re: How to

Pic # 2.   I want a rabbet on each side. Solid wood down the center.In the pic, those rabbets are 3/4" wide x 3/8" deep. I need to get 1 1/2" wide x 3/8" deep. I want to cut the rabbets on a long strip 4 " wide, then cut the strip into the 4 pieces to make a box.

This sounds like a perfect job for a handplane that I don't have.
