Buying advice: woodworking

Clamps, a combination square, a good saw and a drill cover most beginner projects.
You can never have too many. Bar clamps handle wide glue-ups; quick-grip clamps are fast for smaller work.
Standard wood glue suits indoor projects. Water-resistant glue suits outdoor work and cutting boards.
Oils are easy to apply and repair. Polyurethane and varnish protect tabletops and floors better.
Eye and hearing protection and dust collection matter from the first project. Lay oily rags flat to dry to prevent fires.
