important to study and understand the plans of your project.  Be sure you have mastered the techniques you are using to build your project, and you have the correct tools to do them.  Remember to always be safe when using any and all power tools.
Tip # 3
To insure quality finished products be certain your tools are running properly and all cutting surfaces are sharp and clean.  Maintaining your shop and your tools is vital to creating valuable products and having an enjoyable time while following the steps to your woodworking plans.  Another important issue when working with wood is knowing the types of wood that are available and then choosing the correct wood for your project.
