straight and square
I have a piece of wood and would like to make a straight line to mark a cut. If I use a ruler to mark the line I’m certain the line will be straight, but there is no guarantee it will run at a right angle to the edge of the board.
One solution to this predicament is to use a rafter angle square in place of a ruler. If I slide the lip of the square against the side of the work piece, the straight edge that is at a right angle to the lip lets me mark a perfect cut line.
After making the cut I have two pieces of wood and I want to glue them together at a right angle. My rafter angle square would help me place the pieces at a right angle, but they could shift out of place as the glue cures.
The best way to ensure a perfect right angle is to use a corner clamp. All I have to do is place the pieces of wood in the clamp at a right angle and turn the handle to secure them. When the wood glue has cured they will be perfectly perpendicular.
