Do I need to be there for the inspection? It's not required, but it's a good idea. Following the inspection, the home inspector will be able to answer questions about the report and any problem areas. This is also an opportunity to hear an objective opinion on the home you'd like to purchase and it is a good time to ask general maintenance questions.

Professional woodworkers buy quality tools capable of precision adjustments. Two tools which give them a leg up are the thinckness planer and planer/joiner. If you don't have these tools to help make sure your stock is perfectly dimensioned, try to find someone who has them and will dress up your project lumber for you. Chances are good that the wood you buy from the lumberyard will not be precisely square and true, and will need further processing if you are building a project to critical dimensions.
To store a carpenter's square, nail either a 13-in. or 22-in. length of tongue-and-groove flooring to your shop wall, groove side up. Then, to hang your square, just drop one leg of the square into the groove of the flooring piece. The length depends on which leg you want to be horizontal.
