I am going to show how to turn hardwood into frame wood.
This isn't a very long Instructable, but I wanted to show it.
Look at the steps, and use up that hardwood!
Step 1: Cutting the Hardwood
The parts I have marked need to come off.
Adjust your table saw height to 1/16" higher than the bottom notch. Cut off the side with two notches first, only cut off the bottom and slightly smaller one.
Turn your board around. Next, move your blade up as high as it can go, as it will splinter less if the blade is cutting at that height. Cut it, and sand the sides.
